NAME cmakemodules - Reference of available CMake modules.

DESCRIPTION The "cmake" executable is the CMake command-line interface. It may be used to configure projects in scripts. Project configuration settings may be specified on the command line with the -D option. The -i option will cause cmake to interactively prompt for such settings.

CMake is a cross-platform build system generator. Projects specify their build process with platform-independent CMake listfiles included in each directory of a source tree with the name CMakeLists.txt. Users build a project by using CMake to generate a build system for a native tool on their platform.

MODULES The following modules are provided with CMake. They can be used with INCLUDE(ModuleName).

CMake Modules - Modules coming with CMake, the Cross-Platform Makefile Generator.

This is the documentation for the modules and scripts coming with CMake. Using these modules you can check the computer system for installed software packages, features of the compiler and the existence of headers to name just a few.

AddFileDependencies ADD_FILE_DEPENDENCIES(source_file depend_files...)

Adds the given files as dependencies to source_file

BundleUtilities Functions to help assemble a standalone bundle application.

A collection of CMake utility functions useful for dealing with .app bundles on the Mac and bundle-like directories on any OS.

The following functions are provided by this module:

fixup_bundle copy_and_fixup_bundle verify_app get_bundle_main_executable get_dotapp_dir get_bundle_and_executable get_bundle_all_executables get_item_key clear_bundle_keys set_bundle_key_values get_bundle_keys copy_resolved_item_into_bundle copy_resolved_framework_into_bundle fixup_bundle_item verify_bundle_prerequisites verify_bundle_symlinks

Requires CMake 2.6 or greater because it uses function, break and PARENT_SCOPE. Also depends on GetPrerequisites.cmake.

FIXUP_BUNDLE(<app> <libs> <dirs>)

Fix up a bundle in-place and make it standalone, such that it can be drag-n-drop copied to another machine and run on that machine as long as all of the system libraries are compatible.

If you pass plugins to fixup_bundle as the libs parameter, you should install them or copy them into the bundle before calling fixup_bundle. The "libs" parameter is a list of libraries that must be fixed up, but that cannot be determined by otool output analysis. (i.e., plugins)

Gather all the keys for all the executables and libraries in a bundle, and then, for each key, copy each prerequisite into the bundle. Then fix each one up according to its own list of pre- requisites.

Then clear all the keys and call verify_app on the final bundle to ensure that it is truly standalone.

COPY_AND_FIXUP_BUNDLE(<src> <dst> <libs> <dirs>)

Makes a copy of the bundle <src> at location <dst> and then fixes up the new copied bundle in-place at <dst>...

VERIFY_APP(<app>)

Verifies that an application <app> appears valid based on run- ning analysis tools on it. Calls "message(FATAL_ERROR" if the application is not verified.

GET_BUNDLE_MAIN_EXECUTABLE(<bundle> <result_var>)

The result will be the full path name of the bundles main exe- cutable file or an "error:" prefixed string if it could not be determined.

GET_DOTAPP_DIR(<exe> <dotapp_dir_var>)

Returns the nearest parent dir whose name ends with ".app" given the full path to an executable. If there is no such parent dir, then simply return the dir containing the executable.

The returned directory may or may not exist.

GET_BUNDLE_AND_EXECUTABLE(<app> <bundle_var> <executable_var> <valid_var>)

Takes either a ".app" directory name or the name of an exe- cutable nested inside a ".app" directory and returns the path to the ".app" directory in <bundle_var> and the path to its main executable in <executable_var>

GET_BUNDLE_ALL_EXECUTABLES(<bundle> <exes_var>)

Scans the given bundle recursively for all executable files and accumulates them into a variable.

GET_ITEM_KEY(<item> <key_var>)

Given a file (item) name, generate a key that should be unique considering the set of libraries that need copying or fixing up to make a bundle standalone. This is essentially the file name including extension with "." replaced by "_"

This key is used as a prefix for CMake variables so that we can associate a set of variables with a given item based on its key.

CLEAR_BUNDLE_KEYS(<keys_var>)

Loop over the list of keys, clearing all the variables associ- ated with each key. After the loop, clear the list of keys itself.

Caller of get_bundle_keys should call clear_bundle_keys when done with list of keys.

SET_BUNDLE_KEY_VALUES(<keys_var> <context> <item> <exepath> <dirs> <copyflag>)

Add a key to the list (if necessary) for the given item. If added, also set all the variables associated with that key.

GET_BUNDLE_KEYS(<app> <libs> <dirs> <keys_var>)

Loop over all the executable and library files within the bundle (and given as extra <libs>) and accumulate a list of keys repre- senting them. Set values associated with each key such that we can loop over all of them and copy prerequisite libs into the bundle and then do appropriate install_name_tool fixups.

COPY_RESOLVED_ITEM_INTO_BUNDLE(<resolved_item> <resolved_embedded_item>)

Copy a resolved item into the bundle if necessary. Copy is not necessary if the resolved_item is "the same as" the resolved_embedded_item.

COPY_RESOLVED_FRAMEWORK_INTO_BUNDLE(<resolved_item> <resolved_embedded_item>)

Copy a resolved framework into the bundle if necessary. Copy is not necessary if the resolved_item is "the same as" the resolved_embedded_item.

By default, BU_COPY_FULL_FRAMEWORK_CONTENTS is not set. If you want full frameworks embedded in your bundles, set BU_COPY_FULL_FRAMEWORK_CONTENTS to ON before calling fixup_bundle. By default, COPY_RESOLVED_FRAMEWORK_INTO_BUNDLE copies the framework dylib itself plus the framework Resources directory.

FIXUP_BUNDLE_ITEM(<resolved_embedded_item> <exepath> <dirs>)

Get the direct/non-system prerequisites of the resolved embedded item. For each prerequisite, change the way it is referenced to the value of the _EMBEDDED_ITEM keyed variable for that prereq- uisite. (Most likely changing to an "@executable_path" style reference.)

This function requires that the resolved_embedded_item be "inside" the bundle already. In other words, if you pass plugins to fixup_bundle as the libs parameter, you should install them or copy them into the bundle before calling fixup_bundle. The "libs" parameter is a list of libraries that must be fixed up, but that cannot be determined by otool output analysis. (i.e., plugins)

Also, change the id of the item being fixed up to its own _EMBEDDED_ITEM value.

Accumulate changes in a local variable and make *one* call to install_name_tool at the end of the function with all the changes at once.

If the BU_CHMOD_BUNDLE_ITEMS variable is set then bundle items will be marked writable before install_name_tool tries to change them.

VERIFY_BUNDLE_PREREQUISITES(<bundle> <result_var> <info_var>)

Verifies that the sum of all prerequisites of all files inside the bundle are contained within the bundle or are "system" libraries, presumed to exist everywhere.

VERIFY_BUNDLE_SYMLINKS(<bundle> <result_var> <info_var>)

Verifies that any symlinks found in the bundle point to other files that are already also in the bundle... Anything that points to an external file causes this function to fail the ver- ification.

CMakeAddFortranSubdirectory Use MinGW gfortran from VS if a fortran compiler is not found.

The add_fortran_subdirectory function adds a subdirectory to a project that contains a fortran only sub-project. The module will check the current compiler and see if it can support for- tran. If no fortran compiler is found and the compiler is MSVC, then this module will find the MinGW gfortran. It will then use an external project to build with the MinGW tools. It will also create imported targets for the libraries created. This will only work if the fortran code is built into a dll, so BUILD_SHARED_LIBS is turned on in the project. In addition the CMAKE_GNUtoMS option is set to on, so that the MS .lib files are created. Usage is as follows:

cmake_add_fortran_subdirectory( <subdir> # name of subdirectory PROJECT <project_name> # project name in subdir top CMakeLists.txt ARCHIVE_DIR <dir> # dir where project places .lib files RUNTIME_DIR <dir> # dir where project places .dll files LIBRARIES <lib>... # names of library targets to import LINK_LIBRARIES # link interface libraries for LIBRARIES [LINK_LIBS <lib> <dep>...]... CMAKE_COMMAND_LINE ... # extra command line flags to pass to cmake NO_EXTERNAL_INSTALL # skip installation of external project )

Relative paths in ARCHIVE_DIR and RUNTIME_DIR are interpreted with respect to the build directory corresponding to the source directory in which the function is invoked.

Limitations:

NO_EXTERNAL_INSTALL is required for forward compatibility with a future version that supports installation of the external project binaries during "make install".

CMakeBackwardCompatibilityCXX define a bunch of backwards compatibility variables

CMAKE_ANSI_CXXFLAGS - flag for ansi c++ CMAKE_HAS_ANSI_STRING_STREAM - has <strstream> include(TestForANSIStreamHeaders) include(CheckIncludeFileCXX) include(TestForSTDNamespace) include(TestForANSIForScope)

CMakeDependentOption Macro to provide an option dependent on other options.

This macro presents an option to the user only if a set of other conditions are true. When the option is not presented a default value is used, but any value set by the user is preserved for when the option is presented again. Example invocation:

CMAKE_DEPENDENT_OPTION(USE_FOO "Use Foo" ON "USE_BAR;NOT USE_ZOT" OFF)

If USE_BAR is true and USE_ZOT is false, this provides an option called USE_FOO that defaults to ON. Otherwise, it sets USE_FOO to OFF. If the status of USE_BAR or USE_ZOT ever changes, any value for the USE_FOO option is saved so that when the option is re-enabled it retains its old value.

CMakeDetermineVSServicePack Determine the Visual Studio service pack of the cl in use.

The functionality of this module has been superseded by the platform variable CMAKE_<LANG>_COMPILER_VERSION that contains the compiler version number.

Usage:

if(MSVC) include(CMakeDetermineVSServicePack) DetermineVSServicePack( my_service_pack ) if( my_service_pack ) message(STATUS "Detected: ${my_service_pack}") endif() endif()

Function DetermineVSServicePack sets the given variable to one of the following values or an empty string if unknown:

vc80, vc80sp1 vc90, vc90sp1 vc100, vc100sp1 vc110, vc110sp1, vc110sp2

CMakeExpandImportedTargets

CMAKE_EXPAND_IMPORTED_TARGETS(<var> LIBRARIES lib1 lib2...libN

[CONFIGURATION <config>] )

CMAKE_EXPAND_IMPORTED_TARGETS() takes a list of libraries and replaces all imported targets contained in this list with their actual file paths of the referenced libraries on disk, including the libraries from their link interfaces. If a CONFIGURATION is given, it uses the respective configuration of the imported tar- gets if it exists. If no CONFIGURATION is given, it uses the first configuration from ${CMAKE_CONFIGURATION_TYPES} if set, otherwise ${CMAKE_BUILD_TYPE}. This macro is used by all Check*.cmake files which use try_compile() or try_run() and sup- port CMAKE_REQUIRED_LIBRARIES , so that these checks support imported targets in CMAKE_REQUIRED_LIBRARIES:

cmake_expand_imported_targets(expandedLibs LIBRARIES ${CMAKE_REQUIRED_LIBRARIES} CONFIGURATION "${CMAKE_TRY_COMPILE_CONFIGURATION}" )

CMakeFindFrameworks helper module to find OSX frameworks

CMakeFindPackageMode

This file is executed by cmake when invoked with --find-package. It expects that the following variables are set using -D:

NAME = name of the package COMPILER_ID = the CMake compiler ID for which the result is, i.e. GNU/Intel/Clang/MSVC, etc. LANGUAGE = language for which the result will be used, i.e. C/CXX/Fortan/ASM MODE = EXIST : only check for existence of the given package COMPILE : print the flags needed for compiling an object file which uses the given package LINK : print the flags needed for linking when using the given package QUIET = if TRUE, dont print anything

CMakeForceCompiler

This module defines macros intended for use by cross-compiling toolchain files when CMake is not able to automatically detect the compiler identification.

Macro CMAKE_FORCE_C_COMPILER has the following signature:

CMAKE_FORCE_C_COMPILER(<compiler> <compiler-id>)

It sets CMAKE_C_COMPILER to the given compiler and the cmake internal variable CMAKE_C_COMPILER_ID to the given compiler-id. It also bypasses the check for working compiler and basic com- piler information tests.

Macro CMAKE_FORCE_CXX_COMPILER has the following signature:

CMAKE_FORCE_CXX_COMPILER(<compiler> <compiler-id>)

It sets CMAKE_CXX_COMPILER to the given compiler and the cmake internal variable CMAKE_CXX_COMPILER_ID to the given com- piler-id. It also bypasses the check for working compiler and basic compiler information tests.

Macro CMAKE_FORCE_Fortran_COMPILER has the following signature:

CMAKE_FORCE_Fortran_COMPILER(<compiler> <compiler-id>)

It sets CMAKE_Fortran_COMPILER to the given compiler and the cmake internal variable CMAKE_Fortran_COMPILER_ID to the given compiler-id. It also bypasses the check for working compiler and basic compiler information tests.

So a simple toolchain file could look like this:

include (CMakeForceCompiler) set(CMAKE_SYSTEM_NAME Generic) CMAKE_FORCE_C_COMPILER (chc12 MetrowerksHicross) CMAKE_FORCE_CXX_COMPILER (chc12 MetrowerksHicross)

CMakeGraphVizOptions The builtin graphviz support of CMake.

CMake can generate graphviz files, showing the dependencies between the targets in a project and also external libraries which are linked against. When CMake is run with the --gra- phiz=foo option, it will produce

* a foo.dot file showing all dependencies in the project * a foo.dot.<target> file for each target, file showing on which other targets the respective target depends * a foo.dot.<target>.dependers file, showing which other targets depend on the respective target

This can result in huge graphs. Using the file CMakeGraphVizOp- tions.cmake the look and content of the generated graphs can be influenced. This file is searched first in ${CMAKE_BINARY_DIR} and then in ${CMAKE_SOURCE_DIR}. If found, it is read and the variables set in it are used to adjust options for the generated graphviz files.

GRAPHVIZ_GRAPH_TYPE - The graph type Mandatory : NO Default : "digraph" GRAPHVIZ_GRAPH_NAME - The graph name. Mandatory : NO Default : "GG" GRAPHVIZ_GRAPH_HEADER - The header written at the top of the graphviz file. Mandatory : NO Default : "node [n fontsize = "12"];" GRAPHVIZ_NODE_PREFIX - The prefix for each node in the graphviz file. Mandatory : NO Default : "node" GRAPHVIZ_EXECUTABLES - Set this to FALSE to exclude executables from the generated graphs. Mandatory : NO Default : TRUE GRAPHVIZ_STATIC_LIBS - Set this to FALSE to exclude static libraries from the generated graphs. Mandatory : NO Default : TRUE GRAPHVIZ_SHARED_LIBS - Set this to FALSE to exclude shared libraries from the generated graphs. Mandatory : NO Default : TRUE GRAPHVIZ_MODULE_LIBS - Set this to FALSE to exclude static libraries from the generated graphs. Mandatory : NO Default : TRUE GRAPHVIZ_EXTERNAL_LIBS - Set this to FALSE to exclude external libraries from the generated graphs. Mandatory : NO Default : TRUE GRAPHVIZ_IGNORE_TARGETS - A list of regular expressions for ignoring targets. Mandatory : NO Default : empty

CMakePackageConfigHelpers CONFIGURE_PACKAGE_CONFIG_FILE(), WRITE_BASIC_PACKAGE_VER- SION_FILE()

CONFIGURE_PACKAGE_CONFIG_FILE(<input> <output> INSTALL_DESTINATION <path> [PATH_VARS <var1> <var2> ... <varN>] [NO_SET_AND_CHECK_MACRO] [NO_CHECK_REQUIRED_COMPONENTS_MACRO])

CONFIGURE_PACKAGE_CONFIG_FILE() should be used instead of the plain configure_file() command when creating the <Name>Con- fig.cmake or <Name>-config.cmake file for installing a project or library. It helps making the resulting package relocatable by avoiding hardcoded paths in the installed Config.cmake file.

In a FooConfig.cmake file there may be code like this to make the install destinations know to the using project:

set(FOO_INCLUDE_DIR "@CMAKE_INSTALL_FULL_INCLUDEDIR@" ) set(FOO_DATA_DIR "@CMAKE_INSTALL_PREFIX@/@RELATIVE_DATA_INSTALL_DIR@" ) set(FOO_ICONS_DIR "@CMAKE_INSTALL_PREFIX@/share/icons" ) ...logic to determine installedPrefix from the own location... set(FOO_CONFIG_DIR "${installedPrefix}/@CONFIG_INSTALL_DIR@" )

All 4 options shown above are not sufficient, since the first 3 hardcode the absolute directory locations, and the 4th case works only if the logic to determine the installedPrefix is cor- rect, and if CONFIG_INSTALL_DIR contains a relative path, which in general cannot be guaranteed. This has the effect that the resulting FooConfig.cmake file would work poorly under Windows and OSX, where users are used to choose the install location of a binary package at install time, independent from how CMAKE_INSTALL_PREFIX was set at build/cmake time.

Using CONFIGURE_PACKAGE_CONFIG_FILE() helps. If used correctly, it makes the resulting FooConfig.cmake file relocatable. Usage:

1. write a FooConfig.cmake.in file as you are used to 2. insert a line containing only the string "@PACKAGE_INIT@" 3. instead of set(FOO_DIR "@SOME_INSTALL_DIR@"), use set(FOO_DIR "@PACKAGE_SOME_INSTALL_DIR@") (this must be after the @PACKAGE_INIT@ line) 4. instead of using the normal configure_file(), use CONFIGURE_PACKAGE_CONFIG_FILE()

The <input> and <output> arguments are the input and output file, the same way as in configure_file().

The <path> given to INSTALL_DESTINATION must be the destination where the FooConfig.cmake file will be installed to. This can either be a relative or absolute path, both work.

The variables <var1> to <varN> given as PATH_VARS are the vari- ables which contain install destinations. For each of them the macro will create a helper variable PACKAGE_<var...>. These helper variables must be used in the FooConfig.cmake.in file for setting the installed location. They are calculated by CONFIG- URE_PACKAGE_CONFIG_FILE() so that they are always relative to the installed location of the package. This works both for rela- tive and also for absolute locations. For absolute locations it works only if the absolute location is a subdirectory of CMAKE_INSTALL_PREFIX.

By default configure_package_config_file() also generates two helper macros, set_and_check() and check_required_components() into the FooConfig.cmake file.

set_and_check() should be used instead of the normal set() com- mand for setting directories and file locations. Additionally to setting the variable it also checks that the referenced file or directory actually exists and fails with a FATAL_ERROR other- wise. This makes sure that the created FooConfig.cmake file does not contain wrong references. When using the NO_SET_AND_CHECK_MACRO, this macro is not generated into the FooConfig.cmake file.

check_required_components(<package_name>) should be called at the end of the FooConfig.cmake file if the package supports com- ponents. This macro checks whether all requested, non-optional components have been found, and if this is not the case, sets the Foo_FOUND variable to FALSE, so that the package is consid- ered to be not found. It does that by testing the Foo_<Compo- nent>_FOUND variables for all requested required components. When using the NO_CHECK_REQUIRED_COMPONENTS option, this macro is not generated into the FooConfig.cmake file.

For an example see below the documentation for WRITE_BASIC_PACK- AGE_VERSION_FILE().

WRITE_BASIC_PACKAGE_VERSION_FILE( filename VERSION major.minor.patch COMPATIBILITY (AnyNewerVersion|SameMajorVersion|ExactVersion) )

Writes a file for use as <package>ConfigVersion.cmake file to <filename>. See the documentation of find_package() for details on this.

filename is the output filename, it should be in the build tree. major.minor.patch is the version number of the project to be installed

The COMPATIBILITY mode AnyNewerVersion means that the installed package version will be considered compatible if it is newer or exactly the same as the requested version. This mode should be used for packages which are fully backward compatible, also across major versions. If SameMajorVersion is used instead, then the behaviour differs from AnyNewerVersion in that the major version number must be the same as requested, e.g. version 2.0 will not be considered compatible if 1.0 is requested. This mode should be used for packages which guarantee backward compatibil- ity within the same major version. If ExactVersion is used, then the package is only considered compatible if the requested ver- sion matches exactly its own version number (not considering the tweak version). For example, version 1.2.3 of a package is only considered compatible to requested version 1.2.3. This mode is for packages without compatibility guarantees. If your project has more elaborated version matching rules, you will need to write your own custom ConfigVersion.cmake file instead of using this macro.

Internally, this macro executes configure_file() to create the resulting version file. Depending on the COMPATIBLITY, either the file BasicConfigVersion-SameMajorVersion.cmake.in or Basic- ConfigVersion-AnyNewerVersion.cmake.in is used. Please note that these two files are internal to CMake and you should not call configure_file() on them yourself, but they can be used as starting point to create more sophisticted custom ConfigVer- sion.cmake files.

Example using both configure_package_config_file() and write_basic_package_version_file(): CMakeLists.txt:

set(INCLUDE_INSTALL_DIR include/ ... CACHE ) set(LIB_INSTALL_DIR lib/ ... CACHE ) set(SYSCONFIG_INSTALL_DIR etc/foo/ ... CACHE ) ... include(CMakePackageConfigHelpers) configure_package_config_file(FooConfig.cmake.in ${CMAKE_CURRENT_BINARY_DIR}/FooConfig.cmake INSTALL_DESTINATION ${LIB_INSTALL_DIR}/Foo/cmake PATH_VARS INCLUDE_INSTALL_DIR SYSCONFIG_INSTALL_DIR) write_basic_package_version_file(${CMAKE_CURRENT_BINARY_DIR}/FooConfigVersion.cmake VERSION 1.2.3 COMPATIBILITY SameMajorVersion ) install(FILES ${CMAKE_CURRENT_BINARY_DIR}/FooConfig.cmake ${CMAKE_CURRENT_BINARY_DIR}/FooConfigVersion.cmake DESTINATION ${LIB_INSTALL_DIR}/Foo/cmake )

With a FooConfig.cmake.in:

set(FOO_VERSION x.y.z) ... @PACKAGE_INIT@ ... set_and_check(FOO_INCLUDE_DIR "@PACKAGE_INCLUDE_INSTALL_DIR@") set_and_check(FOO_SYSCONFIG_DIR "@PACKAGE_SYSCONFIG_INSTALL_DIR@")

check_required_components(Foo)

CMakeParseArguments

CMAKE_PARSE_ARGUMENTS(<prefix> <options> <one_value_keywords> <multi_value_keywords> args...)

CMAKE_PARSE_ARGUMENTS() is intended to be used in macros or functions for parsing the arguments given to that macro or func- tion. It processes the arguments and defines a set of variables which hold the values of the respective options.

The <options> argument contains all options for the respective macro, i.e. keywords which can be used when calling the macro without any value following, like e.g. the OPTIONAL keyword of the install() command.

The <one_value_keywords> argument contains all keywords for this macro which are followed by one value, like e.g. DESTINATION keyword of the install() command.

The <multi_value_keywords> argument contains all keywords for this macro which can be followed by more than one value, like e.g. the TARGETS or FILES keywords of the install() command.

When done, CMAKE_PARSE_ARGUMENTS() will have defined for each of the keywords listed in <options>, <one_value_keywords> and <multi_value_keywords> a variable composed of the given <prefix> followed by "_" and the name of the respective keyword. These variables will then hold the respective value from the argument list. For the <options> keywords this will be TRUE or FALSE.

All remaining arguments are collected in a variable <pre- fix>_UNPARSED_ARGUMENTS, this can be checked afterwards to see whether your macro was called with unrecognized parameters.

As an example here a my_install() macro, which takes similar arguments as the real install() command:

function(MY_INSTALL) set(options OPTIONAL FAST) set(oneValueArgs DESTINATION RENAME) set(multiValueArgs TARGETS CONFIGURATIONS) cmake_parse_arguments(MY_INSTALL "${options}" "${oneValueArgs}" "${multiValueArgs}" ${ARGN} ) ...

Assume my_install() has been called like this:

my_install(TARGETS foo bar DESTINATION bin OPTIONAL blub)

After the cmake_parse_arguments() call the macro will have set the following variables:

MY_INSTALL_OPTIONAL = TRUE MY_INSTALL_FAST = FALSE (this option was not used when calling my_install() MY_INSTALL_DESTINATION = "bin" MY_INSTALL_RENAME = "" (was not used) MY_INSTALL_TARGETS = "foo;bar" MY_INSTALL_CONFIGURATIONS = "" (was not used) MY_INSTALL_UNPARSED_ARGUMENTS = "blub" (no value expected after "OPTIONAL"

You can then continue and process these variables.

Keywords terminate lists of values, e.g. if directly after a one_value_keyword another recognized keyword follows, this is interpreted as the beginning of the new option. E.g. my_install(TARGETS foo DESTINATION OPTIONAL) would result in MY_INSTALL_DESTINATION set to "OPTIONAL", but MY_INSTALL_DESTI- NATION would be empty and MY_INSTALL_OPTIONAL would be set to TRUE therefor.

CMakePrintHelpers Convenience macros for printing properties and variables, useful e.g. for debugging.

CMAKE_PRINT_PROPERTIES([TARGETS target1 .. targetN]

[SOURCES source1 .. sourceN] [DIRECTORIES dir1 .. dirN] [TESTS test1 .. testN] [CACHE_ENTRIES entry1 .. entryN] PROPERTIES prop1 .. propN )

This macro prints the values of the properties of the given tar- gets, source files, directories, tests or cache entries. Exactly one of the scope keywords must be used. Example:

cmake_print_properties(TARGETS foo bar PROPERTIES LOCATION INTERFACE_INCLUDE_DIRS)

This will print the LOCATION and INTERFACE_INCLUDE_DIRS proper- ties for both targets foo and bar.

CMAKE_PRINT_VARIABLES(var1 var2 .. varN)

This macro will print the name of each variable followed by its value. Example:

cmake_print_variables(CMAKE_C_COMPILER CMAKE_MAJOR_VERSION THIS_ONE_DOES_NOT_EXIST)

Gives:

-- CMAKE_C_COMPILER="/usr/bin/gcc" ; CMAKE_MAJOR_VERSION="2" ; THIS_ONE_DOES_NOT_EXIST=""

CMakePrintSystemInformation print system information

This file can be used for diagnostic purposes just include it in a project to see various internal CMake variables.

CMakePushCheckState

This module defines three macros: CMAKE_PUSH_CHECK_STATE() CMAKE_POP_CHECK_STATE() and CMAKE_RESET_CHECK_STATE() These macros can be used to save, restore and reset (i.e., clear con- tents) the state of the variables CMAKE_REQUIRED_FLAGS, CMAKE_REQUIRED_DEFINITIONS, CMAKE_REQUIRED_LIBRARIES and CMAKE_REQUIRED_INCLUDES used by the various Check-files coming with CMake, like e.g. check_function_exists() etc. The variable contents are pushed on a stack, pushing multiple times is sup- ported. This is useful e.g. when executing such tests in a Find-module, where they have to be set, but after the Find-mod- ule has been executed they should have the same value as they had before.

CMAKE_PUSH_CHECK_STATE() macro receives optional argument RESET. Whether its specified, CMAKE_PUSH_CHECK_STATE() will set all CMAKE_REQUIRED_* variables to empty values, same as CMAKE_RESET_CHECK_STATE() call will do.

Usage:

cmake_push_check_state(RESET) set(CMAKE_REQUIRED_DEFINITIONS -DSOME_MORE_DEF) check_function_exists(...) cmake_reset_check_state() set(CMAKE_REQUIRED_DEFINITIONS -DANOTHER_DEF) check_function_exists(...) cmake_pop_check_state()

CMakeVerifyManifest

CMakeVerifyManifest.cmake

This script is used to verify that embeded manifests and side by side manifests for a project match. To run this script, cd to a directory and run the script with cmake -P. On the command line you can pass in versions that are OK even if not found in the .manifest files. For example, cmake -Dallow_versions=8.0.50608.0 -PCmakeVerifyManifest.cmake could be used to allow an embeded manifest of 8.0.50608.0 to be used in a project even if that version was not found in the .manifest file.

