That's only 2 cases.  Use IF(CMAKE_COMPILER_IS_GNUCC) and IF(MSVC).  At 
least, these are available in CMake 2.3.  If you have more compilers 
than that, then the question is whether warning levels are abstractable 
across many different compilers.  Dunno myself, I've only had to worry 
about GCC and MSVC.
