Details: - New options to control building projectM as either static, shared or both libraries. - The reference UIs can now also be linked to the shared library if it is built. - Added an option to disable building the SDL frontend. SDL2 is still required for tests and the Emscripten build. - Initial option for building Doxygen documentation, but the feature is currently not implemented beyond that. - The SDL frontend no longer derives from the projectM class, but uses the C-based API calls instead.
