`stb_vorbis_open_IO` implicitly declared, compiler suggests `stb_vorbis_open_io`

[Semphriss]

At this line, I'm getting:

warning: implicit declaration of function 'stb_vorbis_open_IO'; did you mean 'stb_vorbis_open_io'?

and a corresponding linker error; is this a typo or a problem on my end?

I'm using SDL2MIXER_VENDORED=ON, if that plays.

It's a typo, thanks!
