Treat compiler warnings as errors

Treat them as errors globally. Most of the time a warning is a bug, or problem in code that could be solved in a different (better) manner. Thirdparty code have this disabled. The warnings as errors option can be globally disabled through the CMake GUI, but this is not recommended.
