Building on Alpine Linux

[tabletseeker]

Hello I created this dockerfile that builds mpv with on debian, but even when cleaned up the size is still > 480MB.
https://github.com/tabletseeker/mpv_build_custom/tree/master

This is the build script used in container (for debian)
https://github.com/tabletseeker/mpv_build_custom/blob/master/mpv-common.sh

I would like to build on alpine linux instead, but apparently there are some caveats because of musl.

Is there another way to generate build dependencies similar tomk-build-deps?
