How do I access SDL3_mixer/SDL_mixer.h when using SDL3?

[lailoken]

When building against SDL3, I don't see the corresponding SDL3_mixer/SDL_mixer.h

How do I get this working? I tried adding -sUSE_SDL_MIXER=3 but that did not seem to help.

I was not able to use SDL2's mixer with SDL3 since that caused some typename conflicts and other errors.

We don't have SDL3 mixer ported to and an emscripten port yet.

It should be fairly easy to add if you would like to.

See #24601 and #24634
