Here is some CMake code that I wrote to determine this:

CHECK_CXX_SOURCE_COMPILES(

int main() {

#else
THIS IS NOT THE SUN

This is already done in CMake 2.6. See Modules/CMakeCCompilerId.c.in,
it is even better than the above because it works when cross compiling.
It does not use a try-run, but rather a try-compile, and then it looks
for strings in the executable that was created.
Anyway, it is already done, and it sets the following variables:
CMAKE_C_COMPILER_ID
CMAKE_CXX_COMPILER_ID
CMAKE_Fortran_COMPILER_ID
