Don't use the program name to identify the compiler - it won't work 

reliably in cases where the compiler is name /usr/bin/cc

Use the internal variable CMAKE_<LANG>_COMPILER_ID instead, which is
finally documented (but still called internal in the docs), see
http://www.cmake.org/cmake/help/v2.8.10/cmake.html#variable:CMAKE_LANG_COMPILER_ID
