Confused about dependencies in build instructions. about mpv-build

[CounterPillow]

mpv-build includes libass, libplacebo and ffmpeg. Any dependency beyond that is up to you to install. You can see what is used on e.g. Debian here: https://github.com/mpv-player/mpv-build/blob/master/debian/control#L6

@CounterPillow I see, thanks. Would you be able to help me run down a build problem? I installed all the packages from that link, and I also did apt-get build-dep mpv, but it's building without GLSL:

Install glslang-dev. If it still doesn't work, then your distro's glslang is too old.

User was just missing glslang as noted.
