CMake: pro2cmake.py: Add basic support for examples
Examples need to be built stand-alone and as part of Qt, so they need a special CMakeLists.txt file that supports both use-cases. Add an --is-example switch to pro2cmake to make it generate these special CMakeLists.txt files. This is basic support only and is currently still missing the necessary find_package calls.
