Change Details

This change the behavior of the `add_(<LANG>_)compiler_flags` macros. Rather than editing the CFLAGS and/or CXXFLAGS, it adds the flag to the `COMPILE_OPTIONS` property of the targets in the calling directory and below that are added after this command is invoked. The final goal is to avoid changing the CFLAGS/CXXFLAGS, because they are not linked to target properties and are used in every build, including the cmake checks such as `check_cxx_source_compiles()`.