CPack Build binary and source package installers.

The CPack module generates binary and source installers in a variety of formats using the cpack program. Inclusion of the CPack module adds two new targets to the resulting makefiles, package and package_source, which build the binary and source installers, respectively. The generated binary installers con- tain everything installed via CMake s INSTALL command (and the deprecated INSTALL_FILES, INSTALL_PROGRAMS, and INSTALL_TARGETS commands).

For certain kinds of binary installers (including the graphical installers on Mac OS X and Windows), CPack generates installers that allow users to select individual application components to install. See CPackComponent module for that.

The CPACK_GENERATOR variable has different meanings in different contexts. In your CMakeLists.txt file, CPACK_GENERATOR is a *list of generators*: when run with no other arguments, CPack will iterate over that list and produce one package for each generator. In a CPACK_PROJECT_CONFIG_FILE, though, CPACK_GENERA- TOR is a *string naming a single generator*. If you need per-cpack- generator logic to control *other* cpack settings, then you need a CPACK_PROJECT_CONFIG_FILE.

The CMake source tree itself contains a CPACK_PROJECT_CON- FIG_FILE. See the top level file CMakeCPackOptions.cmake.in for an example.

If set, the CPACK_PROJECT_CONFIG_FILE is included automatically on a per-generator basis. It only need contain overrides.

Heres how it works:

- cpack runs - it includes CPackConfig.cmake - it iterates over the generators listed in that files CPACK_GENERATOR list variable (unless told to use just a specific one via -G on the command line...)

- foreach generator, it then - sets CPACK_GENERATOR to the one currently being iterated - includes the CPACK_PROJECT_CONFIG_FILE - produces the package for that generator

This is the key: For each generator listed in CPACK_GENERATOR in CPackConfig.cmake, cpack will *reset* CPACK_GENERATOR internally to *the one currently being used* and then include the CPACK_PROJECT_CONFIG_FILE.

Before including this CPack module in your CMakeLists.txt file, there are a variety of variables that can be set to customize the resulting installers. The most commonly-used variables are:

CPACK_PACKAGE_NAME - The name of the package (or application). If not specified, defaults to the project name.

CPACK_PACKAGE_VENDOR - The name of the package vendor. (e.g., "Kitware").

CPACK_PACKAGE_DIRECTORY - The directory in which CPack is doing its packaging. If it is not set then this will default (internally) to the build dir. This variable may be defined in CPack config file or from the cpack command line option "-B". If set the command line option override the value found in the config file.

CPACK_PACKAGE_VERSION_MAJOR - Package major Version

CPACK_PACKAGE_VERSION_MINOR - Package minor Version

CPACK_PACKAGE_VERSION_PATCH - Package patch Version

CPACK_PACKAGE_DESCRIPTION_FILE - A text file used to describe the project. Used, for example, the introduction screen of a CPack-generated Windows installer to describe the project.

CPACK_PACKAGE_DESCRIPTION_SUMMARY - Short description of the project (only a few words).

CPACK_PACKAGE_FILE_NAME - The name of the package file to generate, not including the extension. For example, cmake-2.6.1-Linux-i686. The default value is

${CPACK_PACKAGE_NAME}-${CPACK_PACKAGE_VERSION}-${CPACK_SYSTEM_NAME}.

CPACK_PACKAGE_INSTALL_DIRECTORY - Installation directory on the target system. This may be used by some CPack generators like NSIS to create an installation directory e.g., "CMake 2.5" below the installation prefix. All installed element will be put inside this directory.

CPACK_PACKAGE_ICON - A branding image that will be displayed inside the installer (used by GUI installers).

CPACK_PROJECT_CONFIG_FILE - CPack-time project CPack configuration file. This file included at cpack time, once per generator after CPack has set CPACK_GENERATOR to the actual generator being used. It allows per-generator setting of CPACK_* variables at cpack time.

CPACK_RESOURCE_FILE_LICENSE - License to be embedded in the installer. It will typically be displayed to the user by the produced installer (often with an explicit "Accept" button, for graphical installers) prior to installation. This license file is NOT added to installed file but is used by some CPack generators like NSIS. If you want to install a license file (may be the same as this one) along with your project you must add an appropriate CMake INSTALL command in your CMakeLists.txt.

CPACK_RESOURCE_FILE_README - ReadMe file to be embedded in the installer. It typically describes in some detail the purpose of the project during the installation. Not all CPack generators uses this file.

CPACK_RESOURCE_FILE_WELCOME - Welcome file to be embedded in the installer. It welcomes users to this installer. Typically used in the graphical installers on Windows and Mac OS X.

CPACK_MONOLITHIC_INSTALL - Disables the component-based installation mechanism. When set the component specification is ignored and all installed items are put in a single "MONOLITHIC" package. Some CPack generators do monolithic packaging by default and may be asked to do component packaging by setting CPACK_<GENNAME>_COMPONENT_INSTALL to 1/TRUE.

CPACK_GENERATOR - List of CPack generators to use. If not specified, CPack will create a set of options CPACK_BINARY_<GENNAME> (e.g., CPACK_BINARY_NSIS) allowing the user to enable/disable individual generators. This variable may be used on the command line as well as in:

cpack -D CPACK_GENERATOR="ZIP;TGZ" /path/to/build/tree

CPACK_OUTPUT_CONFIG_FILE - The name of the CPack binary configuration file. This file is the CPack configuration generated by the CPack module for binary installers. Defaults to CPackConfig.cmake.

CPACK_PACKAGE_EXECUTABLES - Lists each of the executables and associated text label to be used to create Start Menu shortcuts. For example, setting this to the list ccmake;CMake will create a shortcut named "CMake" that will execute the installed executable ccmake. Not all CPack generators use it (at least NSIS and OSXX11 do).

CPACK_STRIP_FILES - List of files to be stripped. Starting with CMake 2.6.0 CPACK_STRIP_FILES will be a boolean variable which enables stripping of all files (a list of files evaluates to TRUE in CMake, so this change is compatible).

The following CPack variables are specific to source packages, and will not affect binary packages:

CPACK_SOURCE_PACKAGE_FILE_NAME - The name of the source package. For example cmake-2.6.1.

CPACK_SOURCE_STRIP_FILES - List of files in the source tree that will be stripped. Starting with CMake 2.6.0 CPACK_SOURCE_STRIP_FILES will be a boolean variable which enables stripping of all files (a list of files evaluates to TRUE in CMake, so this change is compatible).

CPACK_SOURCE_GENERATOR - List of generators used for the source packages. As with CPACK_GENERATOR, if this is not specified then CPack will create a set of options (e.g., CPACK_SOURCE_ZIP) allowing users to select which packages will be generated.

CPACK_SOURCE_OUTPUT_CONFIG_FILE - The name of the CPack source configuration file. This file is the CPack configuration generated by the CPack module for source installers. Defaults to CPackSourceConfig.cmake.

CPACK_SOURCE_IGNORE_FILES - Pattern of files in the source tree that wont be packaged when building a source package. This is a list of regular expression patterns (that must be properly escaped), e.g., /CVS/;/\.svn/;\.swp$;\.#;/#;.*~;cscope.*

The following variables are for advanced uses of CPack:

CPACK_CMAKE_GENERATOR - What CMake generator should be used if the project is CMake project. Defaults to the value of CMAKE_GENERATOR few users will want to change this setting.

CPACK_INSTALL_CMAKE_PROJECTS - List of four values that specify what project to install. The four values are: Build directory, Project Name, Project Component, Directory. If omitted, CPack will build an installer that installers everything.

CPACK_SYSTEM_NAME - System name, defaults to the value of ${CMAKE_SYSTEM_NAME}.

CPACK_PACKAGE_VERSION - Package full version, used internally. By default, this is built from CPACK_PACKAGE_VERSION_MAJOR, CPACK_PACKAGE_VERSION_MINOR, and CPACK_PACKAGE_VERSION_PATCH.

CPACK_TOPLEVEL_TAG - Directory for the installed files.

CPACK_INSTALL_COMMANDS - Extra commands to install components.

CPACK_INSTALLED_DIRECTORIES - Extra directories to install.

CPACK_PACKAGE_INSTALL_REGISTRY_KEY - Registry key used when installing this project. This is only used by installer for Windows. The default value is based on the installation directory. CPACK_CREATE_DESKTOP_LINKS - List of desktop links to create.

CPackBundle CPack Bundle generator (Mac OS X) specific options

Installers built on Mac OS X using the Bundle generator use the aforementioned DragNDrop (CPACK_DMG_xxx) variables, plus the following Bundle-specific parameters (CPACK_BUNDLE_xxx).

CPACK_BUNDLE_NAME - The name of the generated bundle. This appears in the OSX finder as the bundle name. Required.

CPACK_BUNDLE_PLIST - Path to an OSX plist file that will be used for the generated bundle. This assumes that the caller has generated or specified their own Info.plist file. Required.

CPACK_BUNDLE_ICON - Path to an OSX icon file that will be used as the icon for the generated bundle. This is the icon that appears in the OSX finder for the bundle, and in the OSX dock when the bundle is opened. Required.

CPACK_BUNDLE_STARTUP_COMMAND - Path to a startup script. This is a path to an executable or script that will be run whenever an end-user double-clicks the generated bundle in the OSX Finder. Optional.

CPackComponent Build binary and source package installers

The CPackComponent module is the module which handles the compo- nent part of CPack. See CPack module for general information about CPack.

For certain kinds of binary installers (including the graphical installers on Mac OS X and Windows), CPack generates installers that allow users to select individual application components to install. The contents of each of the components are identified by the COMPONENT argument of CMake s INSTALL command. These com- ponents can be annotated with user-friendly names and descrip- tions, inter-component dependencies, etc., and grouped in vari- ous ways to customize the resulting installer. See the cpack_add_* commands, described below, for more information about component-specific installations.

Component-specific installation allows users to select specific sets of components to install during the install process. Installation components are identified by the COMPONENT argument of CMake s INSTALL commands, and should be further described by the following CPack commands:

CPACK_COMPONENTS_ALL - The list of component to install.

The default value of this variable is computed by CPack and con- tains all components defined by the project. The user may set it to only include the specified components.

CPACK_<GENNAME>_COMPONENT_INSTALL - Enable/Disable component install for CPack generator <GENNAME>.

Each CPack Generator (RPM, DEB, ARCHIVE, NSIS, DMG, etc...) has a legacy default behavior. e.g. RPM builds monolithic whereas NSIS builds component. One can change the default behavior by setting this variable to 0/1 or OFF/ON.

CPACK_COMPONENTS_GROUPING - Specify how components are grouped for multi-package component-aware CPack generators.

Some generators like RPM or ARCHIVE family (TGZ, ZIP, ...) gen- erates several packages files when asked for component packaging. They group the component differently depending on the value of this variable:

- ONE_PER_GROUP (default): creates one package file per component group - ALL_COMPONENTS_IN_ONE : creates a single package with all (requested) component - IGNORE : creates one package per component, i.e. IGNORE component group

One can specify different grouping for different CPack generator by using a CPACK_PROJECT_CONFIG_FILE.

CPACK_COMPONENT_<compName>_DISPLAY_NAME - The name to be displayed for a component. CPACK_COMPONENT_<compName>_DESCRIPTION - The description of a component. CPACK_COMPONENT_<compName>_GROUP - The group of a component. CPACK_COMPONENT_<compName>_DEPENDS - The dependencies (list of components) on which this component depends. CPACK_COMPONENT_<compName>_REQUIRED - True is this component is required.

cpack_add_component - Describes a CPack installation component named by the COMPONENT argument to a CMake INSTALL command.

cpack_add_component(compname [DISPLAY_NAME name] [DESCRIPTION description] [HIDDEN | REQUIRED | DISABLED ] [GROUP group] [DEPENDS comp1 comp2 ... ] [INSTALL_TYPES type1 type2 ... ] [DOWNLOADED] [ARCHIVE_FILE filename])

The cmake_add_component command describes an installation compo- nent, which the user can opt to install or remove as part of the graphical installation process. compname is the name of the com- ponent, as provided to the COMPONENT argument of one or more CMake INSTALL commands.

DISPLAY_NAME is the displayed name of the component, used in graphical installers to display the component name. This value can be any string.

DESCRIPTION is an extended description of the component, used in graphical installers to give the user additional information about the component. Descriptions can span multiple lines using "0 as the line separator. Typically, these descriptions should be no more than a few lines long.

HIDDEN indicates that this component will be hidden in the graphical installer, so that the user cannot directly change whether it is installed or not.

REQUIRED indicates that this component is required, and there- fore will always be installed. It will be visible in the graphi- cal installer, but it cannot be unselected. (Typically, required components are shown greyed out).

DISABLED indicates that this component should be disabled (unse- lected) by default. The user is free to select this component for installation, unless it is also HIDDEN.

DEPENDS lists the components on which this component depends. If this component is selected, then each of the components listed must also be selected. The dependency information is encoded within the installer itself, so that users cannot install incon- sistent sets of components.

GROUP names the component group of which this component is a part. If not provided, the component will be a standalone compo- nent, not part of any component group. Component groups are described with the cpack_add_component_group command, detailed below.

INSTALL_TYPES lists the installation types of which this compo- nent is a part. When one of these installations types is selected, this component will automatically be selected. Instal- lation types are described with the cpack_add_install_type com- mand, detailed below.

DOWNLOADED indicates that this component should be downloaded on-the-fly by the installer, rather than packaged in with the installer itself. For more information, see the cpack_config- ure_downloads command.

ARCHIVE_FILE provides a name for the archive file created by CPack to be used for downloaded components. If not supplied, CPack will create a file with some name based on CPACK_PACK- AGE_FILE_NAME and the name of the component. See cpack_config- ure_downloads for more information.

cpack_add_component_group - Describes a group of related CPack installation components.

cpack_add_component_group(groupname [DISPLAY_NAME name] [DESCRIPTION description] [PARENT_GROUP parent] [EXPANDED] [BOLD_TITLE])

The cpack_add_component_group describes a group of installation components, which will be placed together within the listing of options. Typically, component groups allow the user to select/deselect all of the components within a single group via a single group-level option. Use component groups to reduce the complexity of installers with many options. groupname is an arbitrary name used to identify the group in the GROUP argument of the cpack_add_component command, which is used to place a component in a group. The name of the group must not conflict with the name of any component.

DISPLAY_NAME is the displayed name of the component group, used in graphical installers to display the component group name. This value can be any string.

DESCRIPTION is an extended description of the component group, used in graphical installers to give the user additional infor- mation about the components within that group. Descriptions can span multiple lines using "0 as the line separator. Typically, these descriptions should be no more than a few lines long.

PARENT_GROUP, if supplied, names the parent group of this group. Parent groups are used to establish a hierarchy of groups, pro- viding an arbitrary hierarchy of groups.

EXPANDED indicates that, by default, the group should show up as "expanded", so that the user immediately sees all of the compo- nents within the group. Otherwise, the group will initially show up as a single entry.

BOLD_TITLE indicates that the group title should appear in bold, to call the users attention to the group.

cpack_add_install_type - Add a new installation type containing a set of predefined component selections to the graphical installer.

cpack_add_install_type(typename [DISPLAY_NAME name])

The cpack_add_install_type command identifies a set of prese- lected components that represents a common use case for an application. For example, a "Developer" install type might include an application along with its header and library files, while an "End user" install type might just include the applica- tion s executable. Each component identifies itself with one or more install types via the INSTALL_TYPES argument to cpack_add_component.

DISPLAY_NAME is the displayed name of the install type, which will typically show up in a drop-down box within a graphical installer. This value can be any string.

cpack_configure_downloads - Configure CPack to download selected components on-the-fly as part of the installation process.

cpack_configure_downloads(site [UPLOAD_DIRECTORY dirname] [ALL] [ADD_REMOVE|NO_ADD_REMOVE])

The cpack_configure_downloads command configures installa- tion-time downloads of selected components. For each downloadable component, CPack will create an archive containing the contents of that component, which should be uploaded to the given site. When the user selects that component for installa- tion, the installer will download and extract the component in place. This feature is useful for creating small installers that only download the requested components, saving bandwidth. Addi- tionally, the installers are small enough that they will be installed as part of the normal installation process, and the "Change" button in Windows Add/Remove Programs control panel will allow one to add or remove parts of the application after the original installation. On Windows, the downloaded-components functionality requires the ZipDLL plug-in for NSIS, available at:

http://nsis.sourceforge.net/ZipDLL_plug-in

On Mac OS X, installers that download components on-the-fly can only be built and installed on system using Mac OS X 10.5 or later.

The site argument is a URL where the archives for downloadable components will reside, e.g., http://www.cmake.org/files/2.6.1/installer/ All of the archives produced by CPack should be uploaded to that location.

UPLOAD_DIRECTORY is the local directory where CPack will create the various archives for each of the components. The contents of this directory should be uploaded to a location accessible by the URL given in the site argument. If omitted, CPack will use the directory CPackUploads inside the CMake binary directory to store the generated archives.

The ALL flag indicates that all components be downloaded. Other- wise, only those components explicitly marked as DOWNLOADED or that have a specified ARCHIVE_FILE will be downloaded. Addition- ally, the ALL option implies ADD_REMOVE (unless NO_ADD_REMOVE is specified).

ADD_REMOVE indicates that CPack should install a copy of the installer that can be called from Windows Add/Remove Programs dialog (via the "Modify" button) to change the set of installed components. NO_ADD_REMOVE turns off this behavior. This option is ignored on Mac OS X.

CPackCygwin Cygwin CPack generator (Cygwin).

The following variable is specific to installers build on and/or for Cygwin:

CPACK_CYGWIN_PATCH_NUMBER - The Cygwin patch number. FIXME: This documentation is incomplete. CPACK_CYGWIN_PATCH_FILE - The Cygwin patch file. FIXME: This documentation is incomplete. CPACK_CYGWIN_BUILD_SCRIPT - The Cygwin build script. FIXME: This documentation is incomplete.

CPACK_DMG_FORMAT - The disk image format. Common values are UDRO (UDIF read-only), UDZO (UDIF zlib-compressed) or UDBZ (UDIF bzip2-compressed). Refer to hdiutil(1) for more information on other available formats.

CPACK_DMG_DS_STORE - Path to a custom DS_Store file. This .DS_Store file e.g. can be used to specify the Finder window position/geometry and layout (such as hidden toolbars, placement of the icons etc.). This file has to be generated by the Finder (either manually or through OSA-script) using a normal folder from which the .DS_Store file can then be extracted.

CPACK_DMG_BACKGROUND_IMAGE - Path to a background image file. This file will be used as the background for the Finder Window when the disk image is opened. By default no background image is set. The background image is applied after applying the custom .DS_Store file.

CPACK_COMMAND_HDIUTIL - Path to the hdiutil(1) command used to operate on disk image files on Mac OS X. This variable can be used to override the automatically detected command (or specify its location if the auto-detection fails to find it.)

CPACK_COMMAND_SETFILE - Path to the SetFile(1) command used to set extended attributes on files and directories on Mac OS X. This variable can be used to override the automatically detected command (or specify its location if the auto-detection fails to find it.)

CPACK_COMMAND_REZ - Path to the Rez(1) command used to compile resources on Mac OS X. This variable can be used to override the automatically detected command (or specify its location if the auto-detection fails to find it.)

The following variable is specific to installers built on Mac OS X using PackageMaker:

CPACK_OSX_PACKAGE_VERSION - The version of Mac OS X that the resulting PackageMaker archive should be compatible with. Different versions of Mac OS X support different features. For example, CPack can only build component-based installers for Mac OS X 10.4 or newer, and can only build installers that download component son-the-fly for Mac OS X 10.5 or newer. If left blank, this value will be set to the minimum version of Mac OS X that supports the requested features. Set this variable to some value (e.g., 10.4) only if you want to guarantee that your installer will work on that version of Mac OS X, and dont mind missing extra features available in the installer shipping with later versions of Mac OS X.

CPackRPM The builtin (binary) CPack RPM generator (Unix only)

CPackRPM may be used to create RPM package using CPack. CPackRPM is a CPack generator thus it uses the CPACK_XXX variables used by CPack : http://www.cmake.org/Wiki/CMake:CPackConfiguration

However CPackRPM has specific features which are controlled by the specifics CPACK_RPM_XXX variables. CPackRPM is a component aware generator so when CPACK_RPM_COMPONENT_INSTALL is ON some more CPACK_RPM_<ComponentName>_XXXX variables may be used in order to have component specific values. Note however that <com- ponentName> refers to the **grouping name**. This may be either a component name or a component GROUP name. Usually those vars correspond to RPM spec file entities, one may find information about spec files here http://www.rpm.org/wiki/Docs. Youll find a detailed usage of CPackRPM on the wiki:

http://www.cmake.org/Wiki/CMake:CPackPackageGenerators#RPM_.28Unix_Only.29

However as a handy reminder here comes the list of specific variables:

CPACK_RPM_PACKAGE_SUMMARY - The RPM package summary. Mandatory : YES Default : CPACK_PACKAGE_DESCRIPTION_SUMMARY CPACK_RPM_PACKAGE_NAME - The RPM package name. Mandatory : YES Default : CPACK_PACKAGE_NAME CPACK_RPM_PACKAGE_VERSION - The RPM package version.

Mandatory : NO Default : - This may be set to "noarch" if you know you are building a noarch package. CPACK_RPM_PACKAGE_RELEASE - The RPM package release. Mandatory : YES Default : 1 This is the numbering of the RPM package itself, i.e. the version of the packaging and not the version of the content (see CPACK_RPM_PACKAGE_VERSION). One may change the default value if the previous packaging was buggy and/or you want to put here a fancy Linux distro specific numbering. CPACK_RPM_PACKAGE_LICENSE - The RPM package license policy. Mandatory : YES Default : "unknown" CPACK_RPM_PACKAGE_GROUP - The RPM package group. Mandatory : YES Default : "unknown" CPACK_RPM_PACKAGE_VENDOR - The RPM package vendor.

Mandatory : YES Default : CPACK_PACKAGE_DESCRIPTION_FILE if set or "no package description available" CPACK_RPM_COMPRESSION_TYPE - RPM compression type. Mandatory : NO Default : - May be used to override RPM compression type to be used to build the RPM. For example some Linux distribution now default to lzma or xz compression whereas older cannot use such RPM. Using this one can enforce compression type to be used. Possible value are: lzma, xz, bzip2 and gzip. CPACK_RPM_PACKAGE_REQUIRES - RPM spec requires field. Mandatory : NO Default : - May be used to set RPM dependencies (requires). Note that you must enclose the complete requires string between quotes, for example: set(CPACK_RPM_PACKAGE_REQUIRES "python >= 2.5.0, cmake >= 2.8") The required package list of an RPM file could be printed with rpm -qp --requires file.rpm CPACK_RPM_PACKAGE_SUGGESTS - RPM spec suggest field. Mandatory : NO Default : - May be used to set weak RPM dependencies (suggests). Note that you must enclose the complete requires string between quotes. CPACK_RPM_PACKAGE_PROVIDES - RPM spec provides field. Mandatory : NO Default : - May be used to set RPM dependencies (provides). The provided package list of an RPM file could be printed with rpm -qp --provides file.rpm CPACK_RPM_PACKAGE_OBSOLETES - RPM spec obsoletes field. Mandatory : NO Default : - May be used to set RPM packages that are obsoleted by this one. CPACK_RPM_PACKAGE_RELOCATABLE - build a relocatable RPM. Mandatory : NO Default : CPACK_PACKAGE_RELOCATABLE If this variable is set to TRUE or ON CPackRPM will try to build a relocatable RPM package. A relocatable RPM may be installed using rpm --prefix or --relocate in order to install it at an alternate place see rpm(8). Note that currently this may fail if CPACK_SET_DESTDIR is set to ON. If CPACK_SET_DESTDIR is set then you will get a warning message but if there is file installed with absolute path youll get unexpected behavior. CPACK_RPM_SPEC_INSTALL_POST - [deprecated]. Mandatory : NO Default : - This way of specifying post-install script is deprecated use CPACK_RPM_POST_INSTALL_SCRIPT_FILE May be used to set an RPM post-install command inside the spec file. For example setting it to "/bin/true" may be used to prevent rpmbuild to strip binaries. CPACK_RPM_SPEC_MORE_DEFINE - RPM extended spec definitions lines. Mandatory : NO Default : - May be used to add any %define lines to the generated spec file. CPACK_RPM_PACKAGE_DEBUG - Toggle CPackRPM debug output. Mandatory : NO Default : - May be set when invoking cpack in order to trace debug information during CPack RPM run. For example you may launch CPack like this cpack -D CPACK_RPM_PACKAGE_DEBUG=1 -G RPM CPACK_RPM_USER_BINARY_SPECFILE - A user provided spec file. Mandatory : NO Default : - May be set by the user in order to specify a USER binary spec file to be used by CPackRPM instead of generating the file. The specified file will be processed by configure_file( @ONLY). One can provide a component specific file by setting CPACK_RPM_<componentName>_USER_BINARY_SPECFILE. CPACK_RPM_GENERATE_USER_BINARY_SPECFILE_TEMPLATE - Spec file template. Mandatory : NO Default : - If set CPack will generate a template for USER specified binary spec file and stop with an error. For example launch CPack like this cpack -D CPACK_RPM_GENERATE_USER_BINARY_SPECFILE_TEMPLATE=1 -G RPM The user may then use this file in order to hand-craft is own binary spec file which may be used with CPACK_RPM_USER_BINARY_SPECFILE. CPACK_RPM_PRE_INSTALL_SCRIPT_FILE CPACK_RPM_PRE_UNINSTALL_SCRIPT_FILE Mandatory : NO Default : - May be used to embed a pre (un)installation script in the spec file. The refered script file(s) will be read and directly put after the %pre or %preun section If CPACK_RPM_COMPONENT_INSTALL is set to ON the (un)install script for each component can be overridden with CPACK_RPM_<COMPONENT>_PRE_INSTALL_SCRIPT_FILE and CPACK_RPM_<COMPONENT>_PRE_UNINSTALL_SCRIPT_FILE One may verify which scriptlet has been included with rpm -qp --scripts package.rpm CPACK_RPM_POST_INSTALL_SCRIPT_FILE CPACK_RPM_POST_UNINSTALL_SCRIPT_FILE Mandatory : NO Default : - May be used to embed a post (un)installation script in the spec file. The refered script file(s) will be read and directly put after the %post or %postun section If CPACK_RPM_COMPONENT_INSTALL is set to ON the (un)install script for each component can be overridden with CPACK_RPM_<COMPONENT>_POST_INSTALL_SCRIPT_FILE and CPACK_RPM_<COMPONENT>_POST_UNINSTALL_SCRIPT_FILE One may verify which scriptlet has been included with rpm -qp --scripts package.rpm CPACK_RPM_USER_FILELIST CPACK_RPM_<COMPONENT>_USER_FILELIST Mandatory : NO Default : - May be used to explicitly specify %(<directive>) file line in the spec file. Like %config(noreplace) or any other directive that be found in the %files section. Since CPackRPM is generating the list of files (and directories) the user specified files of the CPACK_RPM_<COMPONENT>_USER_FILELIST list will be removed from the generated list. CPACK_RPM_CHANGELOG_FILE - RPM changelog file. Mandatory : NO Default : - May be used to embed a changelog in the spec file. The refered file will be read and directly put after the %changelog section. CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST - list of path to be excluded. Mandatory : NO Default : /etc /etc/init.d /usr /usr/share /usr/share/doc /usr/bin /usr/lib /usr/lib64 /usr/include May be used to exclude path (directories or files) from the auto-generated list of paths discovered by CPack RPM. The defaut value contains a reasonable set of values if the variable is not defined by the user. If the variable is defined by the user then CPackRPM will NOT any of the default path. If you want to add some path to the default list then you can use CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST_ADDITION variable. CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST_ADDITION - additional list of path to be excluded. Mandatory : NO Default : - May be used to add more exclude path (directories or files) from the initial default list of excluded paths. See CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST.

