I'd prefer to see an approach that abstracts the warning levels
in a similar way to COMPILE_FEATURES, COMPILE_DEFINITIONS,
INCLUDE_DIRECTORIES, etc.  Project code would set directory or
target properties to specify warning levels and the generators
would map them to the proper flags or project file settings
automatically.

Something like this has long been missing for compiler warnings
and optimization levels.
