    project: Add infrastructure for recording CXX compiler features · faeddf64
    Stephen Kelly authored
    Add a feature test using the compiler macros and the preprocessor to
    determine available features.
    Add a CMAKE_CXX_COMPILE_FEATURES variable which contains all features
    known to the loaded compiler, and a CMAKE_CXX_KNOWN_FEATURES variable
    containing all features known to CMake.  Add language standard specific
    variables for internal use to determine the standard-specific compile
    flags to use.
    This will be extended to other languages in the future.  Follow-up
    commits will add features which will be recorded by the feature test.