CPackWIX CPack WiX generator specific options

The following variables are specific to the installers built on Windows using WiX.

CPACK_WIX_UPGRADE_GUID - Upgrade GUID (Product/@UpgradeCode)

Will be automatically generated unless explicitly provided.

It should be explicitly set to a constant generated gloabally unique identifier (GUID) to allow your installers to replace existing installations that use the same GUID.

You may for example explicitly set this variable in your CMake- Lists.txt to the value that has been generated per default. You should not use GUIDs that you did not generate yourself or which may belong to other projects.

A GUID shall have the following fixed length syntax: XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX

(each X represents an uppercase hexadecimal digit) CPACK_WIX_PRODUCT_GUID - Product GUID (Product/@Id)

Will be automatically generated unless explicitly provided.

If explicitly provided this will set the Product Id of your installer.

The installer will abort if it detects a pre-existing installa- tion that uses the same GUID.

The GUID shall use the syntax described for CPACK_WIX_UPGRADE_GUID.

CPACK_WIX_LICENSE_RTF - RTF License File

If CPACK_RESOURCE_FILE_LICENSE has an .rtf extension it is used as-is.

If CPACK_RESOURCE_FILE_LICENSE has an .txt extension it is implicitly converted to RTF by the WiX Generator.

With CPACK_WIX_LICENSE_RTF you can override the license file used by the WiX Generator in case CPACK_RESOURCE_FILE_LICENSE is in an unsupported format or the .txt -> .rtf conversion does not work as expected.

CPACK_WIX_PRODUCT_ICON - The Icon shown next to the program name in Add/Remove programs.

If set, this icon is used in place of the default icon.

CPACK_WIX_UI_BANNER - The bitmap will appear at the top of all installer pages other than the welcome and completion dialogs.

If set, this image will replace the default banner image.

This image must be 493 by 58 pixels.

CPACK_WIX_UI_DIALOG - Background bitmap used on the welcome and completion dialogs.

If this variable is set, the installer will replace the default dialog image.

This image must be 493 by 312 pixels.

CPACK_WIX_PROGRAM_MENU_FOLDER - Start menu folder name for launcher.

If this variable is not set, it will be initialized with CPACK_PACKAGE_NAME

CPACK_WIX_CULTURES - Language(s) of the installer

Languages are compiled into the WixUI extension library. To use them, simply provide the name of the culture. If you specify more than one culture identifier in a comma or semicolon delim- ited list, the first one that is found will be used. You can find a list of supported languages at: http://wix.source- forge.net/manual-wix3/WixUI_localization.htm

CPACK_WIX_TEMPLATE - Template file for WiX generation

If this variable is set, the specified template will be used to generate the WiX wxs file. This should be used if further cus- tomization of the output is required.

If this variable is not set, the default MSI template included with CMake will be used.

CTest Configure a project for testing with CTest/CDash

Include this module in the top CMakeLists.txt file of a project to enable testing with CTest and dashboard submissions to CDash:

project(MyProject) ... include(CTest)

The module automatically creates a BUILD_TESTING option that selects whether to enable testing support (ON by default). After including the module, use code like

if(BUILD_TESTING) # ... CMake code to create tests ... endif()

to creating tests when testing is enabled.

To enable submissions to a CDash server, create a CTestCon- fig.cmake file at the top of the project with content such as

set(CTEST_PROJECT_NAME "MyProject") set(CTEST_NIGHTLY_START_TIME "01:00:00 UTC") set(CTEST_DROP_METHOD "http") set(CTEST_DROP_SITE "my.cdash.org") set(CTEST_DROP_LOCATION "/submit.php?project=MyProject") set(CTEST_DROP_SITE_CDASH TRUE)

(the CDash server can provide the file to a project administra- tor who configures MyProject ). Settings in the config file are shared by both this CTest module and the CTest command-line tools dashboard script mode (ctest -S).

While building a project for submission to CDash, CTest scans the build output for errors and warnings and reports them with surrounding context from the build log. This generic approach works for all build tools, but does not give details about the command invocation that produced a given problem. One may get more detailed reports by adding

set(CTEST_USE_LAUNCHERS 1)

to the CTestConfig.cmake file. When this option is enabled, the CTest module tells CMakes Makefile generators to invoke every command in the generated build system through a CTest launcher program. (Currently the CTEST_USE_LAUNCHERS option is ignored on non-Makefile generators.) During a manual build each launcher transparently runs the command it wraps. During a CTest-driven build for submission to CDash each launcher reports detailed information when its command fails or warns. (Setting CTEST_USE_LAUNCHERS in CTestConfig.cmake is convenient, but also adds the launcher overhead even for manual builds. One may instead set it in a CTest dashboard script and add it to the CMake cache for the build tree.)

CTestScriptMode

This file is read by ctest in script mode (-S)

CTestUseLaunchers Set the RULE_LAUNCH_* global properties when CTEST_USE_LAUNCHERS is on.

CTestUseLaunchers is automatically included when you include(CTest). However, it is split out into its own module file so projects can use the CTEST_USE_LAUNCHERS functionality independently.

To use launchers, set CTEST_USE_LAUNCHERS to ON in a ctest -S dashboard script, and then also set it in the cache of the con- figured project. Both cmake and ctest need to know the value of it for the launchers to work properly. CMake needs to know in order to generate proper build rules, and ctest, in order to produce the proper error and warning analysis.

For convenience, you may set the ENV variable CTEST_USE_LAUNCH- ERS_DEFAULT in your ctest -S script, too. Then, as long as your CMakeLists uses include(CTest) or include(CTestUseLaunchers), it will use the value of the ENV variable to initialize a CTEST_USE_LAUNCHERS cache variable. This cache variable initial- ization only occurs if CTEST_USE_LAUNCHERS is not already defined.

CheckCCompilerFlag Check whether the C compiler supports a given flag.

CHECK_C_COMPILER_FLAG(<flag> <var>)

<flag> - the compiler flag <var> - variable to store the result

This internally calls the check_c_source_compiles macro and sets CMAKE_REQUIRED_DEFINITIONS to <flag>. See help for CheckCSource- Compiles for a listing of variables that can otherwise modify the build. The result only tells that the compiler does not give an error message when it encounters the flag. If the flag has any effect or even a specific one is beyond the scope of this module.

CHECK_CXX_COMPILER_FLAG(<flag> <var>)

<flag> - the compiler flag <var> - variable to store the result

This internally calls the check_cxx_source_compiles macro and sets CMAKE_REQUIRED_DEFINITIONS to <flag>. See help for Check- CXXSourceCompiles for a listing of variables that can otherwise modify the build. The result only tells that the compiler does not give an error message when it encounters the flag. If the flag has any effect or even a specific one is beyond the scope of this module.

CMAKE_REQUIRED_FLAGS = string of compile command line flags CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar) CMAKE_REQUIRED_INCLUDES = list of include directories CMAKE_REQUIRED_LIBRARIES = list of libraries to link

CheckCXXSymbolExists Check if a symbol exists as a function, variable, or macro in C++

CHECK_CXX_SYMBOL_EXISTS(<symbol> <files> <variable>)

Check that the <symbol> is available after including given header <files> and store the result in a <variable>. Specify the list of files in one argument as a semicolon-separated list. CHECK_CXX_SYMBOL_EXISTS() can be used to check in C++ files, as opposed to CHECK_SYMBOL_EXISTS(), which works only for C.

If the header files define the symbol as a macro it is consid- ered available and assumed to work. If the header files declare the symbol as a function or variable then the symbol must also be available for linking. If the symbol is a type or enum value it will not be recognized (consider using CheckTypeSize or CheckCSourceCompiles).

The following variables may be set before calling this macro to modify the way the check is run:

CMAKE_REQUIRED_FLAGS = string of compile command line flags CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar) CMAKE_REQUIRED_INCLUDES = list of include directories CMAKE_REQUIRED_LIBRARIES = list of libraries to link

CheckFortranFunctionExists macro which checks if the Fortran function exists

CheckLanguage Check if a language can be enabled

Usage:

check_language(<lang>)

where <lang> is a language that may be passed to enable_lan- guage() such as "Fortran". If CMAKE_<lang>_COMPILER is already defined the check does nothing. Otherwise it tries enabling the language in a test project. The result is cached in CMAKE_<lang>_COMPILER as the compiler that was found, or NOT- FOUND if the language cannot be enabled.

Example:

check_language(Fortran) if(CMAKE_Fortran_COMPILER) enable_language(Fortran) else() message(STATUS "No Fortran support") endif()

CheckLibraryExists Check if the function exists.

CHECK_LIBRARY_EXISTS (LIBRARY FUNCTION LOCATION VARIABLE)

LIBRARY - the name of the library you are looking for FUNCTION - the name of the function LOCATION - location where the library should be found VARIABLE - variable to store the result

The following variables may be set before calling this macro to modify the way the check is run:

CMAKE_REQUIRED_FLAGS = string of compile command line flags CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar) CMAKE_REQUIRED_LIBRARIES = list of libraries to link

CheckPrototypeDefinition Check if the protoype we expect is correct.

check_prototype_definition(FUNCTION PROTOTYPE RETURN HEADER VARIABLE)

FUNCTION - The name of the function (used to check if prototype exists) PROTOTYPE- The prototype to check. RETURN - The return value of the function. HEADER - The header files required. VARIABLE - The variable to store the result.

Example:

check_prototype_definition(getpwent_r "struct passwd *getpwent_r(struct passwd *src, char *buf, int buflen)" "NULL" "unistd.h;pwd.h" SOLARIS_GETPWENT_R)

The following variables may be set before calling this macro to modify the way the check is run:

CMAKE_REQUIRED_FLAGS = string of compile command line flags CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar) CMAKE_REQUIRED_INCLUDES = list of include directories CMAKE_REQUIRED_LIBRARIES = list of libraries to link

CheckStructHasMember Check if the given struct or class has the specified member variable

STRUCT - the name of the struct or class you are interested in MEMBER - the member which existence you want to check HEADER - the header(s) where the prototype should be declared VARIABLE - variable to store the result

The following variables may be set before calling this macro to modify the way the check is run:

CMAKE_REQUIRED_FLAGS = string of compile command line flags CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar) CMAKE_REQUIRED_INCLUDES = list of include directories

Example: CHECK_STRUCT_HAS_MEMBER("struct timeval" tv_sec sys/select.h HAVE_TIMEVAL_TV_SEC)

CheckSymbolExists Check if a symbol exists as a function, variable, or macro

CHECK_SYMBOL_EXISTS(<symbol> <files> <variable>)

Check that the <symbol> is available after including given header <files> and store the result in a <variable>. Specify the list of files in one argument as a semicolon-separated list.

If the header files define the symbol as a macro it is consid- ered available and assumed to work. If the header files declare the symbol as a function or variable then the symbol must also be available for linking. If the symbol is a type or enum value it will not be recognized (consider using CheckTypeSize or CheckCSourceCompiles). If the check needs to be done in C++, consider using CHECK_CXX_SYMBOL_EXISTS(), which does the same as CHECK_SYMBOL_EXISTS(), but in C++.

The following variables may be set before calling this macro to modify the way the check is run:

CMAKE_REQUIRED_FLAGS = string of compile command line flags CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar) CMAKE_REQUIRED_INCLUDES = list of include directories CMAKE_REQUIRED_LIBRARIES = list of libraries to link

CheckTypeSize Check sizeof a type

CHECK_TYPE_SIZE(TYPE VARIABLE [BUILTIN_TYPES_ONLY])

Check if the type exists and determine its size. On return, "HAVE_${VARIABLE}" holds the existence of the type, and "${VARI- ABLE}" holds one of the following:

<size> = type has non-zero size <size> "0" = type has arch-dependent size (see below) "" = type does not exist

Furthermore, the variable "${VARIABLE}_CODE" holds C preproces- sor code to define the macro "${VARIABLE}" to the size of the type, or leave the macro undefined if the type does not exist.

The variable "${VARIABLE}" may be "0" when CMAKE_OSX_ARCHITEC- TURES has multiple architectures for building OS X universal binaries. This indicates that the type size varies across archi- tectures. In this case "${VARIABLE}_CODE" contains C preproces- sor tests mapping from each architecture macro to the corre- sponding type size. The list of architecture macros is stored in "${VARIABLE}_KEYS", and the value for each key is stored in "${VARIABLE}-${KEY}".

If the BUILTIN_TYPES_ONLY option is not given, the macro checks for headers <sys/types.h>, <stdint.h>, and <stddef.h>, and saves results in HAVE_SYS_TYPES_H, HAVE_STDINT_H, and HAVE_STDDEF_H. The type size check automatically includes the available head- ers, thus supporting checks of types defined in the headers.

Despite the name of the macro you may use it to check the size of more complex expressions, too. To check e.g. for the size of a struct member you can do something like this:

check_type_size("((struct something*)0)->member" SIZEOF_MEMBER)

The following variables may be set before calling this macro to modify the way the check is run:

CMAKE_REQUIRED_FLAGS = string of compile command line flags CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar) CMAKE_REQUIRED_INCLUDES = list of include directories CMAKE_REQUIRED_LIBRARIES = list of libraries to link CMAKE_EXTRA_INCLUDE_FILES = list of extra headers to include

CheckVariableExists Check if the variable exists.

CHECK_VARIABLE_EXISTS(VAR VARIABLE)

VAR - the name of the variable VARIABLE - variable to store the result

This macro is only for C variables.

The following variables may be set before calling this macro to modify the way the check is run:

CMAKE_REQUIRED_FLAGS = string of compile command line flags CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar) CMAKE_REQUIRED_LIBRARIES = list of libraries to link

Dart Configure a project for testing with CTest or old Dart Tcl Client

This file is the backwards-compatibility version of the CTest module. It supports using the old Dart 1 Tcl client for driving dashboard submissions as well as testing with CTest. This mod- ule should be included in the CMakeLists.txt file at the top of a project. Typical usage:

include(Dart) if(BUILD_TESTING) # ... testing related CMake code ... endif()

The BUILD_TESTING option is created by the Dart module to deter- mine whether testing support should be enabled. The default is ON.

DeployQt4 Functions to help assemble a standalone Qt4 executable.

A collection of CMake utility functions useful for deploying Qt4 executables.

The following functions are provided by this module:

write_qt4_conf resolve_qt4_paths fixup_qt4_executable install_qt4_plugin_path install_qt4_plugin install_qt4_executable

Requires CMake 2.6 or greater because it uses function and PAR- ENT_SCOPE. Also depends on BundleUtilities.cmake.

WRITE_QT4_CONF(<qt_conf_dir> <qt_conf_contents>)

Writes a qt.conf file with the <qt_conf_contents> into <qt_conf_dir>.

RESOLVE_QT4_PATHS(<paths_var> [<executable_path>])

Loop through <paths_var> list and if any dont exist resolve them relative to the <executable_path> (if supplied) or the CMAKE_INSTALL_PREFIX.

FIXUP_QT4_EXECUTABLE(<executable> [<qtplugins> <libs> <dirs> <plugins_dir> <request_qt_conf>])

Copies Qt plugins, writes a Qt configuration file (if needed) and fixes up a Qt4 executable using BundleUtilities so it is standalone and can be drag-and-drop copied to another machine as long as all of the system libraries are compatible.

<executable> should point to the executable to be fixed-up.

<qtplugins> should contain a list of the names or paths of any Qt plugins to be installed.

<libs> will be passed to BundleUtilities and should be a list of any already installed plugins, libraries or executables to also be fixed-up.

<dirs> will be passed to BundleUtilities and should contain and directories to be searched to find library dependencies.

<plugins_dir> allows an custom plugins directory to be used.

<request_qt_conf> will force a qt.conf file to be written even if not needed.

INSTALL_QT4_PLUGIN_PATH(plugin executable copy installed_plugin_path_var <plugins_dir> <component> <configurations>)

Install (or copy) a resolved <plugin> to the default plugins directory (or <plugins_dir>) relative to <executable> and store the result in <installed_plugin_path_var>.

If <copy> is set to TRUE then the plugins will be copied rather than installed. This is to allow this module to be used at CMake time rather than install time.

If <component> is set then anything installed will use this COM- PONENT.

INSTALL_QT4_PLUGIN(plugin executable copy installed_plugin_path_var <plugins_dir> <component>)

Install (or copy) an unresolved <plugin> to the default plugins directory (or <plugins_dir>) relative to <executable> and store the result in <installed_plugin_path_var>. See documentation of INSTALL_QT4_PLUGIN_PATH.

INSTALL_QT4_EXECUTABLE(<executable> [<qtplugins> <libs> <dirs> <plugins_dir> <request_qt_conf> <component>])

Installs Qt plugins, writes a Qt configuration file (if needed) and fixes up a Qt4 executable using BundleUtilities so it is standalone and can be drag-and-drop copied to another machine as long as all of the system libraries are compatible. The exe- cutable will be fixed-up at install time. <component> is the COMPONENT used for bundle fixup and plugin installation. See documentation of FIXUP_QT4_BUNDLE.

Documentation DocumentationVTK.cmake

This file provides support for the VTK documentation framework. It relies on several tools (Doxygen, Perl, etc).

ExternalData Manage data files stored outside source tree

Use this module to unambiguously reference data files stored outside the source tree and fetch them at build time from arbi- trary local and remote content-addressed locations. Functions provided by this module recognize arguments with the syntax "DATA{<name>}" as references to external data, replace them with full paths to local copies of those data, and create build rules to fetch and update the local copies.

The DATA{} syntax is literal and the <name> is a full or rela- tive path within the source tree. The source tree must contain either a real data file at <name> or a "content link" at <name><ext> containing a hash of the real file using a hash algorithm corresponding to <ext>. For example, the argument "DATA{img.png}" may be satisfied by either a real "img.png" file in the current source directory or a "img.png.md5" file contain- ing its MD5 sum.

The ExternalData_Expand_Arguments function evaluates DATA{} references in its arguments and constructs a new list of argu- ments:

ExternalData_Expand_Arguments( <target> # Name of data management target <outVar> # Output variable [args...] # Input arguments, DATA{} allowed )

It replaces each DATA{} reference in an argument with the full path of a real data file on disk that will exist after the <tar- get> builds.

The ExternalData_Add_Test function wraps around the CMake add_test() command but supports DATA{} references in its argu- ments:

ExternalData_Add_Test( <target> # Name of data management target ... # Arguments of add_test(), DATA{} allowed )

It passes its arguments through ExternalData_Expand_Arguments and then invokes add_test() using the results.

The ExternalData_Add_Target function creates a custom target to manage local instances of data files stored externally:

ExternalData_Add_Target( <target> # Name of data management target )

It creates custom commands in the target as necessary to make data files available for each DATA{} reference previously evalu- ated by other functions provided by this module. A list of URL templates must be provided in the variable ExternalData_URL_TEM- PLATES using the placeholders "%(algo)" and "%(hash)" in each template. Data fetch rules try each URL template in order by substituting the hash algorithm name for "%(algo)" and the hash value for "%(hash)".

The following hash algorithms are supported:

%(algo) <ext> Description ------- ----- ----------- MD5 .md5 Message-Digest Algorithm 5, RFC 1321 SHA1 .sha1 US Secure Hash Algorithm 1, RFC 3174 SHA224 .sha224 US Secure Hash Algorithms, RFC 4634 SHA256 .sha256 US Secure Hash Algorithms, RFC 4634 SHA384 .sha384 US Secure Hash Algorithms, RFC 4634 SHA512 .sha512 US Secure Hash Algorithms, RFC 4634

Note that the hashes are used only for unique data identifica- tion and download verification. This is not security software.

Example usage:

include(ExternalData) set(ExternalData_URL_TEMPLATES "file:///local/%(algo)/%(hash)" "http://data.org/%(algo)/%(hash)") ExternalData_Add_Test(MyData NAME MyTest COMMAND MyExe DATA{MyInput.png} ) ExternalData_Add_Target(MyData)

When test "MyTest" runs the "DATA{MyInput.png}" argument will be replaced by the full path to a real instance of the data file "MyInput.png" on disk. If the source tree contains a content link such as "MyInput.png.md5" then the "MyData" target creates a real "MyInput.png" in the build tree.

The DATA{} syntax can be told to fetch a file series using the form "DATA{<name>,:}", where the ":" is literal. If the source tree contains a group of files or content links named like a series then a reference to one member adds rules to fetch all of them. Although all members of a series are fetched, only the file originally named by the DATA{} argument is substituted for it. The default configuration recognizes file series names end- ing with "#.ext", "_#.ext", ".#.ext", or "-#.ext" where "#" is a sequence of decimal digits and ".ext" is any single extension. Configure it with a regex that parses <number> and <suffix> parts from the end of <name>:

ExternalData_SERIES_PARSE = regex of the form (<number>)(<suffix>)$

For more complicated cases set:

ExternalData_SERIES_PARSE = regex with at least two () groups ExternalData_SERIES_PARSE_PREFIX = <prefix> regex group number, if any ExternalData_SERIES_PARSE_NUMBER = <number> regex group number ExternalData_SERIES_PARSE_SUFFIX = <suffix> regex group number

Configure series number matching with a regex that matches the <number> part of series members named <prefix><number><suffix>:

ExternalData_SERIES_MATCH = regex matching <number> in all series members

Note that the <suffix> of a series does not include a hash-algo- rithm extension.

The DATA{} syntax can alternatively match files associated with the named file and contained in the same directory. Associated files may be specified by options using the syntax DATA{<name>,<opt1>,<opt2>,...}. Each option may specify one file by name or specify a regular expression to match file names using the syntax REGEX:<regex>. For example, the arguments

DATA{MyData/MyInput.mhd,MyInput.img} # File pair DATA{MyData/MyFrames00.png,REGEX:MyFrames[0-9]+\.png} # Series

will pass MyInput.mha and MyFrames00.png on the command line but ensure that the associated files are present next to them.

The DATA{} syntax may reference a directory using a trailing slash and a list of associated files. The form DATA{<name>/,<opt1>,<opt2>,...} adds rules to fetch any files in the directory that match one of the associated file options. For example, the argument DATA{MyDataDir/,REGEX:.*} will pass the full path to a MyDataDir directory on the command line and ensure that the directory contains files corresponding to every file or content link in the MyDataDir source directory.

The variable ExternalData_LINK_CONTENT may be set to the name of a supported hash algorithm to enable automatic conversion of real data files referenced by the DATA{} syntax into content links. For each such <file> a content link named "<file><ext>" is created. The original file is renamed to the form ".Exter- nalData_<algo>_<hash>" to stage it for future transmission to one of the locations in the list of URL templates (by means out- side the scope of this module). The data fetch rule created for the content link will use the staged object if it cannot be found using any URL template.

The variable ExternalData_OBJECT_STORES may be set to a list of local directories that store objects using the layout <dir>/%(algo)/%(hash). These directories will be searched first for a needed object. If the object is not available in any store then it will be fetched remotely using the URL templates and added to the first local store listed. If no stores are specified the default is a location inside the build tree.

The variable ExternalData_SOURCE_ROOT may be set to the highest source directory containing any path named by a DATA{} refer- ence. The default is CMAKE_SOURCE_DIR. ExternalData_SOURCE_ROOT and CMAKE_SOURCE_DIR must refer to directories within a single source distribution (e.g. they come together in one tarball).

The variable ExternalData_BINARY_ROOT may be set to the direc- tory to hold the real data files named by expanded DATA{} refer- ences. The default is CMAKE_BINARY_DIR. The directory layout will mirror that of content links under External- Data_SOURCE_ROOT.

Variables ExternalData_TIMEOUT_INACTIVITY and ExternalData_TIME- OUT_ABSOLUTE set the download inactivity and absolute timeouts, in seconds. The defaults are 60 seconds and 300 seconds, respectively. Set either timeout to 0 seconds to disable enforcement.

ExternalProject Create custom targets to build projects in external trees

The ExternalProject_Add function creates a custom target to drive download, update/patch, configure, build, install and test steps of an external project:

ExternalProject_Add(<name> # Name for custom target [DEPENDS projects...] # Targets on which the project depends [PREFIX dir] # Root dir for entire project [LIST_SEPARATOR sep] # Sep to be replaced by ; in cmd lines [TMP_DIR dir] # Directory to store temporary files [STAMP_DIR dir] # Directory to store step timestamps #--Download step-------------- [DOWNLOAD_NAME fname] # File name to store (if not end of URL) [DOWNLOAD_DIR dir] # Directory to store downloaded files [DOWNLOAD_COMMAND cmd...] # Command to download source tree [CVS_REPOSITORY cvsroot] # CVSROOT of CVS repository [CVS_MODULE mod] # Module to checkout from CVS repo [CVS_TAG tag] # Tag to checkout from CVS repo [SVN_REPOSITORY url] # URL of Subversion repo [SVN_REVISION rev] # Revision to checkout from Subversion repo [SVN_USERNAME john ] # Username for Subversion checkout and update [SVN_PASSWORD doe ] # Password for Subversion checkout and update [SVN_TRUST_CERT 1 ] # Trust the Subversion server site certificate [GIT_REPOSITORY url] # URL of git repo [GIT_TAG tag] # Git branch name, commit id or tag [HG_REPOSITORY url] # URL of mercurial repo [HG_TAG tag] # Mercurial branch name, commit id or tag [URL /.../src.tgz] # Full path or URL of source [URL_HASH ALGO=value] # Hash of file at URL [URL_MD5 md5] # Equivalent to URL_HASH MD5=md5 [TLS_VERIFY bool] # Should certificate for https be checked [TLS_CAINFO file] # Path to a certificate authority file [TIMEOUT seconds] # Time allowed for file download operations #--Update/Patch step---------- [UPDATE_COMMAND cmd...] # Source work-tree update command [PATCH_COMMAND cmd...] # Command to patch downloaded source #--Configure step------------- [SOURCE_DIR dir] # Source dir to be used for build [CONFIGURE_COMMAND cmd...] # Build tree configuration command [CMAKE_COMMAND /.../cmake] # Specify alternative cmake executable [CMAKE_GENERATOR gen] # Specify generator for native build [CMAKE_GENERATOR_TOOLSET t] # Generator-specific toolset name [CMAKE_ARGS args...] # Arguments to CMake command line [CMAKE_CACHE_ARGS args...] # Initial cache arguments, of the form -Dvar:string=on #--Build step----------------- [BINARY_DIR dir] # Specify build dir location [BUILD_COMMAND cmd...] # Command to drive the native build [BUILD_IN_SOURCE 1] # Use source dir for build dir #--Install step--------------- [INSTALL_DIR dir] # Installation prefix [INSTALL_COMMAND cmd...] # Command to drive install after build #--Test step------------------ [TEST_BEFORE_INSTALL 1] # Add test step executed before install step [TEST_AFTER_INSTALL 1] # Add test step executed after install step [TEST_COMMAND cmd...] # Command to drive test #--Output logging------------- [LOG_DOWNLOAD 1] # Wrap download in script to log output [LOG_UPDATE 1] # Wrap update in script to log output [LOG_CONFIGURE 1] # Wrap configure in script to log output [LOG_BUILD 1] # Wrap build in script to log output [LOG_TEST 1] # Wrap test in script to log output [LOG_INSTALL 1] # Wrap install in script to log output #--Custom targets------------- [STEP_TARGETS st1 st2 ...] # Generate custom targets for these steps )

The *_DIR options specify directories for the project, with default directories computed as follows. If the PREFIX option is given to ExternalProject_Add() or the EP_PREFIX directory prop- erty is set, then an external project is built and installed under the specified prefix:

TMP_DIR = <prefix>/tmp STAMP_DIR = <prefix>/src/<name>-stamp DOWNLOAD_DIR = <prefix>/src SOURCE_DIR = <prefix>/src/<name> BINARY_DIR = <prefix>/src/<name>-build INSTALL_DIR = <prefix>

Otherwise, if the EP_BASE directory property is set then compo- nents of an external project are stored under the specified base:

TMP_DIR = <base>/tmp/<name> STAMP_DIR = <base>/Stamp/<name> DOWNLOAD_DIR = <base>/Download/<name> SOURCE_DIR = <base>/Source/<name> BINARY_DIR = <base>/Build/<name> INSTALL_DIR = <base>/Install/<name>

If no PREFIX, EP_PREFIX, or EP_BASE is specified then the default is to set PREFIX to "<name>-prefix". Relative paths are interpreted with respect to the build directory corresponding to the source directory in which ExternalProject_Add is invoked.

