A combination of EXECUTE_PROCESS and 'gcc -dumpversion' is what you're 
looking for. IIRC:

EXECUTE_PROCESS( COMMAND gcc -dumpversion GCC_VERSION )

where GCC_VERSION will be the variable the result is saved in. After 
that you'll probably want to make a STRING operation (NOTEQUAL, LESS, 
GREATER and so on) with GCC_VERSION ...
