Provide shared library (libmupdf.so) in mupdf package

[Mark-Joy]

Requesting new package

mupdf package has mostly header files with no library.
mupdf-static package provides only static libs.
Please support shared library (libmupdf.so) in mupdf.
It is needed for PyMuPDF - Python binding with support for MuPDF.

Additional information
Have you compiled or tried to compile the package on device?

• If it did work then please share build steps and any patches that you had to apply.

Try pkg upgrade to install 1.18.0-1. It should be already available on packages.termux.org and a bit later on mirrors.

One issue when run mupdf-tools

λ [~] $ muraster
CANNOT LINK EXECUTABLE "muraster": library "build/shared-release/libmupdf.so" not found
λ [~] $ mutool
CANNOT LINK EXECUTABLE "mutool": library "build/shared-release/libmupdf.so" not found

Possible fix is to copy latest Makefile and Makerules from: https://github.com/ArtifexSoftware/mupdf

Reference: Don't hardwire path to $OUT in when linking against shared library.

This should be fixed in next update by ed992bc.

Somehow mupdf-static package was removed.
PyMuPDF needs libmupdf-third.a to compile, which is part of mupdf-static
Could both mupdf (shared lib) package and mupdf-static package be supported on Termux?

Could both mupdf (shared lib) package and mupdf-static package be supported on Termux?

Building additional libraries in termux_step_post_install may just satisfy this requirement, here's a code snippet.
