Wouldn't it be better to check if mupdf is installed and if it is, we dynamically link, and if it isn't, we static link? I assume homebrew installs mupdf before fancy cat if fancy cat depends on mupdf? (Thanks for your contribution btw)

i thought you wanted libraries to be statically linked and use dynamic links as a last resort

I don't mind dynamic linking. I added static linking for ease of distribution, but if there is a way of checking if the user's system has the required dependencies, I don't see why we wouldn't dynamic link

I dont mind merging this for now until I find a better way of doing things, is that ok for you?

What do you think about using pkg-config to find mupdf? In case if pkg-config or mupdf doesn't exist we can use vendored dependecies

I can't think of an elegant solution to this, for now this is fine, thank you
