CMAKE_CXX_KNOWN_FEATURES

List of C++ features known to this version of CMake.

The features listed in this global property may be known to be available to the C++ compiler. If the feature is available with the C++ compiler, it will be listed in the CMAKE_CXX_COMPILE_FEATURES variable.

The features listed here may be used with the target_compile_features() command. See the cmake-compile-features(7) manual for information on compile features and a list of supported compilers.
