This is taken from a FindBoost.cmake file I had laying around. Adjust
for your needs:
EXEC_PROGRAM(${CMAKE_CXX_COMPILER}
ARGS --version
OUTPUT_VARIABLE _boost_COMPILER_VERSION
)
STRING(REGEX REPLACE ".* ([0-9])\\.([0-9])\\.
[0-9] .*" "\\1\\2"
_boost_COMPILER_VERSION ${_boost_COMPILER_VERSION})
SET (_boost_COMPILER "-gcc${_boost_COMPILER_VERSION}")

Is there some CMake macro to report the version of the GCC compiler
version?
It seems these macros exist for the CL compiler, but I've not found
the matching macros for GCC.
Some warnings are produced w/ GCC 4, but the matching warning shut-
off option only exists for GCC 4 (not for GCC3).
I'd like to enable the -Wno-... option switch only for build built
with gcc 4, and do nothing with GCC 3.
Thanks,
Manu
