* [sdl2-mixer] Update features behaviour.
- Reword feature description.
- Disable FLAC and MP3 support when libflac and mpg123 are not selected.
- Make libvorbis a dependency instead of a feature.
Unlike the FLAC/MP3 backends, the vorbis backend cannot be disabled.
* [sdl2-mixer] Remove alternative midi features.
The priority for MIDI backends is: fluidsynth > timidity > nativemidi.
- Turn off implicitely enabled timidity backend which shadows the
nativemidi backend.
- Remove nativemidi as it offers the same functionalities as fluidsynth
but is not available outside of Windows and Apple platforms. Moreover it
may give the false impression that MIDI is supported out of the box
* [sdl2-mixer] Use targets provided by dependencies.
This allows the dependencies to inform the sdl2-mixer about their usage
requirements, making it much easier to statically link the library.
* [sdl2-mixer] FluidSynth now requires pkg-config.
Since 2.3.1#1 FluidSynth's CMake config required pkg-config to find its
dependencies.
* [sdl2-mixer] UWP builds should work again.
* [sdl2-mixer] Update baseline.
* [sdl2-mixer] Add back a dummy libvorbis feature.
This is to keep compatibility with downstream users.
* [sdl2-mixer] Update version.
* [sdl2-mixer] Remove the dummy libvorbis feature.
Since vcpkg tool version 2023-02-16, this is no longer needed.
* [sdl2-mixer] Update version.
