Patch for libxml2 (WIP)


I've been hacking on libxml2 a bit including converting it to CMake and would like some input, there are some differences between current version and the new version that I'm not sure about on how to handle.

 -- CMAKE --
prefix is expanded
XML2_LIBS="-lxml2 -lz -llzma -pthread   -lm"

 -- Autotools --
XML2_LIBS="-lxml2 -lz  -L/usr/lib -llzma  -L/usr/lib  -lm"

 -- CMAKE --
Libs.private:  -pthread -lz -llzma  -lm

 -- Autotools --
Libs.private:  -lz  -L/usr/lib -llzma -L/usr/lib -lm

Is -L/usr/lib needed? From what I can tell CMake doesn't have a variable for this, suggestions are welcome. In worst case we can hardcode it.

Current version in ports forces -DPIC cflag, is this needed?

make test passes on 13-STABLE (amd64)

Motivation for moving to CMake is mainly because it's faster and much easier to debug, I do plan to upstream as many changes as possible but perhaps it's futile effort?

I'm not sure how to handle py-libxml2 in a sane way. :/

Note for users:

Changes for 2.9.12

Thanks in advance,

I think it is generally a good idea to move the ports to use a more modern build system.

Also the -L/usr/lib should be there by default anyways, so, no loss there.

What's the issue you're having with the python variant?

Thanks for the reply! I'll drop that and ${CMAKE_INSTALL_OLDINCLUDEDIR}.

The issue with the python port is that it currently works as it's own project ( https://github.com/freebsd/freebsd-ports/blob/main/textproc/py-libxml2/Makefile#L10 ) unless I've misunderstood how it works. This approach isn't possible with at least the current upstream version of CMakeLists.txt and I'm not sure how to handle it properly being a python port.

Best regards,

Patch for libxml2 (WIP) v2

Clean up Makefile a bit more, remove CMAKE_INSTALL_OLDINCLUDEDIR
Still not sure how to handle py-libxml2
There are a few patches left that wont be needed depending on how we end up doing python port.

I don't have time/ability to hack on this within a reasonable timeframe so just stick to autotools for now.
