[CMake] Changing the compiler in CMakeLists

[Andriy Fedorov]

Hi,

I have a project which is using ITK and VTK compiled with gcc, but I 
want to buld the executable with mpiCC. mpiCC is basically a wrapper 
around gcc, which adds some paths and libraries. What I do now is I 
change the compiler manually in CMakeCCompiler.cmake and 
CMakeCXXCompiler.cmake, but I am sure this is not the right way to do 
it. I tried to set CMAKE_C_COMPILER in CMakeLists.txt, but CMake 
enforces gcc from ITK. Does anyone know how to do this right?
Thank you
