It's not perfect, but I haven't found anything better yet.  I actually use
pkgconf https://github.com/pkgconf/pkgconf instead of pkg-config.  I also
do a lot of editing of the .pc files to make sure they're populated
properly especially if I'm building statically.  I put all my commands and
modifications in scripts similar to slackbuild scripts so they're automated
and I can replicate what I did whenever I build Free and Open Source
software.

As I mentioned, I have some libraries/headers that make up for missing
functionality on Windows to get other libraries to work.  So, most people
wouldn't be pulling in all the same headers I would.

If you're on Windows, you run msys or msys.bat to start msys and it should
work from there.

I just have a quick command line shortcut batch file with the following:
set MSYSTEM=MINGW32
start \msys\bin\sh --login -i

Just make sure the path points to where the sh.exe program is under msys on
your particular system.

Many FLOSS developers just build programs on Linux and use projects like
https://github.com/mxe/mxe to help cross-compile libraries.

I do have mingw64 around somewhere, so if you need a build tested with
that, let me know.

Will give it a try.  Will let you know if I get the patches to make sixel
graphics working.

Nice.

Will try it out.  Mainly trying to find a way to deal with svg output from
abcm2ps and other command line programs that can generate svg.

I like nanosvg much better than cairosvg or rsvg.  It's also much more
compact, just a header file.  It's been used by SDL_image and FLTK as well
because it's lightweight and has few dependencies.  It handles svg pretty
well considering how lightweight it is, but doesn't do too well with output
from abcm2ps.

Thank you so much for doing such a wonderful job with it.  If I can help
out with testing on Windows or something like that, let me know.

Thanks again.

Sincerely,
Laura
