This is the version number macro for the current SDL_mixer version.
Defined in <SDL_mixer.h>
#define SDL_MIXER_COMPILEDVERSION \
SDL_VERSIONNUM(SDL_MIXER_MAJOR_VERSION, SDL_MIXER_MINOR_VERSION, SDL_MIXER_PATCHLEVEL)
In versions higher than 2.9.0, the minor version overflows into the thousands digit: for example, 2.23.0 is encoded as 4300. This macro will not be available in SDL 3.x or SDL_mixer 3.x.
Deprecated, use SDL_MIXER_VERSION_ATLEAST or SDL_MIXER_VERSION instead.