If SOURCE_DIR is explicitly set to an existing directory the project will be built from it. Otherwise a download step must be specified using one of the DOWNLOAD_COMMAND, CVS_*, SVN_*, or URL options. The URL option may refer locally to a directory or source tarball, or refer to a remote tarball (e.g. http://.../src.tgz).

The ExternalProject_Add_Step function adds a custom step to an external project:

ExternalProject_Add_Step(<name> <step> # Names of project and custom step [COMMAND cmd...] # Command line invoked by this step [COMMENT "text..."] # Text printed when step executes [DEPENDEES steps...] # Steps on which this step depends [DEPENDERS steps...] # Steps that depend on this step [DEPENDS files...] # Files on which this step depends [ALWAYS 1] # No stamp file, step always runs [WORKING_DIRECTORY dir] # Working directory for command [LOG 1] # Wrap step in script to log output )

The command line, comment, and working directory of every stan- dard and custom step is processed to replace tokens <SOURCE_DIR>, <BINARY_DIR>, <INSTALL_DIR>, and <TMP_DIR> with corresponding property values.

Any builtin step that specifies a "<step>_COMMAND cmd..." or custom step that specifies a "COMMAND cmd..." may specify addi- tional command lines using the form "COMMAND cmd...". At build time the commands will be executed in order and aborted if any one fails. For example:

... BUILD_COMMAND make COMMAND echo done ...

specifies to run "make" and then "echo done" during the build step. Whether the current working directory is preserved between commands is not defined. Behavior of shell operators like "&&" is not defined.

The ExternalProject_Get_Property function retrieves external project target properties:

ExternalProject_Get_Property(<name> [prop1 [prop2 [...]]])

It stores property values in variables of the same name. Prop- erty names correspond to the keyword argument names of Exter- nalProject_Add.

The ExternalProject_Add_StepTargets function generates custom targets for the steps listed:

ExternalProject_Add_StepTargets(<name> [step1 [step2 [...]]])

If STEP_TARGETS is set then ExternalProject_Add_StepTargets is automatically called at the end of matching calls to External- Project_Add_Step. Pass STEP_TARGETS explicitly to individual ExternalProject_Add calls, or implicitly to all ExternalPro- ject_Add calls by setting the directory property EP_STEP_TAR- GETS.

If STEP_TARGETS is not set, clients may still manually call ExternalProject_Add_StepTargets after calling ExternalPro- ject_Add or ExternalProject_Add_Step.

This functionality is provided to make it easy to drive the steps independently of each other by specifying targets on build command lines. For example, you may be submitting to a sub-project based dashboard, where you want to drive the configure portion of the build, then submit to the dashboard, followed by the build portion, followed by tests. If you invoke a custom target that depends on a step halfway through the step dependency chain, then all the previous steps will also run to ensure everything is up to date.

For example, to drive configure, build and test steps indepen- dently for each ExternalProject_Add call in your project, write the following line prior to any ExternalProject_Add calls in your CMakeLists file:

set_property(DIRECTORY PROPERTY EP_STEP_TARGETS configure build test)

FeatureSummary Macros for generating a summary of enabled/disabled features

This module provides the macros feature_summary(), set_pack- age_properties() and add_feature_info(). For compatibility it also still provides set_package_info(), set_feature_info(), print_enabled_features() and print_disabled_features().

These macros can be used to generate a summary of enabled and disabled packages and/or feature for a build tree:

-- The following OPTIONAL packages have been found: LibXml2 (required version >= 2.4) , XML processing library. , <http://xmlsoft.org> * Enables HTML-import in MyWordProcessor * Enables odt-export in MyWordProcessor PNG , A PNG image library. , <http://www.libpng.org/pub/png/> * Enables saving screenshots -- The following OPTIONAL packages have not been found: Lua51 , The Lua scripting language. , <http://www.lua.org> * Enables macros in MyWordProcessor Foo , Foo provides cool stuff.

FEATURE_SUMMARY( [FILENAME <file>] [APPEND] [VAR <variable_name>] [INCLUDE_QUIET_PACKAGES] [FATAL_ON_MISSING_REQUIRED_PACKAGES] [DESCRIPTION "Found packages:"] WHAT (ALL | PACKAGES_FOUND | PACKAGES_NOT_FOUND | ENABLED_FEATURES | DISABLED_FEATURES] )

The FEATURE_SUMMARY() macro can be used to print information about enabled or disabled packages or features of a project. By default, only the names of the features/packages will be printed and their required version when one was specified. Use SET_PACK- AGE_PROPERTIES() to add more useful information, like e.g. a download URL for the respective package or their purpose in the project.

The WHAT option is the only mandatory option. Here you specify what information will be printed:

ALL: print everything ENABLED_FEATURES: the list of all features which are enabled DISABLED_FEATURES: the list of all features which are disabled PACKAGES_FOUND: the list of all packages which have been found PACKAGES_NOT_FOUND: the list of all packages which have not been found OPTIONAL_PACKAGES_FOUND: only those packages which have been found which have the type OPTIONAL OPTIONAL_PACKAGES_NOT_FOUND: only those packages which have not been found which have the type OPTIONAL RECOMMENDED_PACKAGES_FOUND: only those packages which have been found which have the type RECOMMENDED RECOMMENDED_PACKAGES_NOT_FOUND: only those packages which have not been found which have the type RECOMMENDED REQUIRED_PACKAGES_FOUND: only those packages which have been found which have the type REQUIRED REQUIRED_PACKAGES_NOT_FOUND: only those packages which have not been found which have the type REQUIRED RUNTIME_PACKAGES_FOUND: only those packages which have been found which have the type RUNTIME RUNTIME_PACKAGES_NOT_FOUND: only those packages which have not been found which have the type RUNTIME

If a FILENAME is given, the information is printed into this file. If APPEND is used, it is appended to this file, otherwise the file is overwritten if it already existed. If the VAR option is used, the information is "printed" into the specified vari- able. If FILENAME is not used, the information is printed to the terminal. Using the DESCRIPTION option a description or headline can be set which will be printed above the actual content. If INCLUDE_QUIET_PACKAGES is given, packages which have been searched with find_package(... QUIET) will also be listed. By default they are skipped. If FATAL_ON_MISSING_REQUIRED_PACKAGES is given, CMake will abort if a package which is marked as REQUIRED has not been found.

Example 1, append everything to a file:

feature_summary(WHAT ALL FILENAME ${CMAKE_BINARY_DIR}/all.log APPEND)

Example 2, print the enabled features into the variable enabled- FeaturesText, including QUIET packages:

feature_summary(WHAT ENABLED_FEATURES INCLUDE_QUIET_PACKAGES DESCRIPTION "Enabled Features:" VAR enabledFeaturesText) message(STATUS "${enabledFeaturesText}")

SET_PACKAGE_PROPERTIES(<name> PROPERTIES [ URL <url> ] [ DESCRIPTION <description> ] [ TYPE (RUNTIME|OPTIONAL|RECOMMENDED|REQUIRED) ] [ PURPOSE <purpose> ] )

Use this macro to set up information about the named package, which can then be displayed via FEATURE_SUMMARY(). This can be done either directly in the Find-module or in the project which uses the module after the find_package() call. The features for which information can be set are added automatically by the find_package() command.

URL: this should be the homepage of the package, or something similar. Ideally this is set already directly in the Find-mod- ule.

DESCRIPTION: A short description what that package is, at most one sentence. Ideally this is set already directly in the Find-module.

TYPE: What type of dependency has the using project on that package. Default is OPTIONAL. In this case it is a package which can be used by the project when available at buildtime, but it also work without. RECOMMENDED is similar to OPTIONAL, i.e. the project will build if the package is not present, but the func- tionality of the resulting binaries will be severly limited. If a REQUIRED package is not available at buildtime, the project may not even build. This can be combined with the FATAL_ON_MISS- ING_REQUIRED_PACKAGES argument for feature_summary(). Last, a RUNTIME package is a package which is actually not used at all during the build, but which is required for actually running the resulting binaries. So if such a package is missing, the project can still be built, but it may not work later on. If set_pack- age_properties() is called multiple times for the same package with different TYPEs, the TYPE is only changed to higher TYPEs ( RUNTIME < OPTIONAL < RECOMMENDED < REQUIRED ), lower TYPEs are ignored. The TYPE property is project-specific, so it cannot be set by the Find-module, but must be set in the project.

PURPOSE: This describes which features this package enables in the project, i.e. it tells the user what functionality he gets in the resulting binaries. If set_package_properties() is called multiple times for a package, all PURPOSE properties are appended to a list of purposes of the package in the project. As the TYPE property, also the PURPOSE property is project-spe- cific, so it cannot be set by the Find-module, but must be set in the project.

Example for setting the info for a package:

find_package(LibXml2) set_package_properties(LibXml2 PROPERTIES DESCRIPTION "A XML processing library." URL "http://xmlsoft.org/")

set_package_properties(LibXml2 PROPERTIES TYPE RECOMMENDED PURPOSE "Enables HTML-import in MyWordProcessor") ... set_package_properties(LibXml2 PROPERTIES TYPE OPTIONAL PURPOSE "Enables odt-export in MyWordProcessor")

find_package(DBUS) set_package_properties(DBUS PROPERTIES TYPE RUNTIME PURPOSE "Necessary to disable the screensaver during a presentation" )

ADD_FEATURE_INFO(<name> <enabled> <description>)

Use this macro to add information about a feature with the given <name>. <enabled> contains whether this feature is enabled or not, <description> is a text describing the feature. The infor- mation can be displayed using feature_summary() for ENABLED_FEA- TURES and DISABLED_FEATURES respectively.

Example for setting the info for a feature:

option(WITH_FOO "Help for foo" ON) add_feature_info(Foo WITH_FOO "The Foo feature provides very cool stuff.")

The following macros are provided for compatibility with previ- ous CMake versions:

SET_PACKAGE_INFO(<name> <description> [<url> [<purpose>] ] )

Use this macro to set up information about the named package, which can then be displayed via FEATURE_SUMMARY(). This can be done either directly in the Find-module or in the project which uses the module after the find_package() call. The features for which information can be set are added automatically by the find_package() command.

PRINT_ENABLED_FEATURES()

Does the same as FEATURE_SUMMARY(WHAT ENABLED_FEATURES DESCRIP- TION "Enabled features:")

PRINT_DISABLED_FEATURES()

Does the same as FEATURE_SUMMARY(WHAT DISABLED_FEATURES DESCRIPTION "Disabled features:")

SET_FEATURE_INFO(<name> <description> [<url>] )

Does the same as SET_PACKAGE_INFO(<name> <description> <url> )

FindALSA Find alsa

FindAVIFile Locate AVIFILE library and include paths

AVIFILE (http://avifile.sourceforge.net/)is a set of libraries for i386 machines to use various AVI codecs. Support is limited beyond Linux. Windows provides native AVI support, and so doesnt need this library. This module defines

AVIFILE_INCLUDE_DIR, where to find avifile.h , etc. AVIFILE_LIBRARIES, the libraries to link against AVIFILE_DEFINITIONS, definitions to use when compiling AVIFILE_FOUND, If false, dont try to use AVIFILE

FindArmadillo Find Armadillo

Find the Armadillo C++ library

Using Armadillo:

find_package(Armadillo REQUIRED) include_directories(${ARMADILLO_INCLUDE_DIRS}) add_executable(foo foo.cc) target_link_libraries(foo ${ARMADILLO_LIBRARIES})

This module sets the following variables:

ARMADILLO_FOUND - set to true if the library is found ARMADILLO_INCLUDE_DIRS - list of required include directories ARMADILLO_LIBRARIES - list of libraries to be linked ARMADILLO_VERSION_MAJOR - major version number ARMADILLO_VERSION_MINOR - minor version number ARMADILLO_VERSION_PATCH - patch version number ARMADILLO_VERSION_STRING - version number as a string (ex: "1.0.4") ARMADILLO_VERSION_NAME - name of the version (ex: "Antipodean Antileech")

FindBISON Find bison executable and provides macros to generate custom build rules

The module defines the following variables:

BISON_EXECUTABLE - path to the bison program BISON_VERSION - version of bison BISON_FOUND - true if the program was found

The minimum required version of bison can be specified using the standard CMake syntax, e.g. find_package(BISON 2.1.3)

If bison is found, the module defines the macros:

BISON_TARGET(<Name> <YaccInput> <CodeOutput> [VERBOSE <file>] [COMPILE_FLAGS <string>])

which will create a custom rule to generate a parser. <YaccIn- put> is the path to a yacc file. <CodeOutput> is the name of the source file generated by bison. A header file is also be generated, and contains the token list. If COMPILE_FLAGS option is specified, the next parameter is added in the bison command line. if VERBOSE option is specified, <file> is created and contains verbose descriptions of the grammar and parser. The macro defines a set of variables:

BISON_${Name}_DEFINED - true is the macro ran successfully BISON_${Name}_INPUT - The input source file, an alias for <YaccInput> BISON_${Name}_OUTPUT_SOURCE - The source file generated by bison BISON_${Name}_OUTPUT_HEADER - The header file generated by bison BISON_${Name}_OUTPUTS - The sources files generated by bison BISON_${Name}_COMPILE_FLAGS - Options used in the bison command line

==================================================================== Example:

find_package(BISON) BISON_TARGET(MyParser parser.y ${CMAKE_CURRENT_BINARY_DIR}/parser.cpp) add_executable(Foo main.cpp ${BISON_MyParser_OUTPUTS}) ====================================================================

FindBLAS Find BLAS library

This module finds an installed fortran library that implements the BLAS linear-algebra interface (see http://www.netlib.org/blas/). The list of libraries searched for is taken from the autoconf macro file, acx_blas.m4 (distributed at http://ac-archive.sourceforge.net/ac-archive/acx_blas.html).

This module sets the following variables:

BLAS_FOUND - set to true if a library implementing the BLAS interface is found BLAS_LINKER_FLAGS - uncached list of required linker flags (excluding -l and -L). BLAS_LIBRARIES - uncached list of libraries (using full path name) to link against to use BLAS BLAS95_LIBRARIES - uncached list of libraries (using full path name) to link against to use BLAS95 interface BLAS95_FOUND - set to true if a library implementing the BLAS f95 interface is found BLA_STATIC if set on this determines what kind of linkage we do (static) BLA_VENDOR if set checks only the specified vendor, if not set checks all the possibilities BLA_F95 if set on tries to find the f95 interfaces for BLAS/LAPACK

C/CXX should be enabled to use Intel mkl

FindBZip2 Try to find BZip2

Once done this will define

BZIP2_FOUND - system has BZip2 BZIP2_INCLUDE_DIR - the BZip2 include directory BZIP2_LIBRARIES - Link these to use BZip2 BZIP2_NEED_PREFIX - this is set if the functions are prefixed with BZ2_ BZIP2_VERSION_STRING - the version of BZip2 found (since CMake 2.8.8)

FindBoost Find Boost include dirs and libraries

Use this module by invoking find_package with the form:

find_package(Boost [version] [EXACT] # Minimum or EXACT version e.g. 1.36.0 [REQUIRED] # Fail with error if Boost is not found [COMPONENTS <libs>...] # Boost libraries by their canonical name ) # e.g. "date_time" for "libboost_date_time"

This module finds headers and requested component libraries OR a CMake package configuration file provided by a "Boost CMake" build. For the latter case skip to the "Boost CMake" section below. For the former case results are reported in variables:

Boost_FOUND - True if headers and requested libraries were found Boost_INCLUDE_DIRS - Boost include directories Boost_LIBRARY_DIRS - Link directories for Boost libraries Boost_LIBRARIES - Boost component libraries to be linked Boost_<C>_FOUND - True if component <C> was found (<C> is upper-case) Boost_<C>_LIBRARY - Libraries to link for component <C> (may include target_link_libraries debug/optimized keywords) Boost_VERSION - BOOST_VERSION value from boost/version.hpp Boost_LIB_VERSION - Version string appended to library filenames Boost_MAJOR_VERSION - Boost major version number (X in X.y.z) Boost_MINOR_VERSION - Boost minor version number (Y in x.Y.z) Boost_SUBMINOR_VERSION - Boost subminor version number (Z in x.y.Z) Boost_LIB_DIAGNOSTIC_DEFINITIONS (Windows) - Pass to add_definitions() to have diagnostic information about Boosts automatic linking displayed during compilation

This module reads hints about search locations from variables:

BOOST_ROOT - Preferred installation prefix (or BOOSTROOT) BOOST_INCLUDEDIR - Preferred include directory e.g. <prefix>/include BOOST_LIBRARYDIR - Preferred library directory e.g. <prefix>/lib Boost_NO_SYSTEM_PATHS - Set to ON to disable searching in locations not specified by these hint variables. Default is OFF. Boost_ADDITIONAL_VERSIONS - List of Boost versions not known to this module (Boost install locations may contain the version)

and saves search results persistently in CMake cache entries:

Boost_INCLUDE_DIR - Directory containing Boost headers Boost_LIBRARY_DIR - Directory containing Boost libraries Boost_<C>_LIBRARY_DEBUG - Component <C> library debug variant Boost_<C>_LIBRARY_RELEASE - Component <C> library release variant

Users may set these hints or results as cache entries. Projects should not read these entries directly but instead use the above result variables. Note that some hint names start in upper-case "BOOST". One may specify these as environment variables if they are not specified as CMake variables or cache entries.

This module first searches for the Boost header files using the above hint variables (excluding BOOST_LIBRARYDIR) and saves the result in Boost_INCLUDE_DIR. Then it searches for requested component libraries using the above hints (excluding BOOST_INCLUDEDIR and Boost_ADDITIONAL_VERSIONS), "lib" directo- ries near Boost_INCLUDE_DIR, and the library name configuration settings below. It saves the library directory in Boost_LIBRARY_DIR and individual library locations in Boost_<C>_LIBRARY_DEBUG and Boost_<C>_LIBRARY_RELEASE. When one changes settings used by previous searches in the same build tree (excluding environment variables) this module discards pre- vious search results affected by the changes and searches again.

Boost libraries come in many variants encoded in their file name. Users or projects may tell this module which variant to find by setting variables:

Boost_USE_MULTITHREADED - Set to OFF to use the non-multithreaded libraries ( mt tag). Default is ON. Boost_USE_STATIC_LIBS - Set to ON to force the use of the static libraries. Default is OFF. Boost_USE_STATIC_RUNTIME - Set to ON or OFF to specify whether to use libraries linked statically to the C++ runtime (s tag). Default is platform dependent. Boost_USE_DEBUG_PYTHON - Set to ON to use libraries compiled with a debug Python build ( y tag). Default is OFF. Boost_USE_STLPORT - Set to ON to use libraries compiled with STLPort ( p tag). Default is OFF. Boost_USE_STLPORT_DEPRECATED_NATIVE_IOSTREAMS - Set to ON to use libraries compiled with STLPort deprecated "native iostreams" ( n tag). Default is OFF. Boost_COMPILER - Set to the compiler-specific library suffix (e.g. "-gcc43"). Default is auto-computed for the C++ compiler in use. Boost_THREADAPI - Suffix for "thread" component library name, such as "pthread" or "win32". Names with and without this suffix will both be tried.

Other variables one may set to control this module are:

Boost_DEBUG - Set to ON to enable debug output from FindBoost. Please enable this before filing any bug report. Boost_DETAILED_FAILURE_MSG - Set to ON to add detailed information to the failure message even when the REQUIRED option is not given to the find_package call. Boost_REALPATH - Set to ON to resolve symlinks for discovered libraries to assist with packaging. For example, the "system" component library may be resolved to "/usr/lib/libboost_system.so.1.42.0" instead of "/usr/lib/libboost_system.so". This does not affect linking and should not be enabled unless the user needs this information.

On Visual Studio and Borland compilers Boost headers request automatic linking to corresponding libraries. This requires matching libraries to be linked explicitly or available in the link library search path. In this case setting Boost_USE_STATIC_LIBS to OFF may not achieve dynamic linking. Boost automatic linking typically requests static libraries with a few exceptions (such as Boost.Python). Use

add_definitions(${Boost_LIB_DIAGNOSTIC_DEFINITIONS})

to ask Boost to report information about automatic linking requests.

Example to find Boost headers only:

find_package(Boost 1.36.0) if(Boost_FOUND) include_directories(${Boost_INCLUDE_DIRS}) add_executable(foo foo.cc) endif()

Example to find Boost headers and some libraries:

set(Boost_USE_STATIC_LIBS ON) set(Boost_USE_MULTITHREADED ON) set(Boost_USE_STATIC_RUNTIME OFF) find_package(Boost 1.36.0 COMPONENTS date_time filesystem system ...) if(Boost_FOUND) include_directories(${Boost_INCLUDE_DIRS}) add_executable(foo foo.cc) target_link_libraries(foo ${Boost_LIBRARIES}) endif()

Boost CMake ----------------------------------------------------------

If Boost was built using the boost-cmake project it provides a package configuration file for use with find_packages Config mode. This module looks for the package configuration file called BoostConfig.cmake or boost-config.cmake and stores the result in cache entry "Boost_DIR". If found, the package con- figuration file is loaded and this module returns with no fur- ther action. See documentation of the Boost CMake package con- figuration for details on what it provides.

Set Boost_NO_BOOST_CMAKE to ON to disable the search for boost-cmake.

FindBullet Try to find the Bullet physics engine

This module defines the following variables

BULLET_FOUND - Was bullet found BULLET_INCLUDE_DIRS - the Bullet include directories BULLET_LIBRARIES - Link to this, by default it includes all bullet components (Dynamics, Collision, LinearMath, & SoftBody)

This module accepts the following variables

BULLET_ROOT - Can be set to bullet install path or Windows build path

FindCABLE Find CABLE

This module finds if CABLE is installed and determines where the include files and libraries are. This code sets the following variables:

CABLE the path to the cable executable CABLE_TCL_LIBRARY the path to the Tcl wrapper library CABLE_INCLUDE_DIR the path to the include directory

To build Tcl wrappers, you should add shared library and link it to ${CABLE_TCL_LIBRARY}. You should also add ${CABLE_INCLUDE_DIR} as an include directory.

FindCUDA Tools for building CUDA C files: libraries and build dependen- cies.

This script locates the NVIDIA CUDA C tools. It should work on linux, windows, and mac and should be reasonably up to date with CUDA C releases.

This script makes use of the standard find_package arguments of <VERSION>, REQUIRED and QUIET. CUDA_FOUND will report if an acceptable version of CUDA was found.

The script will prompt the user to specify CUDA_TOOLKIT_ROOT_DIR if the prefix cannot be determined by the location of nvcc in the system path and REQUIRED is specified to find_package(). To use a different installed version of the toolkit set the envi- ronment variable CUDA_BIN_PATH before running cmake (e.g. CUDA_BIN_PATH=/usr/local/cuda1.0 instead of the default /usr/local/cuda) or set CUDA_TOOLKIT_ROOT_DIR after configuring. If you change the value of CUDA_TOOLKIT_ROOT_DIR, various compo- nents that depend on the path will be relocated.

It might be necessary to set CUDA_TOOLKIT_ROOT_DIR manually on certain platforms, or to use a cuda runtime not installed in the default location. In newer versions of the toolkit the cuda library is included with the graphics driver- be sure that the driver version matches what is needed by the cuda runtime ver- sion.

The following variables affect the behavior of the macros in the script (in alphebetical order). Note that any of these flags can be changed multiple times in the same directory before call- ing CUDA_ADD_EXECUTABLE, CUDA_ADD_LIBRARY, CUDA_COMPILE, CUDA_COMPILE_PTX or CUDA_WRAP_SRCS.

CUDA_64_BIT_DEVICE_CODE (Default matches host bit size) -- Set to ON to compile for 64 bit device code, OFF for 32 bit device code. Note that making this different from the host code when generating object or C files from CUDA code just wont work, because size_t gets defined by nvcc in the generated source. If you compile to PTX and then load the file yourself, you can mix bit sizes between device and host.

CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE (Default ON) -- Set to ON if you want the custom build rule to be attached to the source file in Visual Studio. Turn OFF if you add the same cuda file to multiple targets.

This allows the user to build the target from the CUDA file; however, bad things can happen if the CUDA source file is added to multiple targets. When performing parallel builds it is possible for the custom build command to be run more than once and in parallel causing cryptic build errors. VS runs the rules for every source file in the target, and a source can have only one rule no matter how many projects it is added to. When the rule is run from multiple targets race conditions can occur on the generated file. Eventually everything will get built, but if the user is unaware of this behavior, there may be confusion. It would be nice if this script could detect the reuse of source files across multiple targets and turn the option off for the user, but no good solution could be found.

CUDA_BUILD_CUBIN (Default OFF) -- Set to ON to enable and extra compilation pass with the -cubin option in Device mode. The output is parsed and register, shared memory usage is printed during build.

CUDA_BUILD_EMULATION (Default OFF for device mode) -- Set to ON for Emulation mode. -D_DEVICEEMU is defined for CUDA C files when CUDA_BUILD_EMULATION is TRUE.

CUDA_GENERATED_OUTPUT_DIR (Default CMAKE_CURRENT_BINARY_DIR) -- Set to the path you wish to have the generated files placed. If it is blank output files will be placed in CMAKE_CURRENT_BINARY_DIR. Intermediate files will always be placed in CMAKE_CURRENT_BINARY_DIR/CMakeFiles.

CUDA_HOST_COMPILATION_CPP (Default ON) -- Set to OFF for C compilation of host code.

CUDA_HOST_COMPILER (Default CMAKE_C_COMPILER, $(VCInstallDir)/bin for VS) -- Set the host compiler to be used by nvcc. Ignored if -ccbin or --compiler-bindir is already present in the CUDA_NVCC_FLAGS or CUDA_NVCC_FLAGS_<CONFIG> variables. For Visual Studio targets $(VCInstallDir)/bin is a special value that expands out to the path when the command is run from withing VS.

CUDA_NVCC_FLAGS CUDA_NVCC_FLAGS_<CONFIG> -- Additional NVCC command line arguments. NOTE: multiple arguments must be semi-colon delimited (e.g. --compiler-options;-Wall)

CUDA_PROPAGATE_HOST_FLAGS (Default ON) -- Set to ON to propagate CMAKE_{C,CXX}_FLAGS and their configuration dependent counterparts (e.g. CMAKE_C_FLAGS_DEBUG) automatically to the host compiler through nvccs -Xcompiler flag. This helps make the generated host code match the rest of the system better. Sometimes certain flags give nvcc problems, and this will help you turn the flag propagation off. This does not affect the flags supplied directly to nvcc via CUDA_NVCC_FLAGS or through the OPTION flags specified through CUDA_ADD_LIBRARY, CUDA_ADD_EXECUTABLE, or CUDA_WRAP_SRCS. Flags used for shared library compilation are not affected by this flag.

