Flac and Vorbis can't find Ogg dependency

[dsouth]

Just testing with everything set on and found:

When setting SDLMIXER_VORBIS_VORBISFILE ON cmake fails to find ogg dependcy.

CMake Error: install(EXPORT "targets" ...) includes target "FLAC" which requires target "ogg" that is not in any export set. CMake Error in SDL_mixer/external/vorbis/lib/CMakeLists.txt: export called with target "vorbis" which requires target "ogg" that is not in any export set.

Just realized it appears flac on is also causing a failure to find ogg as well?

I think this is something you should report to SDL_Mixer.

I haven't been able to build outside of your project.

The release for SDL_mixer point to SDL2 and I'm not sure how to recreate the issue beyond what I've seen here thus far...
