Ryan,
It's very good to know.

I've seen, great!

I'm having access to CMake 2.8.0 at this moment
And, this version sets CMAKE_CXX_COMPILER_ID to GNU, even if
C/C++ compilers set to clang:
cmake -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++
Also, simple test always reports the "gnu".
if("${CMAKE_CXX_COMPILER_ID}" MATCHES "clang")
message(STATUS "clang")
elseif("${CMAKE_CXX_COMPILER_ID}" MATCHES "GNU")
message(STATUS "gnu")
endif()
I will try 2.8.2 soon.
Thanks for your help!
Best regards,