CUDA_SEPARABLE_COMPILATION (Default OFF) -- If set this will enable separable compilation for all CUDA runtime object files. If used outside of CUDA_ADD_EXECUTABLE and CUDA_ADD_LIBRARY (e.g. calling CUDA_WRAP_SRCS directly), CUDA_COMPUTE_SEPARABLE_COMPILATION_OBJECT_FILE_NAME and CUDA_LINK_SEPARABLE_COMPILATION_OBJECTS should be called.

CUDA_VERBOSE_BUILD (Default OFF) -- Set to ON to see all the commands used when building the CUDA file. When using a Makefile generator the value defaults to VERBOSE (run make VERBOSE=1 to see output), although setting CUDA_VERBOSE_BUILD to ON will always print the output.

The script creates the following macros (in alphebetical order):

CUDA_ADD_CUFFT_TO_TARGET( cuda_target ) -- Adds the cufft library to the target (can be any target). Handles whether you are in emulation mode or not.

CUDA_ADD_CUBLAS_TO_TARGET( cuda_target ) -- Adds the cublas library to the target (can be any target). Handles whether you are in emulation mode or not.

CUDA_ADD_EXECUTABLE( cuda_target file0 file1 ... [WIN32] [MACOSX_BUNDLE] [EXCLUDE_FROM_ALL] [OPTIONS ...] ) -- Creates an executable "cuda_target" which is made up of the files specified. All of the non CUDA C files are compiled using the standard build rules specified by CMAKE and the cuda files are compiled to object files using nvcc and the host compiler. In addition CUDA_INCLUDE_DIRS is added automatically to include_directories(). Some standard CMake target calls can be used on the target after calling this macro (e.g. set_target_properties and target_link_libraries), but setting properties that adjust compilation flags will not affect code compiled by nvcc. Such flags should be modified before calling CUDA_ADD_EXECUTABLE, CUDA_ADD_LIBRARY or CUDA_WRAP_SRCS.

CUDA_ADD_LIBRARY( cuda_target file0 file1 ... [STATIC | SHARED | MODULE] [EXCLUDE_FROM_ALL] [OPTIONS ...] ) -- Same as CUDA_ADD_EXECUTABLE except that a library is created.

CUDA_BUILD_CLEAN_TARGET() -- Creates a convience target that deletes all the dependency files generated. You should make clean after running this target to ensure the dependency files get regenerated.

CUDA_COMPILE( generated_files file0 file1 ... [STATIC | SHARED | MODULE] [OPTIONS ...] ) -- Returns a list of generated files from the input source files to be used with ADD_LIBRARY or ADD_EXECUTABLE.

CUDA_COMPILE_PTX( generated_files file0 file1 ... [OPTIONS ...] ) -- Returns a list of PTX files generated from the input source files.

CUDA_COMPUTE_SEPARABLE_COMPILATION_OBJECT_FILE_NAME( output_file_var cuda_target object_files ) -- Compute the name of the intermediate link file used for separable compilation. This file name is typically passed into CUDA_LINK_SEPARABLE_COMPILATION_OBJECTS. output_file_var is produced based on cuda_target the list of objects files that need separable compilation as specified by object_files. If the object_files list is empty, then output_file_var will be empty. This function is called automatically for CUDA_ADD_LIBRARY and CUDA_ADD_EXECUTABLE. Note that this is a function and not a macro.

CUDA_INCLUDE_DIRECTORIES( path0 path1 ... ) -- Sets the directories that should be passed to nvcc (e.g. nvcc -Ipath0 -Ipath1 ... ). These paths usually contain other .cu files.

CUDA_LINK_SEPARABLE_COMPILATION_OBJECTS( output_file_var cuda_target nvcc_flags object_files)

-- Generates the link object required by separable compilation from the given object files. This is called automatically for CUDA_ADD_EXECUTABLE and CUDA_ADD_LIBRARY, but can be called manually when using CUDA_WRAP_SRCS directly. When called from CUDA_ADD_LIBRARY or CUDA_ADD_EXECUTABLE the nvcc_flags passed in are the same as the flags passed in via the OPTIONS argument. The only nvcc flag added automatically is the bitness flag as specified by CUDA_64_BIT_DEVICE_CODE. Note that this is a function instead of a macro.

CUDA_WRAP_SRCS ( cuda_target format generated_files file0 file1 ... [STATIC | SHARED | MODULE] [OPTIONS ...] ) -- This is where all the magic happens. CUDA_ADD_EXECUTABLE, CUDA_ADD_LIBRARY, CUDA_COMPILE, and CUDA_COMPILE_PTX all call this function under the hood.

Given the list of files (file0 file1 ... fileN) this macro generates custom commands that generate either PTX or linkable objects (use "PTX" or "OBJ" for the format argument to switch). Files that dont end with .cu or have the HEADER_FILE_ONLY property are ignored.

The arguments passed in after OPTIONS are extra command line options to give to nvcc. You can also specify per configuration options by specifying the name of the configuration followed by the options. General options must preceed configuration specific options. Not all configurations need to be specified, only the ones provided will be used.

OPTIONS -DFLAG=2 "-DFLAG_OTHER=space in flag" DEBUG -g RELEASE --use_fast_math RELWITHDEBINFO --use_fast_math;-g MINSIZEREL --use_fast_math

For certain configurations (namely VS generating object files with CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE set to ON), no generated file will be produced for the given cuda file. This is because when you add the cuda file to Visual Studio it knows that this file produces an object file and will link in the resulting object file automatically.

This script will also generate a separate cmake script that is used at build time to invoke nvcc. This is for several reasons.

1. nvcc can return negative numbers as return values which confuses Visual Studio into thinking that the command succeeded. The script now checks the error codes and produces errors when there was a problem.

2. nvcc has been known to not delete incomplete results when it encounters problems. This confuses build systems into thinking the target was generated when in fact an unusable file exists. The script now deletes the output files if there was an error.

3. By putting all the options that affect the build into a file and then make the build rule dependent on the file, the output files will be regenerated when the options change.

This script also looks at optional arguments STATIC, SHARED, or MODULE to determine when to target the object compilation for a shared library. BUILD_SHARED_LIBS is ignored in CUDA_WRAP_SRCS, but it is respected in CUDA_ADD_LIBRARY. On some systems special flags are added for building objects intended for shared libraries. A preprocessor macro, <target_name>_EXPORTS is defined when a shared library compilation is detected.

Flags passed into add_definitions with -D or /D are passed along to nvcc.

The script defines the following variables:

CUDA_VERSION_MAJOR -- The major version of cuda as reported by nvcc. CUDA_VERSION_MINOR -- The minor version. CUDA_VERSION CUDA_VERSION_STRING -- CUDA_VERSION_MAJOR.CUDA_VERSION_MINOR

CUDA_TOOLKIT_ROOT_DIR -- Path to the CUDA Toolkit (defined if not set). CUDA_SDK_ROOT_DIR -- Path to the CUDA SDK. Use this to find files in the SDK. This script will not directly support finding specific libraries or headers, as that isnt supported by NVIDIA. If you want to change libraries when the path changes see the FindCUDA.cmake script for an example of how to clear these variables. There are also examples of how to use the CUDA_SDK_ROOT_DIR to locate headers or libraries, if you so choose (at your own risk). CUDA_INCLUDE_DIRS -- Include directory for cuda headers. Added automatically for CUDA_ADD_EXECUTABLE and CUDA_ADD_LIBRARY. CUDA_LIBRARIES -- Cuda RT library. CUDA_CUFFT_LIBRARIES -- Device or emulation library for the Cuda FFT implementation (alternative to: CUDA_ADD_CUFFT_TO_TARGET macro) CUDA_CUBLAS_LIBRARIES -- Device or emulation library for the Cuda BLAS implementation (alterative to: CUDA_ADD_CUBLAS_TO_TARGET macro). CUDA_cupti_LIBRARY -- CUDA Profiling Tools Interface library. Only available for CUDA version 4.0+. CUDA_curand_LIBRARY -- CUDA Random Number Generation library. Only available for CUDA version 3.2+. CUDA_cusparse_LIBRARY -- CUDA Sparse Matrix library. Only available for CUDA version 3.2+. CUDA_npp_LIBRARY -- NVIDIA Performance Primitives library. Only available for CUDA version 4.0+.

Find the CxxTest suite and declare a helper macro for creating unit tests and integrating them with CTest. For more details on CxxTest see http://cxxtest.tigris.org

INPUT Variables

CXXTEST_USE_PYTHON [deprecated since 1.3] Only used in the case both Python & Perl are detected on the system to control which CxxTest code generator is used. Valid only for CxxTest version 3.

NOTE: In older versions of this Find Module, this variable controlled if the Python test generator was used instead of the Perl one, regardless of which scripting language the user had installed.

CXXTEST_TESTGEN_ARGS (since CMake 2.8.3) Specify a list of options to pass to the CxxTest code generator. If not defined, --error-printer is passed.

OUTPUT Variables

CXXTEST_FOUND True if the CxxTest framework was found CXXTEST_INCLUDE_DIRS Where to find the CxxTest include directory CXXTEST_PERL_TESTGEN_EXECUTABLE The perl-based test generator CXXTEST_PYTHON_TESTGEN_EXECUTABLE The python-based test generator CXXTEST_TESTGEN_EXECUTABLE (since CMake 2.8.3) The test generator that is actually used (chosen using user preferences and interpreters found in the system) CXXTEST_TESTGEN_INTERPRETER (since CMake 2.8.3) The full path to the Perl or Python executable on the system

CXXTEST_ADD_TEST(unittest_foo foo_test.cc ${CMAKE_CURRENT_SOURCE_DIR}/foo_test.h) target_link_libraries(unittest_foo foo) # as needed endif()

This will (if CxxTest is found): 1. Invoke the testgen executable to autogenerate foo_test.cc in the binary tree from "foo_test.h" in the current source directory. 2. Create an executable and test called unittest_foo.

#============= Example foo_test.h:

#include <cxxtest/TestSuite.h>

class MyTestSuite : public CxxTest::TestSuite { public: void testAddition( void ) { TS_ASSERT( 1 + 1 > 1 ); TS_ASSERT_EQUALS( 1 + 1, 2 ); } };

FindCygwin this module looks for Cygwin

This module looks for the dart testing software and sets DART_ROOT to point to where it found it.

FindDevIL

This module locates the developers image library. http://ope- nil.sourceforge.net/

This module sets:

IL_LIBRARIES - the name of the IL library. These include the full path to the core DevIL library. This one has to be linked into the application. ILU_LIBRARIES - the name of the ILU library. Again, the full path. This library is for filters and effects, not actual loading. It doesnt have to be linked if the functionality it provides is not used. ILUT_LIBRARIES - the name of the ILUT library. Full path. This part of the library interfaces with OpenGL. It is not strictly needed in applications. IL_INCLUDE_DIR - where to find the il.h, ilu.h and ilut.h files. IL_FOUND - this is set to TRUE if all the above variables were set. This will be set to false if ILU or ILUT are not found, even if they are not needed. In most systems, if one library is found all the others are as well. Thats the way the DevIL developers release it.

FindDoxygen This module looks for Doxygen and the path to Graphvizs dot

Doxygen is a documentation generation tool. Please see http://www.doxygen.org

FindEXPAT Find expat

Find the native EXPAT headers and libraries.

EXPAT_INCLUDE_DIRS - where to find expat.h, etc. EXPAT_LIBRARIES - List of libraries when using expat. EXPAT_FOUND - True if expat found.

FindFLEX Find flex executable and provides a macro to generate custom build rules

The module defines the following variables:

FLEX_FOUND - true is flex executable is found FLEX_EXECUTABLE - the path to the flex executable FLEX_VERSION - the version of flex FLEX_LIBRARIES - The flex libraries FLEX_INCLUDE_DIRS - The path to the flex headers

The minimum required version of flex can be specified using the standard syntax, e.g. find_package(FLEX 2.5.13)

If flex is found on the system, the module provides the macro:

FLEX_TARGET(Name FlexInput FlexOutput [COMPILE_FLAGS <string>])

which creates a custom command to generate the <FlexOutput> file from the <FlexInput> file. If COMPILE_FLAGS option is specified, the next parameter is added to the flex command line. Name is an alias used to get details of this custom command. Indeed the macro defines the following variables:

FLEX_${Name}_DEFINED - true is the macro ran successfully FLEX_${Name}_OUTPUTS - the source file generated by the custom rule, an alias for FlexOutput FLEX_${Name}_INPUT - the flex source file, an alias for ${FlexInput}

Flex scanners oftenly use tokens defined by Bison: the code generated by Flex depends of the header generated by Bison. This module also defines a macro:

ADD_FLEX_BISON_DEPENDENCY(FlexTarget BisonTarget)

which adds the required dependency between a scanner and a parser where <FlexTarget> and <BisonTarget> are the first parameters of respectively FLEX_TARGET and BISON_TARGET macros.

==================================================================== Example:

find_package(BISON) find_package(FLEX)

BISON_TARGET(MyParser parser.y ${CMAKE_CURRENT_BINARY_DIR}/parser.cpp) FLEX_TARGET(MyScanner lexer.l ${CMAKE_CURRENT_BINARY_DIR}/lexer.cpp) ADD_FLEX_BISON_DEPENDENCY(MyScanner MyParser)

include_directories(${CMAKE_CURRENT_BINARY_DIR}) add_executable(Foo Foo.cc ${BISON_MyParser_OUTPUTS} ${FLEX_MyScanner_OUTPUTS} ) ====================================================================

FindFLTK Find the native FLTK includes and library

add_test(AllTestsInFoo foo)

If you would like each Google test to show up in CTest as a test you may use the following macro. NOTE: It will slow down your tests by running an executable for each test and test fixture. You will also have to rerun CMake after adding or removing tests or test fixtures.

GTEST_ADD_TESTS(executable extra_args ARGN)

executable = The path to the test executable extra_args = Pass a list of extra arguments to be passed to executable enclosed in quotes (or "" for none) ARGN = A list of source files to search for tests & test fixtures.

FindGettext Find GNU gettext tools

This module looks for the GNU gettext tools. This module defines the following values:

GETTEXT_MSGMERGE_EXECUTABLE: the full path to the msgmerge tool. GETTEXT_MSGFMT_EXECUTABLE: the full path to the msgfmt tool. GETTEXT_FOUND: True if gettext has been found. GETTEXT_VERSION_STRING: the version of gettext found (since CMake 2.8.8)

Additionally it provides the following macros: GETTEXT_CREATE_TRANSLATIONS ( outputFile [ALL] file1 ... fileN )

This will create a target "translations" which will convert the given input po files into the binary output mo file. If the ALL option is used, the translations will also be created when building the default target.

GETTEXT_PROCESS_POT( <potfile> [ALL] [INSTALL_DESTINATION <dest- dir>] LANGUAGES <lang1> <lang2> ... )

Process the given pot file to mo files. If INSTALL_DESTINATION is given then automatically install rules will be created, the language subdirectory will be taken into account (by default use share/locale/). If ALL is specified, the pot file is processed when building the all traget. It creates a custom target "potfile".

GETTEXT_PROCESS_PO_FILES( <lang> [ALL] [INSTALL_DESTINATION <dir>] PO_FILES <po1> <po2> ... )

Process the given po files to mo files for the given language. If INSTALL_DESTINATION is given then automatically install rules will be created, the language subdirectory will be taken into account (by default use share/locale/). If ALL is specified, the po files are processed when building the all traget. It creates a custom target "pofiles".

FindGit

The module defines the following variables:

GIT_EXECUTABLE - path to git command line client GIT_FOUND - true if the command line client was found GIT_VERSION_STRING - the version of git found (since CMake 2.8.8)

Example usage:

find_package(Git) if(GIT_FOUND) message("git found: ${GIT_EXECUTABLE}") endif()

FindGnuTLS Try to find the GNU Transport Layer Security library (gnutls)

Once done this will define

GNUTLS_FOUND - System has gnutls GNUTLS_INCLUDE_DIR - The gnutls include directory GNUTLS_LIBRARIES - The libraries needed to use gnutls GNUTLS_DEFINITIONS - Compiler switches required for using gnutls

FindGnuplot this module looks for gnuplot

Once done this will define

GNUPLOT_FOUND - system has Gnuplot GNUPLOT_EXECUTABLE - the Gnuplot executable GNUPLOT_VERSION_STRING - the version of Gnuplot found (since CMake 2.8.8)

GNUPLOT_VERSION_STRING will not work for old versions like 3.7.1.

FindHDF5 Find HDF5, a library for reading and writing self describing array data.

This module invokes the HDF5 wrapper compiler that should be installed alongside HDF5. Depending upon the HDF5 Configura- tion, the wrapper compiler is called either h5cc or h5pcc. If this succeeds, the module will then call the compiler with the -show argument to see what flags are used when compiling an HDF5 client application.

The module will optionally accept the COMPONENTS argument. If no COMPONENTS are specified, then the find module will default to finding only the HDF5 C library. If one or more COMPONENTS are specified, the module will attempt to find the language bindings for the specified components. The only valid compo- nents are C, CXX, Fortran, HL, and Fortran_HL. If the COMPO- NENTS argument is not given, the module will attempt to find only the C bindings.

On UNIX systems, this module will read the variable HDF5_USE_STATIC_LIBRARIES to determine whether or not to prefer a static link to a dynamic link for HDF5 and all of its depen- dencies. To use this feature, make sure that the HDF5_USE_STATIC_LIBRARIES variable is set before the call to find_package.

To provide the module with a hint about where to find your HDF5 installation, you can set the environment variable HDF5_ROOT. The Find module will then look in this path when searching for HDF5 executables, paths, and libraries.

In addition to finding the includes and libraries required to compile an HDF5 client application, this module also makes an effort to find tools that come with the HDF5 distribution that may be useful for regression testing.

Call this if you want to have automatic moc file handling. This means if you include "foo.moc" in the source file foo.cpp a moc file for the header foo.h will be created automatically. You can set the property SKIP_AUTOMAKE using set_source_files_properties() to exclude some files in the list from being processed.

KDE3_ADD_MOC_FILES(SRCS_VAR file1 ... fileN )

If you dont use the KDE3_AUTOMOC() macro, for the files listed here moc files will be created (named "foo.moc.cpp")

KDE3_ADD_DCOP_SKELS(SRCS_VAR header1.h ... headerN.h )

Use this to generate DCOP skeletions from the listed headers.

KDE3_ADD_DCOP_STUBS(SRCS_VAR header1.h ... headerN.h )

KDE3_ADD_UI_FILES(SRCS_VAR file1.ui ... fileN.ui )

Use this to add the Qt designer ui files to your application/library.

KDE3_ADD_KCFG_FILES(SRCS_VAR file1.kcfgc ... fileN.kcfgc )

Use this to add KDE kconfig compiler files to your application/library.

KDE3_INSTALL_LIBTOOL_FILE(target)

This will create and install a simple libtool file for the given target.

KDE3_ADD_EXECUTABLE(name file1 ... fileN )

Currently identical to add_executable(), may provide some advanced features in the future.

KDE3_ADD_KPART(name [WITH_PREFIX] file1 ... fileN )

Create a KDE plugin (KPart, kioslave, etc.) from the given source files. If WITH_PREFIX is given, the resulting plugin will have the prefix "lib", otherwise it wont. It creates and installs an appropriate libtool la-file.

KDE3_ADD_KDEINIT_EXECUTABLE(name file1 ... fileN )

Create a KDE application in the form of a module loadable via kdeinit. A library named kdeinit_<name> will be created and a small executable which links to it.

The option KDE3_ENABLE_FINAL to enable all-in-one compilation is no longer supported.

FindMPI Find a Message Passing Interface (MPI) implementation

The Message Passing Interface (MPI) is a library used to write high-performance distributed-memory parallel applications, and is typically deployed on a cluster. MPI is a standard interface (defined by the MPI forum) for which many implementations are available. All of them have somewhat different include paths, libraries to link against, etc., and this module tries to smooth out those differences.

=== Variables ===

This module will set the following variables per language in your project, where <lang> is one of C, CXX, or Fortran:

MPI_<lang>_FOUND TRUE if FindMPI found MPI flags for <lang> MPI_<lang>_COMPILER MPI Compiler wrapper for <lang> MPI_<lang>_COMPILE_FLAGS Compilation flags for MPI programs MPI_<lang>_INCLUDE_PATH Include path(s) for MPI header MPI_<lang>_LINK_FLAGS Linking flags for MPI programs MPI_<lang>_LIBRARIES All libraries to link MPI programs against

Additionally, FindMPI sets the following variables for running MPI programs from the command line:

MPIEXEC Executable for running MPI programs MPIEXEC_NUMPROC_FLAG Flag to pass to MPIEXEC before giving it the number of processors to run on MPIEXEC_PREFLAGS Flags to pass to MPIEXEC directly before the executable to run. MPIEXEC_POSTFLAGS Flags to pass to MPIEXEC after other flags

=== Usage ===

To use this module, simply call FindMPI from a CMakeLists.txt file, or run find_package(MPI), then run CMake. If you are happy with the auto- detected configuration for your language, then youre done. If not, you have two options:

1. Set MPI_<lang>_COMPILER to the MPI wrapper (mpicc, etc.) of your choice and reconfigure. FindMPI will attempt to determine all the necessary variables using THAT compiler s compile and link flags. 2. If this fails, or if your MPI implementation does not come with a compiler wrapper, then set both MPI_<lang>_LIBRARIES and MPI_<lang>_INCLUDE_PATH. You may also set any other variables listed above, but these two are required. This will circumvent autodetection entirely.

When configuration is successful, MPI_<lang>_COMPILER will be set to the compiler wrapper for <lang>, if it was found. MPI_<lang>_FOUND and other variables above will be set if any MPI implementation was found for <lang>, regardless of whether a compiler was found.

When using MPIEXEC to execute MPI applications, you should typi- cally use all of the MPIEXEC flags as follows:

${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} PROCS ${MPIEXEC_PREFLAGS} EXECUTABLE ${MPIEXEC_POSTFLAGS} ARGS

where PROCS is the number of processors on which to execute the program, EXECUTABLE is the MPI program, and ARGS are the argu- ments to pass to the MPI program.

=== Backward Compatibility ===

For backward compatibility with older versions of FindMPI, these variables are set, but deprecated:

MPI_FOUND MPI_COMPILER MPI_LIBRARY MPI_COMPILE_FLAGS MPI_INCLUDE_PATH MPI_EXTRA_LIBRARY MPI_LINK_FLAGS MPI_LIBRARIES

In new projects, please use the MPI_<lang>_XXX equivalents.

FindMatlab this module looks for Matlab

Once done this will define

OPENGL_FOUND - system has OpenGL OPENGL_XMESA_FOUND - system has XMESA OPENGL_GLU_FOUND - system has GLU OPENGL_INCLUDE_DIR - the GL include directory OPENGL_LIBRARIES - Link these to use OpenGL and GLU

If you want to use just GL you can use these values

OPENGL_gl_LIBRARY - Path to OpenGL Library OPENGL_glu_LIBRARY - Path to GLU Library

On OSX default to using the framework version of opengl People will have to change the cache values of OPENGL_glu_LIBRARY and OPENGL_gl_LIBRARY to use OpenGL with X11 on OSX

FindOpenMP Finds OpenMP support

This module can be used to detect OpenMP support in a compiler. If the compiler supports OpenMP, the flags required to compile with OpenMP support are returned in variables for the different languages. The variables may be empty if the compiler does not need a special flag to support OpenMP.

The following variables are set:

OpenMP_C_FLAGS - flags to add to the C compiler for OpenMP support OpenMP_CXX_FLAGS - flags to add to the CXX compiler for OpenMP support OPENMP_FOUND - true if openmp is detected

Supported compilers can be found at http://openmp.org/wp/openmp-compilers/

FindOpenSSL Try to find the OpenSSL encryption library

Once done this will define

OPENSSL_ROOT_DIR - Set this variable to the root installation of OpenSSL

Read-Only variables:

FindOpenSceneGraph Find OpenSceneGraph

This module searches for the OpenSceneGraph core "osg" library as well as OpenThreads, and whatever additional COMPONENTS (nodekits) that you specify.

See http://www.openscenegraph.org

NOTE: To use this module effectively you must either require CMake >= 2.6.3 with cmake_minimum_required(VERSION 2.6.3) or download and place FindOpenThreads.cmake, Findosg_func- tions.cmake, Findosg.cmake, and Find<etc>.cmake files into your CMAKE_MODULE_PATH.

==================================

This module accepts the following variables (note mixed case)

OpenSceneGraph_DEBUG - Enable debugging output

OpenSceneGraph_MARK_AS_ADVANCED - Mark cache variables as advanced automatically

The following environment variables are also respected for find- ing the OSG and it s various components. CMAKE_PREFIX_PATH can also be used for this (see find_library() CMake documentation).

<MODULE>_DIR (where MODULE is of the form "OSGVOLUME" and there is a FindosgVolume.cmake file) OSG_DIR OSGDIR OSG_ROOT

[CMake 2.8.10]: The CMake variable OSG_DIR can now be used as well to influence detection, instead of needing to specify an environment variable.

This module defines the following output variables:

OPENSCENEGRAPH_FOUND - Was the OSG and all of the specified components found?

OPENSCENEGRAPH_VERSION - The version of the OSG which was found

OPENSCENEGRAPH_INCLUDE_DIRS - Where to find the headers

OPENSCENEGRAPH_LIBRARIES - The OSG libraries

================================== Example Usage:

find_package(OpenSceneGraph 2.0.0 REQUIRED osgDB osgUtil) # libOpenThreads & libosg automatically searched include_directories(${OPENSCENEGRAPH_INCLUDE_DIRS})

add_executable(foo foo.cc) target_link_libraries(foo ${OPENSCENEGRAPH_LIBRARIES})

FindOpenThreads

OpenThreads is a C++ based threading library. Its largest user- base seems to OpenSceneGraph so you might notice I accept OSGDIR as an environment path. I consider this part of the Findosg* suite used to find OpenSceneGraph components. Each component is separate and you must opt in to each module.

Locate OpenThreads This module defines OPENTHREADS_LIBRARY OPENTHREADS_FOUND, if false, do not try to link to OpenThreads OPENTHREADS_INCLUDE_DIR, where to find the headers

$OPENTHREADS_DIR is an environment variable that would corre- spond to the ./configure --prefix=$OPENTHREADS_DIR used in building osg.

[CMake 2.8.10]: The CMake variables OPENTHREADS_DIR or OSG_DIR can now be used as well to influence detection, instead of need- ing to specify an environment variable.

Created by Eric Wing.

FindPHP4 Find PHP4

This module finds if PHP4 is installed and determines where the include files and libraries are. It also determines what the name of the library is. This code sets the following variables:

PHP4_INCLUDE_PATH = path to where php.h can be found PHP4_EXECUTABLE = full path to the php4 binary

FindPNG Find the native PNG includes and library

This module searches libpng, the library for working with PNG images.

It defines the following variables

PNG_INCLUDE_DIRS, where to find png.h, etc. PNG_LIBRARIES, the libraries to link against to use PNG. PNG_DEFINITIONS - You should add_definitons(${PNG_DEFINITIONS}) before compiling code that includes png library files. PNG_FOUND, If false, do not try to use PNG. PNG_VERSION_STRING - the version of the PNG library found (since CMake 2.8.8)

Also defined, but not for general use are

PNG_LIBRARY, where to find the PNG library.

For backward compatiblity the variable PNG_INCLUDE_DIR is also set. It has the same value as PNG_INCLUDE_DIRS.

Since PNG depends on the ZLib compression library, none of the above will be defined unless ZLib can be found.

FindPackageHandleStandardArgs

FIND_PACKAGE_HANDLE_STANDARD_ARGS(<name> ... )

This function is intended to be used in FindXXX.cmake modules files. It handles the REQUIRED, QUIET and version-related argu- ments to find_package(). It also sets the <packagename>_FOUND variable. The package is considered found if all variables <var1>... listed contain valid results, e.g. valid filepaths.

