I believe I had tried that, but it does not work.  I believe the culprit is (in 
CMake-2.8.1 source:

CMakeDetermineCXXCompiler.cmake
141   CMAKE_DETERMINE_COMPILER_ID(CXX CXXFLAGS CMakeCXXCompilerId.cpp)

CMakeDetermineCompilerId.cmake
72   FILE(READ ${CMAKE_ROOT}/Modules/${src}.in ID_CONTENT_IN)

The use of CMAKE_ROOT in those files prevent them from being overridden.

Unfortunately, I don't use Matlab much at all anymore, so I am hesitant to take 
that responsibility.  Writing a test would not be that hard.  The Hello World 
could be could.  The pain comes about keeping a Matlab license current and the 
executable talking to their scheme.
