For example, POSITION_INDEPENDENT_CODE allows Some toolchain features have built-in handling in CMake, and do not requireĬompile-tests. Result so that the test does not have to be performed again the next time These APIs test the toolchain in some way and cache the Toolchain Features ¶ĬMake provides the try_compile() command and wrapper macros such asĬheckCXXSourceCompiles, CheckCXXSymbolExists andĬheckIncludeFile to test capability and availability of various With the LINKER_LANGUAGE target property. Target, and in the case of static libraries, This is determined by the LANGUAGE property of source files of the Will be added to the compile command when compiling a file of a particularĬMake needs a way to determine which compiler to use to invoke the linker. The variables and the configuration-specific equivalents contain flags that The compiler identifier used by CMake CMAKE_COMPILER_VERSION The full path to the compiler used for CMAKE_COMPILER_ID Several variables relate to the language components of a toolchain which are The ENABLED_LANGUAGES global property contains the languages whichĪre currently enabled.

The target architecture and bitwidth, the location of corresponding utilities When a language is enabled, CMake finds a compiler for that language, andĭetermines some information, such as the vendor and version of the compiler, With information about compiler and utility paths. In cross-compiling scenarios, a toolchain file may be specified In normal builds, CMake automaticallyĭetermines the toolchain for host builds based on system introspection andĭefaults. The toolchain utilities availableĪre determined by the languages enabled.