There are two modes of this function. The first argument in both modes is the name of the Find-module where it is called (in original casing).

The first simple mode looks like this:

FIND_PACKAGE_HANDLE_STANDARD_ARGS(<name> (DEFAULT_MSG|"Custom failure message") <var1>...<varN> )

If the variables <var1> to <varN> are all valid, then <UPPER- CASED_NAME>_FOUND will be set to TRUE. If DEFAULT_MSG is given as second argument, then the function will generate itself use- ful success and error messages. You can also supply a custom error message for the failure case. This is not recommended.

The second mode is more powerful and also supports version checking:

FIND_PACKAGE_HANDLE_STANDARD_ARGS(NAME [FOUND_VAR <resultVar>] [REQUIRED_VARS <var1>...<varN>] [VERSION_VAR <versionvar>] [HANDLE_COMPONENTS] [CONFIG_MODE] [FAIL_MESSAGE "Custom failure message"] )

In this mode, the name of the result-variable can be set either to either <UPPERCASED_NAME>_FOUND or <OriginalCase_Name>_FOUND using the FOUND_VAR option. Other names for the result-variable are not allowed. So for a Find-module named FindFooBar.cmake, the two possible names are FooBar_FOUND and FOOBAR_FOUND. It is recommended to use the original case version. If the FOUND_VAR option is not used, the default is <UPPERCASED_NAME>_FOUND.

As in the simple mode, if <var1> through <varN> are all valid, <packagename>_FOUND will be set to TRUE. After REQUIRED_VARS the variables which are required for this package are listed. Fol- lowing VERSION_VAR the name of the variable can be specified which holds the version of the package which has been found. If this is done, this version will be checked against the (poten- tially) specified required version used in the find_package() call. The EXACT keyword is also handled. The default messages include information about the required version and the version which has been actually found, both if the version is ok or not. If the package supports components, use the HANDLE_COMPONENTS option to enable handling them. In this case, find_package_han- dle_standard_args() will report which components have been found and which are missing, and the <packagename>_FOUND variable will be set to FALSE if any of the required components (i.e. not the ones listed after OPTIONAL_COMPONENTS) are missing. Use the option CONFIG_MODE if your FindXXX.cmake module is a wrapper for a find_package(... NO_MODULE) call. In this case VERSION_VAR will be set to <NAME>_VERSION and the macro will automatically check whether the Config module was found. Via FAIL_MESSAGE a custom failure message can be specified, if this is not used, the default message will be displayed.

Example for mode 1:

find_package_handle_standard_args(LibXml2 DEFAULT_MSG LIBXML2_LIBRARY LIBXML2_INCLUDE_DIR)

LibXml2 is considered to be found, if both LIBXML2_LIBRARY and LIBXML2_INCLUDE_DIR are valid. Then also LIBXML2_FOUND is set to TRUE. If it is not found and REQUIRED was used, it fails with FATAL_ERROR, independent whether QUIET was used or not. If it is found, success will be reported, including the content of <var1>. On repeated Cmake runs, the same message wont be printed again.

Example for mode 2:

find_package_handle_standard_args(LibXslt FOUND_VAR LibXslt_FOUND REQUIRED_VARS LibXslt_LIBRARIES LibXslt_INCLUDE_DIRS VERSION_VAR LibXslt_VERSION_STRING)

In this case, LibXslt is considered to be found if the vari- able(s) listed after REQUIRED_VAR are all valid, i.e. LibXslt_LIBRARIES and LibXslt_INCLUDE_DIRS in this case. The result will then be stored in LibXslt_FOUND . Also the version of LibXslt will be checked by using the version contained in LibXslt_VERSION_STRING. Since no FAIL_MESSAGE is given, the default messages will be printed.

Another example for mode 2:

find_package(Automoc4 QUIET NO_MODULE HINTS /opt/automoc4) find_package_handle_standard_args(Automoc4 CONFIG_MODE)

In this case, FindAutmoc4.cmake wraps a call to find_pack- age(Automoc4 NO_MODULE) and adds an additional search directory for automoc4. Here the result will be stored in AUTOMOC4_FOUND. The following FIND_PACKAGE_HANDLE_STANDARD_ARGS() call produces a proper success/error message.

FindPackageMessage

FIND_PACKAGE_MESSAGE(<name> "message for user" "find result details")

This macro is intended to be used in FindXXX.cmake modules files. It will print a message once for each unique find result. This is useful for telling the user where a package was found. The first argument specifies the name (XXX) of the package. The second argument specifies the message to display. The third argument lists details about the find result so that if they change the message will be displayed again. The macro also obeys the QUIET argument to the find_package command.

Example:

if(X11_FOUND) FIND_PACKAGE_MESSAGE(X11 "Found X11: ${X11_X11_LIB}" "[${X11_X11_LIB}][${X11_INCLUDE_DIR}]") else() ... endif()

This module finds if PERL is installed and determines where the include files and libraries are. It also determines what the name of the library is. This code sets the following variables:

PERLLIBS_FOUND = True if perl.h & libperl were found PERL_INCLUDE_PATH = path to where perl.h is found PERL_LIBRARY = path to libperl PERL_EXECUTABLE = full path to the perl binary

The minimum required version of Perl can be specified using the standard syntax, e.g. find_package(PerlLibs 6.0)

The following variables are also available if needed (introduced after CMake 2.6.4)

PERL_SITESEARCH = path to the sitesearch install dir PERL_SITELIB = path to the sitelib install directory PERL_VENDORARCH = path to the vendor arch install directory PERL_VENDORLIB = path to the vendor lib install directory PERL_ARCHLIB = path to the arch lib install directory PERL_PRIVLIB = path to the priv lib install directory PERL_EXTRA_C_FLAGS = Compilation flags used to build perl

FindPhysFS

Locate PhysFS library This module defines PHYSFS_LIBRARY, the name of the library to link against PHYSFS_FOUND, if false, do not try to link to PHYSFS PHYSFS_INCLUDE_DIR, where to find physfs.h

$PHYSFSDIR is an environment variable that would correspond to the ./configure --prefix=$PHYSFSDIR used in building PHYSFS.

FindPike Find Pike

This module finds if PIKE is installed and determines where the include files and libraries are. It also determines what the name of the library is. This code sets the following variables:

PIKE_INCLUDE_PATH = path to where program.h is found PIKE_EXECUTABLE = full path to the pike binary

FindPkgConfig a pkg-config module for CMake

Usage:

pkg_check_modules(<PREFIX> [REQUIRED] [QUIET] <MODULE> [<MODULE>]*) checks for all the given modules

pkg_search_module(<PREFIX> [REQUIRED] [QUIET] <MODULE> [<MODULE>]*) checks for given modules and uses the first working one

When the REQUIRED argument was set, macros will fail with an error when module(s) could not be found

When the QUIET argument is set, no status messages will be printed.

It sets the following variables:

PKG_CONFIG_FOUND ... if pkg-config executable was found PKG_CONFIG_EXECUTABLE ... pathname of the pkg-config program PKG_CONFIG_VERSION_STRING ... the version of the pkg-config program found (since CMake 2.8.8)

For the following variables two sets of values exist; first one is the common one and has the given PREFIX. The second set con- tains flags which are given out when pkgconfig was called with the --static option.

<XPREFIX>_FOUND ... set to 1 if module(s) exist <XPREFIX>_LIBRARIES ... only the libraries (w/o the -l) <XPREFIX>_LIBRARY_DIRS ... the paths of the libraries (w/o the -L) <XPREFIX>_LDFLAGS ... all required linker flags <XPREFIX>_LDFLAGS_OTHER ... all other linker flags <XPREFIX>_INCLUDE_DIRS ... the -I preprocessor flags (w/o the -I) <XPREFIX>_CFLAGS ... all required cflags <XPREFIX>_CFLAGS_OTHER ... the other compiler flags

<XPREFIX> = <PREFIX> for common case <XPREFIX> = <PREFIX>_STATIC for static linking

There are some special variables whose prefix depends on the count of given modules. When there is only one module, <PREFIX> stays unchanged. When there are multiple modules, the prefix will be changed to <PREFIX>_<MODNAME>:

<XPREFIX>_VERSION ... version of the module <XPREFIX>_PREFIX ... prefix-directory of the module <XPREFIX>_INCLUDEDIR ... include-dir of the module <XPREFIX>_LIBDIR ... lib-dir of the module

<XPREFIX> = <PREFIX> when |MODULES| == 1, else <XPREFIX> = <PREFIX>_<MODNAME>

A <MODULE> parameter can have the following formats:

{MODNAME} ... matches any version {MODNAME}>={VERSION} ... at least version <VERSION> is required {MODNAME}={VERSION} ... exactly version <VERSION> is required {MODNAME}<={VERSION} ... modules must not be newer than <VERSION>

Examples

pkg_check_modules (GLIB2 glib-2.0)

pkg_check_modules (GLIB2 glib-2.0>=2.10) requires at least version 2.10 of glib2 and defines e.g. GLIB2_VERSION=2.10.3

pkg_check_modules (FOO glib-2.0>=2.10 gtk+-2.0) requires both glib2 and gtk2, and defines e.g. FOO_glib-2.0_VERSION=2.10.3 FOO_gtk+-2.0_VERSION=2.8.20

pkg_check_modules (XRENDER REQUIRED xrender) defines e.g.: XRENDER_LIBRARIES=Xrender;X11 XRENDER_STATIC_LIBRARIES=Xrender;X11;pthread;Xau;Xdmcp

pkg_search_module (BAR libxml-2.0 libxml2 libxml>=2)

FindPostgreSQL Find the PostgreSQL installation.

In Windows, we make the assumption that, if the PostgreSQL files are installed, the default directory will be C:Program FilesPostgreSQL.

This module defines

PostgreSQL_LIBRARIES - the PostgreSQL libraries needed for linking PostgreSQL_INCLUDE_DIRS - the directories of the PostgreSQL headers PostgreSQL_VERSION_STRING - the version of PostgreSQL found (since CMake 2.8.8)

FindProducer

Though Producer isn t directly part of OpenSceneGraph, its pri- mary user is OSG so I consider this part of the Findosg* suite used to find OpenSceneGraph components. Youll notice that I accept OSGDIR as an environment path.

Each component is separate and you must opt in to each module. You must also opt into OpenGL (and OpenThreads?) as these mod- ules wont do it for you. This is to allow you control over your own system piece by piece in case you need to opt out of certain components or change the Find behavior for a particular module (perhaps because the default FindOpenGL.cmake module doesnt work with your system as an example). If you want to use a more convenient module that includes everything, use the FindOpen- SceneGraph.cmake instead of the Findosg*.cmake modules.

Locate Producer This module defines PRODUCER_LIBRARY PRO- DUCER_FOUND, if false, do not try to link to Producer PRO- DUCER_INCLUDE_DIR, where to find the headers

$PRODUCER_DIR is an environment variable that would correspond to the ./configure --prefix=$PRODUCER_DIR used in building osg.

Created by Eric Wing.

FindProtobuf

Locate and configure the Google Protocol Buffers library.

The following variables can be set and are optional:

PROTOBUF_SRC_ROOT_FOLDER - When compiling with MSVC, if this cache variable is set the protobuf-default VS project build locations (vsprojects/Debug & vsprojects/Release) will be searched for libraries and binaries.

PROTOBUF_IMPORT_DIRS - List of additional directories to be searched for imported .proto files. (New in CMake 2.8.8)

Defines the following variables:

PROTOBUF_FOUND - Found the Google Protocol Buffers library (libprotobuf & header files) PROTOBUF_INCLUDE_DIRS - Include directories for Google Protocol Buffers PROTOBUF_LIBRARIES - The protobuf libraries

[New in CMake 2.8.5]

PROTOBUF_PROTOC_LIBRARIES - The protoc libraries PROTOBUF_LITE_LIBRARIES - The protobuf-lite libraries

The following cache variables are also available to set or use:

PROTOBUF_LIBRARY - The protobuf library PROTOBUF_PROTOC_LIBRARY - The protoc library PROTOBUF_INCLUDE_DIR - The include directory for protocol buffers PROTOBUF_PROTOC_EXECUTABLE - The protoc compiler

[New in CMake 2.8.5]

PROTOBUF_LIBRARY_DEBUG - The protobuf library (debug) PROTOBUF_PROTOC_LIBRARY_DEBUG - The protoc library (debug) PROTOBUF_LITE_LIBRARY - The protobuf lite library PROTOBUF_LITE_LIBRARY_DEBUG - The protobuf lite library (debug)

==================================================================== Example:

find_package(Protobuf REQUIRED) include_directories(${PROTOBUF_INCLUDE_DIRS})

include_directories(${CMAKE_CURRENT_BINARY_DIR}) PROTOBUF_GENERATE_CPP(PROTO_SRCS PROTO_HDRS foo.proto) add_executable(bar bar.cc ${PROTO_SRCS} ${PROTO_HDRS}) target_link_libraries(bar ${PROTOBUF_LIBRARIES})

NOTE: You may need to link against pthreads, depending

on the platform.

NOTE: The PROTOBUF_GENERATE_CPP macro & add_executable() or add_library()

calls only work properly within the same directory.

FindPythonInterp Find python interpreter

This module finds if Python interpreter is installed and deter- mines where the executables are. This code sets the following variables:

PYTHONINTERP_FOUND - Was the Python executable found PYTHON_EXECUTABLE - path to the Python interpreter

PYTHON_VERSION_STRING - Python version found e.g. 2.5.2 PYTHON_VERSION_MAJOR - Python major version found e.g. 2 PYTHON_VERSION_MINOR - Python minor version found e.g. 5 PYTHON_VERSION_PATCH - Python patch version found e.g. 2

The Python_ADDITIONAL_VERSIONS variable can be used to specify a list of version numbers that should be taken into account when searching for Python. You need to set this variable before call- ing find_package(PythonInterp).

FindPythonLibs Find python libraries

This module finds if Python is installed and determines where the include files and libraries are. It also determines what the name of the library is. This code sets the following variables:

PYTHONLIBS_FOUND - have the Python libs been found PYTHON_LIBRARIES - path to the python library PYTHON_INCLUDE_PATH - path to where Python.h is found (deprecated) PYTHON_INCLUDE_DIRS - path to where Python.h is found PYTHON_DEBUG_LIBRARIES - path to the debug library (deprecated) PYTHONLIBS_VERSION_STRING - version of the Python libs found (since CMake 2.8.8)

The Python_ADDITIONAL_VERSIONS variable can be used to specify a list of version numbers that should be taken into account when searching for Python. You need to set this variable before call- ing find_package(PythonLibs).

If youd like to specify the installation of Python to use, you should modify the following cache variables:

PYTHON_LIBRARY - path to the python library PYTHON_INCLUDE_DIR - path to where Python.h is found

FindQt Searches for all installed versions of Qt.

This should only be used if your project can work with multiple versions of Qt. If not, you should just directly use FindQt4 or FindQt3. If multiple versions of Qt are found on the machine, then The user must set the option DESIRED_QT_VERSION to the ver- sion they want to use. If only one version of qt is found on the machine, then the DESIRED_QT_VERSION is set to that version and the matching FindQt3 or FindQt4 module is included. Once the user sets DESIRED_QT_VERSION, then the FindQt3 or FindQt4 module is included.

QT_REQUIRED if this is set to TRUE then if CMake can not find Qt4 or Qt3 an error is raised and a message is sent to the user.

DESIRED_QT_VERSION OPTION is created QT4_INSTALLED is set to TRUE if qt4 is found. QT3_INSTALLED is set to TRUE if qt3 is found.

FindQt3 Locate Qt include paths and libraries

This module defines:

QT_INCLUDE_DIR - where to find qt.h, etc. QT_LIBRARIES - the libraries to link against to use Qt. QT_DEFINITIONS - definitions to use when compiling code that uses Qt. QT_FOUND - If false, dont try to use Qt. QT_VERSION_STRING - the version of Qt found

If you need the multithreaded version of Qt, set QT_MT_REQUIRED to TRUE

Also defined, but not for general use are:

QT_MOC_EXECUTABLE, where to find the moc tool. QT_UIC_EXECUTABLE, where to find the uic tool. QT_QT_LIBRARY, where to find the Qt library. QT_QTMAIN_LIBRARY, where to find the qtmain library. This is only required by Qt3 on Windows.

FindQt4 Find Qt 4

This module can be used to find Qt4. The most important issue is that the Qt4 qmake is available via the system path. This qmake is then used to detect basically everything else. This module defines a number of key variables and macros. The variable QT_USE_FILE is set which is the path to a CMake file that can be included to compile Qt 4 applications and libraries. It sets up the compilation environment for include directories, preprocessor defines and populates a QT_LIBRARIES variable.

Typical usage could be something like:

find_package(Qt4 4.4.3 REQUIRED QtCore QtGui QtXml) include(${QT_USE_FILE}) add_executable(myexe main.cpp) target_link_libraries(myexe ${QT_LIBRARIES})

The minimum required version can be specified using the standard find_package()-syntax (see example above). For compatibility with older versions of FindQt4.cmake it is also possible to set the variable QT_MIN_VERSION to the minimum required version of Qt4 before the find_package(Qt4) command. If both are used, the version used in the find_package() command overrides the one from QT_MIN_VERSION.

When using the components argument, QT_USE_QT* variables are automatically set for the QT_USE_FILE to pick up. If one wishes to manually set them, the available ones to set include:

QT_DONT_USE_QTCORE QT_DONT_USE_QTGUI QT_USE_QT3SUPPORT QT_USE_QTASSISTANT QT_USE_QAXCONTAINER QT_USE_QAXSERVER QT_USE_QTDESIGNER QT_USE_QTMOTIF QT_USE_QTMAIN QT_USE_QTMULTIMEDIA QT_USE_QTNETWORK QT_USE_QTNSPLUGIN QT_USE_QTOPENGL QT_USE_QTSQL QT_USE_QTXML QT_USE_QTSVG QT_USE_QTTEST QT_USE_QTUITOOLS QT_USE_QTDBUS QT_USE_QTSCRIPT QT_USE_QTASSISTANTCLIENT QT_USE_QTHELP QT_USE_QTWEBKIT QT_USE_QTXMLPATTERNS QT_USE_PHONON QT_USE_QTSCRIPTTOOLS QT_USE_QTDECLARATIVE

QT_USE_IMPORTED_TARGETS If this variable is set to TRUE, FindQt4.cmake will create imported library targets for the various Qt libraries and set the library variables like QT_QTCORE_LIBRARY to point at these imported targets instead of the library file on disk. This provides much better handling of the release and debug versions of the Qt libraries and is also always backwards compatible, except for the case that dependencies of libraries are exported, these will then also list the names of the imported targets as dependency and not the file location on disk. This is much more flexible, but requires that FindQt4.cmake is executed before such an exported dependency file is processed.

Note that if using IMPORTED targets, the qtmain.lib static library is automatically linked on Windows. To disable that globally, set the QT4_NO_LINK_QTMAIN variable before finding Qt4. To disable that for a particular executable, set the QT4_NO_LINK_QTMAIN target property to True on the executable.

QT_INCLUDE_DIRS_NO_SYSTEM If this variable is set to TRUE, the Qt include directories in the QT_USE_FILE will NOT have the SYSTEM keyword set.

There are also some files that need processing by some Qt tools such as moc and uic. Listed below are macros that may be used to process those files.

macro QT4_WRAP_CPP(outfiles inputfile ... OPTIONS ...) create moc code from a list of files containing Qt class with the Q_OBJECT declaration. Per-directory preprocessor definitions are also added. Options may be given to moc, such as those found when executing "moc -help".

macro QT4_WRAP_UI(outfiles inputfile ... OPTIONS ...) create code from a list of Qt designer ui files. Options may be given to uic, such as those found when executing "uic -help"

macro QT4_ADD_RESOURCES(outfiles inputfile ... OPTIONS ...) create code from a list of Qt resource files. Options may be given to rcc, such as those found when executing "rcc -help"

macro QT4_GENERATE_MOC(inputfile outputfile ) creates a rule to run moc on infile and create outfile. Use this if for some reason QT4_WRAP_CPP() isnt appropriate, e.g. because you need a custom filename for the moc file or something similar.

macro QT4_AUTOMOC(sourcefile1 sourcefile2 ... ) The qt4_automoc macro is obsolete. Use the CMAKE_AUTOMOC feature instead. This macro is still experimental. It can be used to have moc automatically handled. So if you have the files foo.h and foo.cpp, and in foo.h a a class uses the Q_OBJECT macro, moc has to run on it. If you dont want to use QT4_WRAP_CPP() (which is reliable and mature), you can insert #include "foo.moc" in foo.cpp and then give foo.cpp as argument to QT4_AUTOMOC(). This will the scan all listed files at cmake-time for such included moc files and if it finds them cause a rule to be generated to run moc at build time on the accompanying header file foo.h. If a source file has the SKIP_AUTOMOC property set it will be ignored by this macro.

You should have a look on the AUTOMOC property for targets to achieve the same results.

macro QT4_ADD_DBUS_INTERFACE(outfiles interface basename) Create the interface header and implementation files with the given basename from the given interface xml file and add it to the list of sources.

You can pass additional parameters to the qdbusxml2cpp call by setting properties on the input file:

INCLUDE the given file will be included in the generate interface header

CLASSNAME the generated class is named accordingly

NO_NAMESPACE the generated class is not wrapped in a namespace

macro QT4_ADD_DBUS_INTERFACES(outfiles inputfile ... ) Create the interface header and implementation files for all listed interface xml files. The basename will be automatically determined from the name of the xml file.

The source file properties described for QT4_ADD_DBUS_INTERFACE also apply here.

macro QT4_ADD_DBUS_ADAPTOR(outfiles xmlfile parentheader parentclassname [basename] [classname]) create a dbus adaptor (header and implementation file) from the xml file describing the interface, and add it to the list of sources. The adaptor forwards the calls to a parent class, defined in parentheader and named parentclassname. The name of the generated files will be <basename>adaptor.{cpp,h} where basename defaults to the basename of the xml file. If <classname> is provided, then it will be used as the classname of the adaptor itself.

macro QT4_GENERATE_DBUS_INTERFACE( header [interfacename] OPTIONS ...) generate the xml interface file from the given header. If the optional argument interfacename is omitted, the name of the interface file is constructed from the basename of the header with the suffix .xml appended. Options may be given to qdbuscpp2xml, such as those found when executing "qdbuscpp2xml --help"

macro QT4_CREATE_TRANSLATION( qm_files directories ... sources ... ts_files ... OPTIONS ...) out: qm_files in: directories sources ts_files options: flags to pass to lupdate, such as -extensions to specify extensions for a directory scan. generates commands to create .ts (vie lupdate) and .qm (via lrelease) - files from directories and/or sources. The ts files are created and/or updated in the source tree (unless given with full paths). The qm files are generated in the build tree. Updating the translations can be done by adding the qm_files to the source list of your library/executable, so they are always updated, or by adding a custom target to control when they get updated/generated.

macro QT4_ADD_TRANSLATION( qm_files ts_files ... ) out: qm_files in: ts_files generates commands to create .qm from .ts - files. The generated filenames can be found in qm_files. The ts_files must exist and are not updated in any way.

function QT4_USE_MODULES( target [link_type] modules...)

This function is obsolete. Use target_link_libraries with IMPORTED targets instead. Make <target> use the <modules> from Qt. Using a Qt module means to link to the library, add the relevant include directories for the module, and add the relevant compiler defines for using the module. Modules are roughly equivalent to components of Qt4, so usage would be something like: qt4_use_modules(myexe Core Gui Declarative) to use QtCore, QtGui and QtDeclarative. The optional <link_type> argument can be specified as either LINK_PUBLIC or LINK_PRIVATE to specify the same argument to the target_link_libraries call.

Below is a detailed list of variables that FindQt4.cmake sets. QT_FOUND If false, dont try to use Qt. Qt4_FOUND If false, dont try to use Qt 4. QT4_FOUND If false, dont try to use Qt 4. This variable is for compatibility only.

QT_VERSION_MAJOR The major version of Qt found. QT_VERSION_MINOR The minor version of Qt found. QT_VERSION_PATCH The patch version of Qt found.

QT_EDITION Set to the edition of Qt (i.e. DesktopLight) QT_EDITION_DESKTOPLIGHT True if QT_EDITION == DesktopLight QT_QTCORE_FOUND True if QtCore was found. QT_QTGUI_FOUND True if QtGui was found. QT_QT3SUPPORT_FOUND True if Qt3Support was found. QT_QTASSISTANT_FOUND True if QtAssistant was found. QT_QTASSISTANTCLIENT_FOUND True if QtAssistantClient was found. QT_QAXCONTAINER_FOUND True if QAxContainer was found (Windows only). QT_QAXSERVER_FOUND True if QAxServer was found (Windows only). QT_QTDBUS_FOUND True if QtDBus was found. QT_QTDESIGNER_FOUND True if QtDesigner was found. QT_QTDESIGNERCOMPONENTS True if QtDesignerComponents was found. QT_QTHELP_FOUND True if QtHelp was found. QT_QTMOTIF_FOUND True if QtMotif was found. QT_QTMULTIMEDIA_FOUND True if QtMultimedia was found (since Qt 4.6.0). QT_QTNETWORK_FOUND True if QtNetwork was found. QT_QTNSPLUGIN_FOUND True if QtNsPlugin was found. QT_QTOPENGL_FOUND True if QtOpenGL was found. QT_QTSQL_FOUND True if QtSql was found. QT_QTSVG_FOUND True if QtSvg was found. QT_QTSCRIPT_FOUND True if QtScript was found. QT_QTSCRIPTTOOLS_FOUND True if QtScriptTools was found. QT_QTTEST_FOUND True if QtTest was found. QT_QTUITOOLS_FOUND True if QtUiTools was found. QT_QTWEBKIT_FOUND True if QtWebKit was found. QT_QTXML_FOUND True if QtXml was found. QT_QTXMLPATTERNS_FOUND True if QtXmlPatterns was found. QT_PHONON_FOUND True if phonon was found. QT_QTDECLARATIVE_FOUND True if QtDeclarative was found.

QT_MAC_USE_COCOA For Mac OS X, its whether Cocoa or Carbon is used. In general, this should not be used, but its useful when having platform specific code.

QT_DEFINITIONS Definitions to use when compiling code that uses Qt. You do not need to use this if you include QT_USE_FILE. The QT_USE_FILE will also define QT_DEBUG and QT_NO_DEBUG to fit your current build type. Those are not contained in QT_DEFINITIONS.

QT_INCLUDES List of paths to all include directories of Qt4 QT_INCLUDE_DIR and QT_QTCORE_INCLUDE_DIR are always in this variable even if NOTFOUND, all other INCLUDE_DIRS are only added if they are found. You do not need to use this if you include QT_USE_FILE.

Include directories for the Qt modules are listed here. You do not need to use these variables if you include QT_USE_FILE.

