Description

SetupCxxFlags.cmake does not list "RELWITHDEBINFO" in the final flag setup, so cmake will error out if that build config is selected. It's handy for quick debugging without switching your python build etc over to "DEBUG".

FindClangTools.cmake could check the version of 'clang-format' (no version suffix) to see if it satisfies a version requirement.
