Since libSDL.a and libSDL_mixer.a are compiled separately from this project, some hacks had been used to get the build running. However, this approach did not make proper use of target-level properties, which are encouraged according to modern CMake standards over global-level commands such as include_directories() or link_libraries(). OTOH, Win32 dependencies were being imported using link_libraries(), but they in fact are SDL dependencies, so target_link_libraries() can be used instead.
