Rename the CMake script at
`${CMAKE_ROOT}\Modules\CMakeDetermineCompileFeatures.cmake` to
`${CMAKE_ROOT}\Modules\CMakeDetermineCompilerSupport.cmake`. Also,
rename the function defined in that script from
`cmake_determine_compile_features()` to
`cmake_determine_compiler_support()`.
Modify existing CMake scripts which were including the previous
CMake script to refer to the new file and call the new function.
