I am looking into mupdf, I was already partway through updating to the newer
version but ran into lld-related problems that need figuring out (there is
the libssl-related thing you noticed too, actually that code is disabled
completely at the moment as it doesn't pass the pkg-config version check,
but if that's hacked away build fails due to libressl not having PKCS12_SAFEBAG
accessors yet).
