We use this
if(CMAKE_C_COMPILER MATCHES "clang" OR CMAKE_CXX_COMPILER MATCHES "clang")
set(COMPILING_WITH_CLANG True)
elseif(CMAKE_C_COMPILER MATCHES ".*gcc.*" OR CMAKE_CXX_COMPILER MATCHES
".*g[+][+].*")
set(COMPILING_WITH_GCC True)
endif()

I was looking for a way to identify the compiler as clang to know if I should
pass it a clang specific flag ("-x c++").
On Darwin default compiler is Clang used through /usr/bin/cc and and
/usr/bin/c++. The identification is clearly signaled as "Clang 4.1.0" but
CMAKE_CXX_COMPILER_ID is not set
