The corresponding CMake cache variable for the C compiler is 
CMAKE_C_COMPILER (note C not CC).

Also note if the C compiler has already been configured for a build tree 
it can not simply be changed.
Which is also why the CC environment variable has no effect on build 
trees where the C compiler is already configured.