QT_INCLUDE_DIR Path to "include" of Qt4 QT_QT3SUPPORT_INCLUDE_DIR Path to "include/Qt3Support" QT_QTASSISTANT_INCLUDE_DIR Path to "include/QtAssistant" QT_QTASSISTANTCLIENT_INCLUDE_DIR Path to "include/QtAssistant" QT_QAXCONTAINER_INCLUDE_DIR Path to "include/ActiveQt" (Windows only) QT_QAXSERVER_INCLUDE_DIR Path to "include/ActiveQt" (Windows only) QT_QTCORE_INCLUDE_DIR Path to "include/QtCore" QT_QTDBUS_INCLUDE_DIR Path to "include/QtDBus" QT_QTDESIGNER_INCLUDE_DIR Path to "include/QtDesigner" QT_QTDESIGNERCOMPONENTS_INCLUDE_DIR Path to "include/QtDesigner" QT_QTGUI_INCLUDE_DIR Path to "include/QtGui" QT_QTHELP_INCLUDE_DIR Path to "include/QtHelp" QT_QTMOTIF_INCLUDE_DIR Path to "include/QtMotif" QT_QTMULTIMEDIA_INCLUDE_DIR Path to "include/QtMultimedia" QT_QTNETWORK_INCLUDE_DIR Path to "include/QtNetwork" QT_QTNSPLUGIN_INCLUDE_DIR Path to "include/QtNsPlugin" QT_QTOPENGL_INCLUDE_DIR Path to "include/QtOpenGL" QT_QTSCRIPT_INCLUDE_DIR Path to "include/QtScript" QT_QTSQL_INCLUDE_DIR Path to "include/QtSql" QT_QTSVG_INCLUDE_DIR Path to "include/QtSvg" QT_QTTEST_INCLUDE_DIR Path to "include/QtTest" QT_QTWEBKIT_INCLUDE_DIR Path to "include/QtWebKit" QT_QTXML_INCLUDE_DIR Path to "include/QtXml" QT_QTXMLPATTERNS_INCLUDE_DIR Path to "include/QtXmlPatterns" QT_PHONON_INCLUDE_DIR Path to "include/phonon" QT_QTSCRIPTTOOLS_INCLUDE_DIR Path to "include/QtScriptTools" QT_QTDECLARATIVE_INCLUDE_DIR Path to "include/QtDeclarative"

The Qt toolkit may contain both debug and release libraries. In that case, the following library variables will contain both. You do not need to use these variables if you include QT_USE_FILE, and use QT_LIBRARIES.

QT_QT3SUPPORT_LIBRARY The Qt3Support library QT_QTASSISTANT_LIBRARY The QtAssistant library QT_QTASSISTANTCLIENT_LIBRARY The QtAssistantClient library QT_QAXCONTAINER_LIBRARY The QAxContainer library (Windows only) QT_QAXSERVER_LIBRARY The QAxServer library (Windows only) QT_QTCORE_LIBRARY The QtCore library QT_QTDBUS_LIBRARY The QtDBus library QT_QTDESIGNER_LIBRARY The QtDesigner library QT_QTDESIGNERCOMPONENTS_LIBRARY The QtDesignerComponents library QT_QTGUI_LIBRARY The QtGui library QT_QTHELP_LIBRARY The QtHelp library QT_QTMOTIF_LIBRARY The QtMotif library QT_QTMULTIMEDIA_LIBRARY The QtMultimedia library QT_QTNETWORK_LIBRARY The QtNetwork library QT_QTNSPLUGIN_LIBRARY The QtNsPLugin library QT_QTOPENGL_LIBRARY The QtOpenGL library QT_QTSCRIPT_LIBRARY The QtScript library QT_QTSQL_LIBRARY The QtSql library QT_QTSVG_LIBRARY The QtSvg library QT_QTTEST_LIBRARY The QtTest library QT_QTUITOOLS_LIBRARY The QtUiTools library QT_QTWEBKIT_LIBRARY The QtWebKit library QT_QTXML_LIBRARY The QtXml library QT_QTXMLPATTERNS_LIBRARY The QtXmlPatterns library QT_QTMAIN_LIBRARY The qtmain library for Windows QT_PHONON_LIBRARY The phonon library QT_QTSCRIPTTOOLS_LIBRARY The QtScriptTools library

also defined, but NOT for general use are

QT_MOC_EXECUTABLE Where to find the moc tool. QT_UIC_EXECUTABLE Where to find the uic tool. QT_UIC3_EXECUTABLE Where to find the uic3 tool. QT_RCC_EXECUTABLE Where to find the rcc tool QT_DBUSCPP2XML_EXECUTABLE Where to find the qdbuscpp2xml tool. QT_DBUSXML2CPP_EXECUTABLE Where to find the qdbusxml2cpp tool.

QT_DESIGNER_EXECUTABLE Where to find the Qt designer tool. QT_LINGUIST_EXECUTABLE Where to find the Qt linguist tool.

These are around for backwards compatibility they will be set

QT_WRAP_CPP Set true if QT_MOC_EXECUTABLE is found QT_WRAP_UI Set true if QT_UIC_EXECUTABLE is found

These variables do _NOT_ have any effect anymore (compared to FindQt.cmake)

QT_MT_REQUIRED Qt4 is now always multithreaded

These variables are set to "" Because Qt structure changed (They make no sense in Qt4)

QT_QT_LIBRARY Qt-Library is now split

FindQuickTime

Locate QuickTime This module defines QUICKTIME_LIBRARY QUICK- TIME_FOUND, if false, do not try to link to gdal QUICK- TIME_INCLUDE_DIR, where to find the headers

$QUICKTIME_DIR is an environment variable that would correspond to the ./configure --prefix=$QUICKTIME_DIR

Created by Eric Wing.

FindRTI Try to find M&S HLA RTI libraries

This module finds if any HLA RTI is installed and locates the standard RTI include files and libraries.

RTI is a simulation infrastructure standardized by IEEE and SISO. It has a well defined C++ API that assures that simulation applications are independent on a particular RTI implementation.

http://en.wikipedia.org/wiki/Run-Time_Infrastructure_(simulation)

This code sets the following variables:

RTI_INCLUDE_DIR = the directory where RTI includes file are found RTI_LIBRARIES = The libraries to link against to use RTI RTI_DEFINITIONS = -DRTI_USES_STD_FSTREAM RTI_FOUND = Set to FALSE if any HLA RTI was not found

Report problems to <certi-devel@nongnu.org>

FindRuby Find Ruby

This module finds if Ruby is installed and determines where the include files and libraries are. Ruby 1.8 and 1.9 are supported.

The minimum required version of Ruby can be specified using the standard syntax, e.g. find_package(Ruby 1.8)

It also determines what the name of the library is. This code sets the following variables:

RUBY_EXECUTABLE = full path to the ruby binary RUBY_INCLUDE_DIRS = include dirs to be used when using the ruby library RUBY_LIBRARY = full path to the ruby library RUBY_VERSION = the version of ruby which was found, e.g. "1.8.7" RUBY_FOUND = set to true if ruby ws found successfully

RUBY_INCLUDE_PATH = same as RUBY_INCLUDE_DIRS, only provided for compatibility reasons, dont use it

FindSDL Locate SDL library

This module defines

SDL_LIBRARY, the name of the library to link against SDL_FOUND, if false, do not try to link to SDL SDL_INCLUDE_DIR, where to find SDL.h SDL_VERSION_STRING, human-readable string containing the version of SDL

This module responds to the the flag:

SDL_BUILDING_LIBRARY If this is defined, then no SDL_main will be linked in because only applications need main(). Otherwise, it is assumed you are building an application and this module will attempt to locate and set the the proper link flags as part of the returned SDL_LIBRARY variable.

Dont forget to include SDLmain.h and SDLmain.m your project for the OS X framework based version. (Other versions link to -lSDL- main which this module will try to find on your behalf.) Also for OS X, this module will automatically add the -framework Cocoa on your behalf.

Additional Note: If you see an empty SDL_LIBRARY_TEMP in your configuration and no SDL_LIBRARY, it means CMake did not find your SDL library (SDL.dll, libsdl.so, SDL.framework, etc). Set SDL_LIBRARY_TEMP to point to your SDL library, and configure again. Similarly, if you see an empty SDLMAIN_LIBRARY, you should set this value as appropriate. These values are used to generate the final SDL_LIBRARY variable, but when these values are unset, SDL_LIBRARY does not get created.

$SDLDIR is an environment variable that would correspond to the ./configure --prefix=$SDLDIR used in building SDL. l.e.galup 9-20-02

Modified by Eric Wing. Added code to assist with automated building by using environmental variables and providing a more controlled/consistent search behavior. Added new modifications to recognize OS X frameworks and additional Unix paths (FreeBSD, etc). Also corrected the header search path to follow "proper" SDL guidelines. Added a search for SDLmain which is needed by some platforms. Added a search for threads which is needed by some platforms. Added needed compile switches for MinGW.

On OSX, this will prefer the Framework version (if found) over others. People will have to manually change the cache values of SDL_LIBRARY to override this selection or set the CMake environ- ment CMAKE_INCLUDE_PATH to modify the search paths.

Note that the header path has changed from SDL/SDL.h to just SDL.h This needed to change because "proper" SDL convention is #include "SDL.h", not <SDL/SDL.h>. This is done for portability reasons because not all systems place things in SDL/ (see FreeBSD).

FindSDL_image Locate SDL_image library

This module defines:

SDL_IMAGE_LIBRARIES, the name of the library to link against SDL_IMAGE_INCLUDE_DIRS, where to find the headers SDL_IMAGE_FOUND, if false, do not try to link against SDL_IMAGE_VERSION_STRING - human-readable string containing the version of SDL_image

For backward compatiblity the following variables are also set:

SDLIMAGE_LIBRARY (same value as SDL_IMAGE_LIBRARIES) SDLIMAGE_INCLUDE_DIR (same value as SDL_IMAGE_INCLUDE_DIRS) SDLIMAGE_FOUND (same value as SDL_IMAGE_FOUND)

$SDLDIR is an environment variable that would correspond to the ./configure --prefix=$SDLDIR used in building SDL.

Created by Eric Wing. This was influenced by the FindSDL.cmake module, but with modifications to recognize OS X frameworks and additional Unix paths (FreeBSD, etc).

FindSDL_mixer Locate SDL_mixer library

This module defines:

SDL_MIXER_LIBRARIES, the name of the library to link against SDL_MIXER_INCLUDE_DIRS, where to find the headers SDL_MIXER_FOUND, if false, do not try to link against SDL_MIXER_VERSION_STRING - human-readable string containing the version of SDL_mixer

For backward compatiblity the following variables are also set:

SDLMIXER_LIBRARY (same value as SDL_MIXER_LIBRARIES) SDLMIXER_INCLUDE_DIR (same value as SDL_MIXER_INCLUDE_DIRS) SDLMIXER_FOUND (same value as SDL_MIXER_FOUND)

$SDLDIR is an environment variable that would correspond to the ./configure --prefix=$SDLDIR used in building SDL.

FindSDL_sound Locates the SDL_sound library

This module depends on SDL being found and must be called AFTER FindSDL.cmake is called.

This module defines

SDL_SOUND_INCLUDE_DIR, where to find SDL_sound.h SDL_SOUND_FOUND, if false, do not try to link to SDL_sound SDL_SOUND_LIBRARIES, this contains the list of libraries that you need to link against. This is a read-only variable and is marked INTERNAL. SDL_SOUND_EXTRAS, this is an optional variable for you to add your own flags to SDL_SOUND_LIBRARIES. This is prepended to SDL_SOUND_LIBRARIES. This is available mostly for cases this module failed to anticipate for and you must add additional flags. This is marked as ADVANCED. SDL_SOUND_VERSION_STRING, human-readable string containing the version of SDL_sound

This module also defines (but you shouldn t need to use directly)

SDL_SOUND_LIBRARY, the name of just the SDL_sound library you would link against. Use SDL_SOUND_LIBRARIES for you link instructions and not this one.

And might define the following as needed

MIKMOD_LIBRARY MODPLUG_LIBRARY OGG_LIBRARY VORBIS_LIBRARY SMPEG_LIBRARY FLAC_LIBRARY SPEEX_LIBRARY

Typically, you should not use these variables directly, and you should use SDL_SOUND_LIBRARIES which contains SDL_SOUND_LIBRARY and the other audio libraries (if needed) to successfully com- pile on your system.

Created by Eric Wing. This module is a bit more complicated than the other FindSDL* family modules. The reason is that SDL_sound can be compiled in a large variety of different ways which are independent of platform. SDL_sound may dynamically link against other 3rd party libraries to get additional codec support, such as Ogg Vorbis, SMPEG, ModPlug, MikMod, FLAC, Speex, and poten- tially others. Under some circumstances which I dont fully understand, there seems to be a requirement that dependent libraries of libraries you use must also be explicitly linked against in order to successfully compile. SDL_sound does not currently have any system in place to know how it was compiled. So this CMake module does the hard work in trying to discover which 3rd party libraries are required for building (if any). This module uses a brute force approach to create a test program that uses SDL_sound, and then tries to build it. If the build fails, it parses the error output for known symbol names to fig- ure out which libraries are needed.

Responds to the $SDLDIR and $SDLSOUNDDIR environmental variable that would correspond to the ./configure --prefix=$SDLDIR used in building SDL.

On OSX, this will prefer the Framework version (if found) over others. People will have to manually change the cache values of SDL_LIBRARY to override this selectionor set the CMake environ- ment CMAKE_INCLUDE_PATH to modify the search paths.

FindSDL_ttf Locate SDL_ttf library

This module defines:

SDL_TTF_LIBRARIES, the name of the library to link against SDL_TTF_INCLUDE_DIRS, where to find the headers SDL_TTF_FOUND, if false, do not try to link against SDL_TTF_VERSION_STRING - human-readable string containing the version of SDL_ttf

For backward compatiblity the following variables are also set:

SDLTTF_LIBRARY (same value as SDL_TTF_LIBRARIES) SDLTTF_INCLUDE_DIR (same value as SDL_TTF_INCLUDE_DIRS) SDLTTF_FOUND (same value as SDL_TTF_FOUND)

$SDLDIR is an environment variable that would correspond to the ./configure --prefix=$SDLDIR used in building SDL.

Created by Eric Wing. This was influenced by the FindSDL.cmake module, but with modifications to recognize OS X frameworks and additional Unix paths (FreeBSD, etc).

FindSWIG Find SWIG

This module finds an installed SWIG. It sets the following variables:

SWIG_FOUND - set to true if SWIG is found SWIG_DIR - the directory where swig is installed SWIG_EXECUTABLE - the path to the swig executable SWIG_VERSION - the version number of the swig executable

The minimum required version of SWIG can be specified using the standard syntax, e.g. find_package(SWIG 1.1)

All information is collected from the SWIG_EXECUTABLE so the version to be found can be changed from the command line by means of setting SWIG_EXECUTABLE

FindSelfPackers Find upx

This module looks for some executable packers (i.e. software that compress executables or shared libs into on-the-fly self-extracting executables or shared libs. Examples:

UPX: http://wildsau.idv.uni-linz.ac.at/mfx/upx.html

FindSquish -- Typical Use

This module can be used to find Squish. Currently Squish ver- sions 3 and 4 are supported.

SQUISH_FOUND If false, don t try to use Squish SQUISH_VERSION The full version of Squish found SQUISH_VERSION_MAJOR The major version of Squish found SQUISH_VERSION_MINOR The minor version of Squish found SQUISH_VERSION_PATCH The patch version of Squish found

SQUISH_INSTALL_DIR The Squish installation directory (containing bin, lib, etc) SQUISH_SERVER_EXECUTABLE The squishserver executable SQUISH_CLIENT_EXECUTABLE The squishrunner executable

SQUISH_INSTALL_DIR_FOUND Was the install directory found? SQUISH_SERVER_EXECUTABLE_FOUND Was the server executable found? SQUISH_CLIENT_EXECUTABLE_FOUND Was the client executable found?

It provides the function squish_v4_add_test() for adding a squish test to cmake using Squish 4.x:

squish_v4_add_test(cmakeTestName AUT targetName SUITE suiteName TEST squishTestName [SETTINGSGROUP group] [PRE_COMMAND command] [POST_COMMAND command] )

The arguments have the following meaning:

cmakeTestName: this will be used as the first argument for add_test() AUT targetName: the name of the cmake target which will be used as AUT, i.e. the executable which will be tested. SUITE suiteName: this is either the full path to the squish suite, or just the last directory of the suite, i.e. the suite name. In this case the CMakeLists.txt which calls squish_add_test() must be located in the parent directory of the suite directory. TEST squishTestName: the name of the squish test, i.e. the name of the subdirectory of the test inside the suite directory. SETTINGSGROUP group: if specified, the given settings group will be used for executing the test. If not specified, the groupname will be "CTest_<username>" PRE_COMMAND command: if specified, the given command will be executed before starting the squish test. POST_COMMAND command: same as PRE_COMMAND, but after the squish test has been executed.

enable_testing() find_package(Squish 4.0) if (SQUISH_FOUND) squish_v4_add_test(myTestName AUT myApp SUITE ${CMAKE_SOURCE_DIR}/tests/mySuite TEST someSquishTest SETTINGSGROUP myGroup ) endif ()

For users of Squish version 3.x the macro squish_v3_add_test() is provided:

squish_v3_add_test(testName applicationUnderTest testCase envVars testWrapper) Use this macro to add a test using Squish 3.x.

enable_testing() find_package(Squish) if (SQUISH_FOUND) squish_v3_add_test(myTestName myApplication testCase envVars testWrapper) endif ()

macro SQUISH_ADD_TEST(testName applicationUnderTest testCase envVars testWrapper)

This is deprecated. Use SQUISH_V3_ADD_TEST() if you are using Squish 3.x instead.

FindSubversion Extract information from a subversion working copy

The module defines the following variables:

Subversion_SVN_EXECUTABLE - path to svn command line client Subversion_VERSION_SVN - version of svn command line client Subversion_FOUND - true if the command line client was found SUBVERSION_FOUND - same as Subversion_FOUND, set for compatiblity reasons

The minimum required version of Subversion can be specified using the standard syntax, e.g. find_package(Subversion 1.4)

If the command line client executable is found two macros are defined:

Subversion_WC_INFO(<dir> <var-prefix>) Subversion_WC_LOG(<dir> <var-prefix>)

Subversion_WC_INFO extracts information of a subversion working copy at a given location. This macro defines the following vari- ables:

<var-prefix>_WC_URL - url of the repository (at <dir>) <var-prefix>_WC_ROOT - root url of the repository <var-prefix>_WC_REVISION - current revision <var-prefix>_WC_LAST_CHANGED_AUTHOR - author of last commit <var-prefix>_WC_LAST_CHANGED_DATE - date of last commit <var-prefix>_WC_LAST_CHANGED_REV - revision of last commit <var-prefix>_WC_INFO - output of command svn info <dir>

Subversion_WC_LOG retrieves the log message of the base revision of a subversion working copy at a given location. This macro defines the variable:

<var-prefix>_LAST_CHANGED_LOG - last log of base revision

Example usage:

find_package(Subversion) if(SUBVERSION_FOUND) Subversion_WC_INFO(${PROJECT_SOURCE_DIR} Project) message("Current revision is ${Project_WC_REVISION}") Subversion_WC_LOG(${PROJECT_SOURCE_DIR} Project) message("Last changed log is ${Project_LAST_CHANGED_LOG}") endif()

FindTCL TK_INTERNAL_PATH was removed.

This module finds if Tcl is installed and determines where the include files and libraries are. It also determines what the name of the library is. This code sets the following variables:

TCL_FOUND = Tcl was found TK_FOUND = Tk was found TCLTK_FOUND = Tcl and Tk were found TCL_LIBRARY = path to Tcl library (tcl tcl80) TCL_INCLUDE_PATH = path to where tcl.h can be found TCL_TCLSH = path to tclsh binary (tcl tcl80) TK_LIBRARY = path to Tk library (tk tk80 etc) TK_INCLUDE_PATH = path to where tk.h can be found TK_WISH = full path to the wish executable

In an effort to remove some clutter and clear up some issues for people who are not necessarily Tcl/Tk gurus/developpers, some variables were moved or removed. Changes compared to CMake 2.4 are:

=> they were only useful for people writing Tcl/Tk extensions. => these libs are not packaged by default with Tcl/Tk distributions. Even when Tcl/Tk is built from source, several flavors of debug libs are created and there is no real reason to pick a single one specifically (say, amongst tcl84g, tcl84gs, or tcl84sgx). Let s leave that choice to the user by allowing him to assign TCL_LIBRARY to any Tcl library, debug or not. => this ended up being only a Win32 variable, and there is a lot of confusion regarding the location of this file in an installed Tcl/Tk tree anyway (see 8.5 for example). If you need the internal path at this point it is safer you ask directly where the *source* tree is and dig from there.

Findosg

NOTE: It is highly recommended that you use the new FindOpen- SceneGraph.cmake introduced in CMake 2.6.3 and not use this Find module directly.

This is part of the Findosg* suite used to find OpenSceneGraph components. Each component is separate and you must opt in to each module. You must also opt into OpenGL and OpenThreads (and Producer if needed) as these modules wont do it for you. This is to allow you control over your own system piece by piece in case you need to opt out of certain components or change the Find behavior for a particular module (perhaps because the default FindOpenGL.cmake module doesn t work with your system as an example). If you want to use a more convenient module that includes everything, use the FindOpenSceneGraph.cmake instead of the Findosg*.cmake modules.

FindosgProducer

This is part of the Findosg* suite used to find OpenSceneGraph components. Each component is separate and you must opt in to each module. You must also opt into OpenGL and OpenThreads (and Producer if needed) as these modules wont do it for you. This is to allow you control over your own system piece by piece in case you need to opt out of certain components or change the Find behavior for a particular module (perhaps because the default FindOpenGL.cmake module doesn t work with your system as an example). If you want to use a more convenient module that includes everything, use the FindOpenSceneGraph.cmake instead of the Findosg*.cmake modules.

Findosg_functions

This CMake file contains two macros to assist with searching for OSG libraries and nodekits. Please see FindOpenSceneGraph.cmake for full documentation.

FindwxWidgets Find a wxWidgets (a.k.a., wxWindows) installation.

This module finds if wxWidgets is installed and selects a default configuration to use. wxWidgets is a modular library. To specify the modules that you will use, you need to name them as components to the package:

find_package(wxWidgets COMPONENTS core base ...)

There are two search branches: a windows style and a unix style. For windows, the following variables are searched for and set to defaults in case of multiple choices. Change them if the defaults are not desired (i.e., these are the only variables you should change to select a configuration):

wxWidgets_ROOT_DIR - Base wxWidgets directory (e.g., C:/wxWidgets-2.6.3). wxWidgets_LIB_DIR - Path to wxWidgets libraries (e.g., C:/wxWidgets-2.6.3/lib/vc_lib). wxWidgets_CONFIGURATION - Configuration to use (e.g., msw, mswd, mswu, mswunivud, etc.) wxWidgets_EXCLUDE_COMMON_LIBRARIES - Set to TRUE to exclude linking of commonly required libs (e.g., png tiff jpeg zlib regex expat).

For unix style it uses the wx-config utility. You can select between debug/release, unicode/ansi, universal/non-universal, and static/shared in the QtDialog or ccmake interfaces by turn- ing ON/OFF the following variables:

wxWidgets_USE_DEBUG wxWidgets_USE_UNICODE wxWidgets_USE_UNIVERSAL wxWidgets_USE_STATIC

There is also a wxWidgets_CONFIG_OPTIONS variable for all other options that need to be passed to the wx-config utility. For example, to use the base toolkit found in the /usr/local path, set the variable (before calling the FIND_PACKAGE command) as such:

set(wxWidgets_CONFIG_OPTIONS --toolkit=base --prefix=/usr)

The following are set after the configuration is done for both windows and unix style:

wxWidgets_FOUND - Set to TRUE if wxWidgets was found. wxWidgets_INCLUDE_DIRS - Include directories for WIN32 i.e., where to find "wx/wx.h" and "wx/setup.h"; possibly empty for unices. wxWidgets_LIBRARIES - Path to the wxWidgets libraries. wxWidgets_LIBRARY_DIRS - compile time link dirs, useful for rpath on UNIX. Typically an empty string in WIN32 environment. wxWidgets_DEFINITIONS - Contains defines required to compile/link against WX, e.g. WXUSINGDLL wxWidgets_DEFINITIONS_DEBUG- Contains defines required to compile/link against WX debug builds, e.g. __WXDEBUG__ wxWidgets_CXX_FLAGS - Include dirs and compiler flags for unices, empty on WIN32. Essentially " wx-config --cxxflags". wxWidgets_USE_FILE - Convenience include file.

Sample usage:

# Note that for MinGW users the order of libs is important! find_package(wxWidgets COMPONENTS net gl core base) if(wxWidgets_FOUND) include(${wxWidgets_USE_FILE}) # and for each of your dependent executable/library targets: target_link_libraries(<YourTarget> ${wxWidgets_LIBRARIES}) endif()

If wxWidgets is required (i.e., not an optional part):

find_package(wxWidgets REQUIRED net gl core base) include(${wxWidgets_USE_FILE}) # and for each of your dependent executable/library targets: target_link_libraries(<YourTarget> ${wxWidgets_LIBRARIES})

FindwxWindows Find wxWindows (wxWidgets) installation

This module finds if wxWindows/wxWidgets is installed and deter- mines where the include files and libraries are. It also deter- mines what the name of the library is. Please note this file is DEPRECATED and replaced by FindwxWidgets.cmake. This code sets the following variables:

WXWINDOWS_FOUND = system has WxWindows WXWINDOWS_LIBRARIES = path to the wxWindows libraries on Unix/Linux with additional linker flags from "wx-config --libs" CMAKE_WXWINDOWS_CXX_FLAGS = Compiler flags for wxWindows, essentially " wx-config --cxxflags" on Linux WXWINDOWS_INCLUDE_DIR = where to find "wx/wx.h" and "wx/setup.h" WXWINDOWS_LINK_DIRECTORIES = link directories, useful for rpath on Unix WXWINDOWS_DEFINITIONS = extra defines

OPTIONS If you need OpenGL support please

set(WXWINDOWS_USE_GL 1)

in your CMakeLists.txt *before* you include this file.

HAVE_ISYSTEM - true required to replace -I by -isystem on g++

For convenience include Use_wxWindows.cmake in your projects CMakeLists.txt using include(${CMAKE_CUR- RENT_LIST_DIR}/Use_wxWindows.cmake).

USAGE

set(WXWINDOWS_USE_GL 1) find_package(wxWindows)

NOTES wxWidgets 2.6.x is supported for monolithic builds e.g. compiled in wx/build/msw dir as:

nmake -f makefile.vc BUILD=debug SHARED=0 USE_OPENGL=1 MONOLITHIC=1

FortranCInterface Fortran/C Interface Detection

This module automatically detects the API by which C and Fortran languages interact. Variables indicate if the mangling is found:

FortranCInterface_GLOBAL_FOUND = Global subroutines and functions FortranCInterface_MODULE_FOUND = Module subroutines and functions (declared by "MODULE PROCEDURE")

A function is provided to generate a C header file containing macros to mangle symbol names:

FortranCInterface_HEADER(<file> [MACRO_NAMESPACE <macro-ns>] [SYMBOL_NAMESPACE <ns>] [SYMBOLS [<module>:]<function> ...])

It generates in <file> definitions of the following macros:

#define FortranCInterface_GLOBAL (name,NAME) ... #define FortranCInterface_GLOBAL_(name,NAME) ... #define FortranCInterface_MODULE (mod,name, MOD,NAME) ... #define FortranCInterface_MODULE_(mod,name, MOD,NAME) ...

These macros mangle four categories of Fortran symbols, respec- tively:

- Global symbols without _: call mysub() - Global symbols with _ : call my_sub() - Module symbols without _ : use mymod; call mysub() - Module symbols with _ : use mymod; call my_sub()

If mangling for a category is not known, its macro is left unde- fined. All macros require raw names in both lower case and upper case. The MACRO_NAMESPACE option replaces the default "FortranC- Interface_" prefix with a given namespace "<macro-ns>".

The SYMBOLS option lists symbols to mangle automatically with C preprocessor definitions:

<function> ==> #define <ns><function> ... <module>:<function> ==> #define <ns><module>_<function> ...

If the mangling for some symbol is not known then no preproces- sor definition is created, and a warning is displayed. The SYM- BOL_NAMESPACE option prefixes all preprocessor definitions gen- erated by the SYMBOLS option with a given namespace "<ns>".

Example usage:

include(FortranCInterface) FortranCInterface_HEADER(FC.h MACRO_NAMESPACE "FC_")

This creates a "FC.h" header that defines mangling macros FC_GLOBAL(), FC_GLOBAL_(), FC_MODULE(), and FC_MODULE_().

