Paths inside a toolchain file, the more appropriate variable to use would beĬMAKE_CURRENT_LIST_DIR, since it always has an unambiguous, In most cases, where there is a need to evaluate Have different values when used in different places (e.g. The toolchain file is used in contexts where these variables Set to true when CMake is cross-compiling.ĬMAKE_BINARY_DIR variables inside a toolchain file is typically DCMAKE_TOOLCHAIN_FILE=path/to/file, the file will be loaded early to If cmake(1) is invoked with the command line parameter Target properties add flags for hidden visibility, if supported by the _VISIBILITY_PRESET and VISIBILITY_INLINES_HIDDEN For example, POSITION_INDEPENDENT_CODEĪllows specifying that a target should be built as position-independentĬode, if the compiler supports that feature. Some toolchain features have built-in handling in CMake, and do 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 Such as CheckSourceCompiles, CheckCXXSymbolExists andĬheckIncludeFile to test capability and availability of various TOOLCHAIN FEATURESĬMake provides the try_compile() command and wrapper macros Overridden with the LINKER_LANGUAGE target property.
