mupdf-1.18.0

[Bruce Dubbs]

New minor version.

Now the patch can't be applied, and USE_SYSTEM_LIBS breaks the build.

My build is done by:

1. apply a patch

diff --color -Naur mupdf-1.18.0-source/Makefile mupdf-1.18.0-source-fixed/Makefile
--- mupdf-1.18.0-source/Makefile	2020-10-07 18:35:03.000000000 +0800

 THIRD_LIB = $(OUT)/libmupdf-third.a

2. build with

make shared=yes USE_SYSTEM_{HARFBUZZ,LIBJPEG,OPENJPEG,ZLIB,GLUT,CURL}=yes

It would only produce one shared library (libmupdf.so), which contains the content of all libmupdf*.a archives.

Fixed at revision 23805.

This was very challenging. Upstream obviously never tested building and running using shared libraries. I had to hack the Makefile to get it to work with the shared libmupdf.so library. I'll note that both Fedora and Arch do not uses the shared libraries.
