New comment by calibius on void-packages repository https://github.com/void-linux/void-packages/issues/29676#issuecomment-808513945 Comment: The problem is the current mupdf package doesn't provide a mupdf.pc and there's no (ocaml-)lablgl package. So you're looking at multiple packages/changes to support this one if you want to use the makefile. I've looked at it, but I'm not knowledgeable enough to do it. You can check out my fork and maybe point me in the right direction? It's kind of messy at the moment lol ...