Example usage:

include(FortranCInterface) FortranCInterface_HEADER(FCMangle.h MACRO_NAMESPACE "FC_" SYMBOL_NAMESPACE "FC_" SYMBOLS mysub mymod:my_sub)

This creates a "FCMangle.h" header that defines the same FC_*() mangling macros as the previous example plus preprocessor sym- bols FC_mysub and FC_mymod_my_sub.

Another function is provided to verify that the Fortran and C/C++ compilers work together:

FortranCInterface_VERIFY([CXX] [QUIET])

It tests whether a simple test executable using Fortran and C (and C++ when the CXX option is given) compiles and links suc- cessfully. The result is stored in the cache entry FortranCIn- terface_VERIFIED_C (or FortranCInterface_VERIFIED_CXX if CXX is given) as a boolean. If the check fails and QUIET is not given the function terminates with a FATAL_ERROR message describing the problem. The purpose of this check is to stop a build early for incompatible compiler combinations. The test is built in the Release configuration.

FortranCInterface is aware of possible GLOBAL and MODULE man- glings for many Fortran compilers, but it also provides an interface to specify new possible manglings. Set the variables

FortranCInterface_GLOBAL_SYMBOLS FortranCInterface_MODULE_SYMBOLS

before including FortranCInterface to specify manglings of the symbols "MySub", "My_Sub", "MyModule:MySub", and "My_Mod- ule:My_Sub". For example, the code:

set(FortranCInterface_GLOBAL_SYMBOLS mysub_ my_sub__ MYSUB_) # ^^^^^ ^^^^^^ ^^^^^ set(FortranCInterface_MODULE_SYMBOLS __mymodule_MOD_mysub __my_module_MOD_my_sub) # ^^^^^^^^ ^^^^^ ^^^^^^^^^ ^^^^^^ include(FortranCInterface)

tells FortranCInterface to try given GLOBAL and MODULE man- glings. (The carets point at raw symbol names for clarity in this example but are not needed.)

GNUInstallDirs Define GNU standard installation directories

Provides install directory variables as defined for GNU soft- ware:

http://www.gnu.org/prep/standards/html_node/Directory-Variables.html

Inclusion of this module defines the following variables:

CMAKE_INSTALL_<dir> - destination for files of a given type CMAKE_INSTALL_FULL_<dir> - corresponding absolute path

where <dir> is one of:

BINDIR - user executables (bin) SBINDIR - system admin executables (sbin) LIBEXECDIR - program executables (libexec) SYSCONFDIR - read-only single-machine data (etc) SHAREDSTATEDIR - modifiable architecture-independent data (com) LOCALSTATEDIR - modifiable single-machine data (var) LIBDIR - object code libraries (lib or lib64 or lib/<multiarch-tuple> on Debian) INCLUDEDIR - C header files (include) OLDINCLUDEDIR - C header files for non-gcc (/usr/include) DATAROOTDIR - read-only architecture-independent data root (share) DATADIR - read-only architecture-independent data (DATAROOTDIR) INFODIR - info documentation (DATAROOTDIR/info) LOCALEDIR - locale-dependent data (DATAROOTDIR/locale) MANDIR - man documentation (DATAROOTDIR/man) DOCDIR - documentation root (DATAROOTDIR/doc/PROJECT_NAME)

Each CMAKE_INSTALL_<dir> value may be passed to the DESTINATION options of install() commands for the corresponding file type. If the includer does not define a value the above-shown default will be used and the value will appear in the cache for editing by the user. Each CMAKE_INSTALL_FULL_<dir> value contains an absolute path constructed from the corresponding destination by prepending (if necessary) the value of CMAKE_INSTALL_PREFIX.

GenerateExportHeader Function for generation of export macros for libraries

This module provides the function GENERATE_EXPORT_HEADER() and the accompanying ADD_COMPILER_EXPORT_FLAGS() function.

The GENERATE_EXPORT_HEADER function can be used to generate a file suitable for preprocessor inclusion which contains EXPORT macros to be used in library classes.

GENERATE_EXPORT_HEADER( LIBRARY_TARGET

[BASE_NAME <base_name>] [EXPORT_MACRO_NAME <export_macro_name>] [EXPORT_FILE_NAME <export_file_name>] [DEPRECATED_MACRO_NAME <deprecated_macro_name>] [NO_EXPORT_MACRO_NAME <no_export_macro_name>] [STATIC_DEFINE <static_define>] [NO_DEPRECATED_MACRO_NAME <no_deprecated_macro_name>] [DEFINE_NO_DEPRECATED] [PREFIX_NAME <prefix_name>]

)

ADD_COMPILER_EXPORT_FLAGS( [<output_variable>] )

By default GENERATE_EXPORT_HEADER() generates macro names in a file name determined by the name of the library. The ADD_COM- PILER_EXPORT_FLAGS function adds -fvisibility=hidden to CMAKE_CXX_FLAGS if supported, and is a no-op on Windows which does not need extra compiler flags for exporting support. You may optionally pass a single argument to ADD_COM- PILER_EXPORT_FLAGS that will be populated with the required CXX_FLAGS required to enable visibility support for the com- piler/architecture in use.

This means that in the simplest case, users of these functions will be equivalent to:

add_compiler_export_flags() add_library(somelib someclass.cpp) generate_export_header(somelib) install(TARGETS somelib DESTINATION ${LIBRARY_INSTALL_DIR}) install(FILES someclass.h ${PROJECT_BINARY_DIR}/somelib_export.h DESTINATION ${INCLUDE_INSTALL_DIR} )

And in the ABI header files:

#include "somelib_export.h" class SOMELIB_EXPORT SomeClass { ... };

The CMake fragment will generate a file in the ${CMAKE_CUR- RENT_BINARY_DIR} called somelib_export.h containing the macros SOMELIB_EXPORT, SOMELIB_NO_EXPORT, SOMELIB_DEPRECATED, SOMELIB_DEPRECATED_EXPORT and SOMELIB_DEPRECATED_NO_EXPORT. The resulting file should be installed with other headers in the library.

The BASE_NAME argument can be used to override the file name and the names used for the macros

add_library(somelib someclass.cpp) generate_export_header(somelib BASE_NAME other_name )

Generates a file called other_name_export.h containing the macros OTHER_NAME_EXPORT, OTHER_NAME_NO_EXPORT and OTHER_NAME_DEPRECATED etc.

The BASE_NAME may be overridden by specifiying other options in the function. For example:

add_library(somelib someclass.cpp) generate_export_header(somelib EXPORT_MACRO_NAME OTHER_NAME_EXPORT )

creates the macro OTHER_NAME_EXPORT instead of SOMELIB_EXPORT, but other macros and the generated file name is as default.

add_library(somelib someclass.cpp) generate_export_header(somelib DEPRECATED_MACRO_NAME KDE_DEPRECATED )

creates the macro KDE_DEPRECATED instead of SOMELIB_DEPRECATED.

If LIBRARY_TARGET is a static library, macros are defined with- out values.

If the same sources are used to create both a shared and a static library, the uppercased symbol ${BASE_NAME}_STATIC_DEFINE should be used when building the static library

add_library(shared_variant SHARED ${lib_SRCS}) add_library(static_variant ${lib_SRCS}) generate_export_header(shared_variant BASE_NAME libshared_and_static) set_target_properties(static_variant PROPERTIES COMPILE_FLAGS -DLIBSHARED_AND_STATIC_STATIC_DEFINE)

This will cause the export macros to expand to nothing when building the static library.

If DEFINE_NO_DEPRECATED is specified, then a macro ${BASE_NAME}_NO_DEPRECATED will be defined This macro can be used to remove deprecated code from preprocessor output.

option(EXCLUDE_DEPRECATED "Exclude deprecated parts of the library" FALSE) if (EXCLUDE_DEPRECATED) set(NO_BUILD_DEPRECATED DEFINE_NO_DEPRECATED) endif() generate_export_header(somelib ${NO_BUILD_DEPRECATED})

And then in somelib:

class SOMELIB_EXPORT SomeClass { public: #ifndef SOMELIB_NO_DEPRECATED SOMELIB_DEPRECATED void oldMethod(); #endif };

#ifndef SOMELIB_NO_DEPRECATED void SomeClass::oldMethod() { } #endif

If PREFIX_NAME is specified, the argument will be used as a pre- fix to all generated macros.

For example:

generate_export_header(somelib PREFIX_NAME VTK_)

Generates the macros VTK_SOMELIB_EXPORT etc.

GetPrerequisites Functions to analyze and list executable file prerequisites.

This module provides functions to list the .dll, .dylib or .so files that an executable or shared library file depends on. (Its prerequisites.)

It uses various tools to obtain the list of required shared library files:

dumpbin (Windows) objdump (MinGW on Windows) ldd (Linux/Unix) otool (Mac OSX)

The following functions are provided by this module:

get_prerequisites list_prerequisites list_prerequisites_by_glob gp_append_unique is_file_executable gp_item_default_embedded_path (projects can override with gp_item_default_embedded_path_override) gp_resolve_item (projects can override with gp_resolve_item_override) gp_resolved_file_type (projects can override with gp_resolved_file_type_override) gp_file_type

Requires CMake 2.6 or greater because it uses function, break, return and PARENT_SCOPE.

GET_PREREQUISITES(<target> <prerequisites_var> <exclude_system> <recurse> <exepath> <dirs>)

Get the list of shared library files required by <target>. The list in the variable named <prerequisites_var> should be empty on first entry to this function. On exit, <prerequisites_var> will contain the list of required shared library files.

<target> is the full path to an executable file. <prerequi- sites_var> is the name of a CMake variable to contain the results. <exclude_system> must be 0 or 1 indicating whether to include or exclude "system" prerequisites. If <recurse> is set to 1 all prerequisites will be found recursively, if set to 0 only direct prerequisites are listed. <exepath> is the path to the top level executable used for @executable_path replacment on the Mac. <dirs> is a list of paths where libraries might be found: these paths are searched first when a target without any path info is given. Then standard system locations are also searched: PATH, Framework locations, /usr/lib...

LIST_PREREQUISITES(<target> [<recurse> [<exclude_system> [<verbose>]]])

Print a message listing the prerequisites of <target>.

<target> is the name of a shared library or executable target or the full path to a shared library or executable file. If <recurse> is set to 1 all prerequisites will be found recur- sively, if set to 0 only direct prerequisites are listed. <exclude_system> must be 0 or 1 indicating whether to include or exclude "system" prerequisites. With <verbose> set to 0 only the full path names of the prerequisites are printed, set to 1 extra informatin will be displayed.

LIST_PREREQUISITES_BY_GLOB(<glob_arg> <glob_exp>)

Print the prerequisites of shared library and executable files matching a globbing pattern. <glob_arg> is GLOB or GLOB_RECURSE and <glob_exp> is a globbing expression used with "file(GLOB" or "file(GLOB_RECURSE" to retrieve a list of matching files. If a matching file is executable, its prerequisites are listed.

Any additional (optional) arguments provided are passed along as the optional arguments to the list_prerequisites calls.

GP_APPEND_UNIQUE(<list_var> <value>)

Append <value> to the list variable <list_var> only if the value is not already in the list.

IS_FILE_EXECUTABLE(<file> <result_var>)

Return 1 in <result_var> if <file> is a binary executable, 0 otherwise.

GP_ITEM_DEFAULT_EMBEDDED_PATH(<item> <default_embedded_path_var>)

Return the path that others should refer to the item by when the item is embedded inside a bundle.

Override on a per-project basis by providing a project-specific gp_item_default_embedded_path_override function.

GP_RESOLVE_ITEM(<context> <item> <exepath> <dirs> <resolved_item_var>)

Resolve an item into an existing full path file.

Override on a per-project basis by providing a project-specific gp_resolve_item_override function.

GP_RESOLVED_FILE_TYPE(<original_file> <file> <exepath> <dirs> <type_var>)

Return the type of <file> with respect to <original_file>. String describing type of prerequisite is returned in variable named <type_var>.

Use <exepath> and <dirs> if necessary to resolve non-absolute <file> values -- but only for non-embedded items.

Possible types are:

system local embedded other

Override on a per-project basis by providing a project-specific gp_resolved_file_type_override function.

GP_FILE_TYPE(<original_file> <file> <type_var>)

Return the type of <file> with respect to <original_file>. String describing type of prerequisite is returned in variable named <type_var>.

Possible types are:

system local embedded other

InstallRequiredSystemLibraries

By including this file, all library files listed in the variable CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS will be installed with install(PROGRAMS ...) into bin for WIN32 and lib for non-WIN32. If CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS_SKIP is set to TRUE before including this file, then the INSTALL command is not called. The user can use the variable CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS to use a custom install command and install them however they want. If it is the MSVC compiler, then the microsoft run time libraries will be found and automatically added to the CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS, and installed. If CMAKE_INSTALL_DEBUG_LIBRARIES is set and it is the MSVC com- piler, then the debug libraries are installed when available. If CMAKE_INSTALL_DEBUG_LIBRARIES_ONLY is set then only the debug libraries are installed when both debug and release are available. If CMAKE_INSTALL_MFC_LIBRARIES is set then the MFC run time libraries are installed as well as the CRT run time libraries. If CMAKE_INSTALL_SYSTEM_RUNTIME_DESTINATION is set then the libraries are installed to that directory rather than the default. If CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS_NO_WARNINGS is NOT set, then this file warns about required files that do not exist. You can set this variable to ON before including this file to avoid the warning. For example, the Visual Studio Express editions do not include the redistributable files, so if you include this file on a machine with only VS Express installed, youll get the warning.

MacroAddFileDependencies MACRO_ADD_FILE_DEPENDENCIES(<_file> depend_files...)

Using the macro MACRO_ADD_FILE_DEPENDENCIES() is discouraged. There are usually better ways to specify the correct dependen- cies.

MACRO_ADD_FILE_DEPENDENCIES(<_file> depend_files...) is just a convenience wrapper around the OBJECT_DEPENDS source file prop- erty. You can just use set_property(SOURCE <file> APPEND PROP- ERTY OBJECT_DEPENDS depend_files) instead.

ProcessorCount ProcessorCount(var)

Determine the number of processors/cores and save value in ${var}

Sets the variable named ${var} to the number of physical cores available on the machine if the information can be determined. Otherwise it is set to 0. Currently this functionality is imple- mented for AIX, cygwin, FreeBSD, HPUX, IRIX, Linux, Mac OS X, QNX, Sun and Windows.

This function is guaranteed to return a positive integer (>=1) if it succeeds. It returns 0 if theres a problem determining the processor count.

Example use, in a ctest -S dashboard script:

include(ProcessorCount) ProcessorCount(N) if(NOT N EQUAL 0) set(CTEST_BUILD_FLAGS -j${N}) set(ctest_test_args ${ctest_test_args} PARALLEL_LEVEL ${N}) endif()

This function is intended to offer an approximation of the value of the number of compute cores available on the current machine, such that you may use that value for parallel building and par- allel testing. It is meant to help utilize as much of the machine as seems reasonable. Of course, knowledge of what else might be running on the machine simultaneously should be used when deciding whether to request a machines full capacity all for yourself.

SelectLibraryConfigurations

select_library_configurations( basename )

This macro takes a library base name as an argument, and will choose good values for basename_LIBRARY, basename_LIBRARIES, basename_LIBRARY_DEBUG, and basename_LIBRARY_RELEASE depending on what has been found and set. If only base- name_LIBRARY_RELEASE is defined, basename_LIBRARY will be set to the release value, and basename_LIBRARY_DEBUG will be set to basename_LIBRARY_DEBUG-NOTFOUND. If only basename_LIBRARY_DEBUG is defined, then basename_LIBRARY will take the debug value, and basename_LIBRARY_RELEASE will be set to base- name_LIBRARY_RELEASE-NOTFOUND.

If the generator supports configuration types, then base- name_LIBRARY and basename_LIBRARIES will be set with debug and optimized flags specifying the library to be used for the given configuration. If no build type has been set or the generator in use does not support configuration types, then base- name_LIBRARY and basename_LIBRARIES will take only the release value, or the debug value if the release one is not set.

SquishTestScript

This script launches a GUI test using Squish. You should not call the script directly; instead, you should access it via the SQUISH_ADD_TEST macro that is defined in FindSquish.cmake.

This script starts the Squish server, launches the test on the client, and finally stops the squish server. If any of these steps fail (including if the tests do not pass) then a fatal error is raised.

TestBigEndian Define macro to determine endian type

Check if the system is big endian or little endian

TEST_BIG_ENDIAN(VARIABLE) VARIABLE - variable to store the result to

TestCXXAcceptsFlag Test CXX compiler for a flag

Check if the CXX compiler accepts a flag

Macro CHECK_CXX_ACCEPTS_FLAG(FLAGS VARIABLE) - checks if the function exists FLAGS - the flags to try VARIABLE - variable to store the result

TestForANSIForScope Check for ANSI for scope support

Check if the compiler restricts the scope of variables declared in a for-init-statement to the loop body.

CMAKE_NO_ANSI_FOR_SCOPE - holds result

TestForANSIStreamHeaders Test for compiler support of ANSI stream headers iostream, etc.

check if the compiler supports the standard ANSI iostream header (without the .h)

CMAKE_NO_ANSI_STREAM_HEADERS - defined by the results

TestForSSTREAM Test for compiler support of ANSI sstream header

check if the compiler supports the standard ANSI sstream header

CMAKE_NO_ANSI_STRING_STREAM - defined by the results

TestForSTDNamespace Test for std:: namespace support

check if the compiler supports std:: on stl classes

CMAKE_NO_STD_NAMESPACE - defined by the results

UseEcos This module defines variables and macros required to build eCos application.

This file contains the following macros: ECOS_ADD_INCLUDE_DIREC- TORIES() - add the eCos include dirs ECOS_ADD_EXECUTABLE(name source1 ... sourceN ) - create an eCos executable ECOS_ADJUST_DIRECTORY(VAR source1 ... sourceN ) - adjusts the path of the source files and puts the result into VAR

Macros for selecting the toolchain: ECOS_USE_ARM_ELF_TOOLS() - enable the ARM ELF toolchain for the directory where it is called ECOS_USE_I386_ELF_TOOLS() - enable the i386 ELF toolchain for the directory where it is called ECOS_USE_PPC_EABI_TOOLS() - enable the PowerPC toolchain for the directory where it is called

It contains the following variables: ECOS_DEFINITIONS ECOSCON- FIG_EXECUTABLE ECOS_CONFIG_FILE - defaults to ecos.ecc, if your eCos configuration file has a different name, adjust this variable for internal use only:

ECOS_ADD_TARGET_LIB

UseJava Use Module for Java

This file provides functions for Java. It is assumed that Find- Java.cmake has already been loaded. See FindJava.cmake for information on how to load Java into your CMake project.

add_jar(target_name

[SOURCES] source1 [source2 ...] [resource1 ...] [INCLUDE_JARS jar1 [jar2 ...]] [ENTRY_POINT entry] [VERSION version] [OUTPUT_NAME name] [OUTPUT_DIR dir] )

This command creates a <target_name>.jar. It compiles the given source files (source) and adds the given resource files (resource) to the jar file. If only resource files are given then just a jar file is created. The list of include jars are added to the classpath when compiling the java sources and also to the dependencies of the target. INCLUDE_JARS also accepts other target names created by add_jar. For backwards compatibil- ity, jar files listed as sources are ignored (as they have been since the first version of this module).

The default OUTPUT_DIR can also be changed by setting the vari- able CMAKE_JAVA_TARGET_OUTPUT_DIR.

Additional instructions:

To add compile flags to the target you can set these flags with the following variable:

set(CMAKE_JAVA_COMPILE_FLAGS -nowarn)

To add a path or a jar file to the class path you can do this with the CMAKE_JAVA_INCLUDE_PATH variable.

set(CMAKE_JAVA_INCLUDE_PATH /usr/share/java/shibboleet.jar)

To use a different output name for the target you can set it with:

add_jar(foobar foobar.java OUTPUT_NAME shibboleet.jar)

To use a different output directory than CMAKE_CURRENT_BINARY_DIR you can set it with:

add_jar(foobar foobar.java OUTPUT_DIR ${PROJECT_BINARY_DIR}/bin)

To define an entry point in your jar you can set it with the ENTRY_POINT named argument:

add_jar(example ENTRY_POINT com/examples/MyProject/Main)

To add a VERSION to the target output name you can set it using the VERSION named argument to add_jar. This will create a jar file with the name shibboleet-1.0.0.jar and will create a symlink shibboleet.jar pointing to the jar with the version information.

add_jar(shibboleet shibbotleet.java VERSION 1.2.0)

If the target is a JNI library, utilize the following commands to create a JNI symbolic link:

set(CMAKE_JNI_TARGET TRUE) add_jar(shibboleet shibbotleet.java VERSION 1.2.0) install_jar(shibboleet ${LIB_INSTALL_DIR}/shibboleet) install_jni_symlink(shibboleet ${JAVA_LIB_INSTALL_DIR})

If a single target needs to produce more than one jar from its java source code, to prevent the accumulation of duplicate class files in subsequent jars, set/reset CMAKE_JAR_CLASSES_PREFIX prior to calling the add_jar() function:

set(CMAKE_JAR_CLASSES_PREFIX com/redhat/foo) add_jar(foo foo.java)

set(CMAKE_JAR_CLASSES_PREFIX com/redhat/bar) add_jar(bar bar.java)

Target Properties:

The add_jar() functions sets some target properties. You can get these properties with the get_property(TARGET <target_name> PROPERTY <propery_name>) command.

INSTALL_FILES The files which should be installed. This is used by install_jar(). JNI_SYMLINK The JNI symlink which should be installed. This is used by install_jni_symlink(). JAR_FILE The location of the jar file so that you can include it. CLASS_DIR The directory where the class files can be found. For example to use them with javah.

find_jar(<VAR>

name | NAMES name1 [name2 ...] [PATHS path1 [path2 ... ENV var]] [VERSIONS version1 [version2]] [DOC "cache documentation string"] )

This command is used to find a full path to the named jar. A cache entry named by <VAR> is created to stor the result of this command. If the full path to a jar is found the result is stored in the variable and the search will not repeated unless the variable is cleared. If nothing is found, the result will be <VAR>-NOTFOUND, and the search will be attempted again next time find_jar is invoked with the same variable. The name of the full path to a file that is searched for is specified by the names listed after NAMES argument. Additional search locations can be specified after the PATHS argument. If you require special a version of a jar file you can specify it with the VERSIONS argu- ment. The argument after DOC will be used for the documentation string in the cache.

install_jar(TARGET_NAME DESTINATION)

This command installs the TARGET_NAME files to the given DESTI- NATION. It should be called in the same scope as add_jar() or it will fail.

install_jni_symlink(TARGET_NAME DESTINATION)

This command installs the TARGET_NAME JNI symlinks to the given DESTINATION. It should be called in the same scope as add_jar() or it will fail.

create_javadoc(<VAR>

PACKAGES pkg1 [pkg2 ...] [SOURCEPATH <sourcepath>] [CLASSPATH <classpath>] [INSTALLPATH <install path>] [DOCTITLE "the documentation title"] [WINDOWTITLE "the title of the document"] [AUTHOR TRUE|FALSE] [USE TRUE|FALSE] [VERSION TRUE|FALSE] )

Create java documentation based on files or packages. For more details please read the javadoc manpage.

There are two main signatures for create_javadoc. The first sig- nature works with package names on a path with source files:

Example: create_javadoc(my_example_doc PACKAGES com.exmaple.foo com.example.bar SOURCEPATH "${CMAKE_CURRENT_SOURCE_DIR}" CLASSPATH ${CMAKE_JAVA_INCLUDE_PATH} WINDOWTITLE "My example" DOCTITLE "<h1>My example</h1>" AUTHOR TRUE USE TRUE VERSION TRUE )

The second signature for create_javadoc works on a given list of files.

create_javadoc(<VAR> FILES file1 [file2 ...] [CLASSPATH <classpath>] [INSTALLPATH <install path>] [DOCTITLE "the documentation title"] [WINDOWTITLE "the title of the document"] [AUTHOR TRUE|FALSE] [USE TRUE|FALSE] [VERSION TRUE|FALSE] )

Example:

create_javadoc(my_example_doc FILES ${example_SRCS} CLASSPATH ${CMAKE_JAVA_INCLUDE_PATH} WINDOWTITLE "My example" DOCTITLE "<h1>My example</h1>" AUTHOR TRUE USE TRUE VERSION TRUE )

Both signatures share most of the options. These options are the same as what you can find in the javadoc manpage. Please look at the manpage for CLASSPATH, DOCTITLE, WINDOWTITLE, AUTHOR, USE and VERSION.

The documentation will be by default installed to

${CMAKE_INSTALL_PREFIX}/share/javadoc/<VAR>

if you dont set the INSTALLPATH.

UseJavaClassFilelist

This script create a list of compiled Java class files to be added to a jar file. This avoids including cmake files which get created in the binary directory.

UseJavaSymlinks

Helper script for UseJava.cmake

UsePkgConfig Obsolete pkg-config module for CMake, use FindPkgConfig instead.

This module defines the following macro:

PKGCONFIG(package includedir libdir linkflags cflags)

Calling PKGCONFIG will fill the desired information into the 4 given arguments, e.g. PKGCONFIG(libart-2.0 LIBART_INCLUDE_DIR LIBART_LINK_DIR LIBART_LINK_FLAGS LIBART_CFLAGS) if pkg-config was NOT found or the specified software package doesnt exist, the variable will be empty when the function returns, otherwise they will contain the respective information

UseQt4 Use Module for QT4

Sets up C and C++ to use Qt 4. It is assumed that FindQt.cmake has already been loaded. See FindQt.cmake for information on how to load Qt 4 into your CMake project.

UseSWIG SWIG module for CMake

Defines the following macros:

SWIG_ADD_MODULE(name language [ files ]) - Define swig module with given name and specified language SWIG_LINK_LIBRARIES(name [ libraries ]) - Link libraries to swig module

All other macros are for internal use only. To get the actual name of the swig module, use: ${SWIG_MODULE_${name}_REAL_NAME}. Set Source files properties such as CPLUSPLUS and SWIG_FLAGS to specify special behavior of SWIG. Also global CMAKE_SWIG_FLAGS can be used to add special flags to all swig calls. Another spe- cial variable is CMAKE_SWIG_OUTDIR, it allows one to specify where to write all the swig generated module (swig -outdir option) The name-specific variable SWIG_MODULE_<name>_EXTRA_DEPS may be used to specify extra dependencies for the generated mod- ules. If the source file generated by swig need some special flag you can use set_source_files_properties( ${swig_gener- ated_file_fullname}

PROPERTIES COMPILE_FLAGS "-bla")

Use_wxWindows ---------------------------------------------------

This convenience include finds if wxWindows is installed and set the appropriate libs, incdirs, flags etc. author Jan Woetzel <jw -at- mip.informatik.uni-kiel.de> (07/2003) USAGE:

just include Use_wxWindows.cmake in your projects CMakeLists.txt

include( ${CMAKE_MODULE_PATH}/Use_wxWindows.cmake)

if you are sure you need GL then

set(WXWINDOWS_USE_GL 1)

*before* you include this file.

UsewxWidgets Convenience include for using wxWidgets library.

Determines if wxWidgets was FOUND and sets the appropriate libs, incdirs, flags, etc. INCLUDE_DIRECTORIES and LINK_DIRECTORIES are called.

USAGE

# Note that for MinGW users the order of libs is important! find_package(wxWidgets REQUIRED net gl core base) include(${wxWidgets_USE_FILE}) # and for each of your dependent executable/library targets: target_link_libraries(<YourTarget> ${wxWidgets_LIBRARIES})

DEPRECATED

LINK_LIBRARIES is not called in favor of adding dependencies per target.
