CMakePM: Detect C/C++ object extension for single source build

Browse Source 
When using CMake package manager auto-setup the CMAKE_C|
XX_OUTPUT_EXTENSION is stored in the CMake cache.

This way CMake project manager can know about the correct extension when
building a single source file.

If CMAKE_C|XX_OUTPUT_EXTENSION is not found in cache it will only use
".obj" for Clang-Cl/MSVC/MinGW toolchains.
