[CMake] setting/removing compiler flag (-g) for a single project directory

[Steven Velez]

Gotcha...  yeah target definitions are available globally, in all
directories after they are defined (source order is important).  I had
never thought of this as a global variable or constant, but I guess in a
way it is.
In that way, then I would think it is a sort of special case...  but I
suppose the experts should chime in.
