Error in compiling in msys2
This has been an issue for about 4 months now. I have been unable to compile with msys2 due to two errors at link time i have verified the files are there. but the error is this .

The "/mingw64/lib/libgomp.dll.a" and "/mingw64/lib/libmingwthrd.a" libraries are specified without a C:/msys64/ prefix, unlike the other libraries.
If those files do exist, then it's probably this missing prefix that's the problem - and probably a bug in GCC's pkg-config record.
There are many team members successfully building with MSYS2, so this should be solvable. Our Windows CI VMs also build releases using the same steps.
What I can suggest is following https://github.com/dosbox-staging/dosbox-staging/blob/main/docs/build-windows.md#build-using-msys2 very closely.
Although CI builds with both GCC and Clang, we use Clang specifically for our releases. So I would suggest following those notes for the Clang pathway, and try using it.
Clang also had that error so I wonder if it was pkg-conf, cmake requires pkgconf so I wonder if that can be the issue
Odd I got it to compile using older build instructions but it seg faults on commit 0efd3da from Jan 1st but had to disable any mentions in meson about libslirp internally, so it doesn't compile it. It is installed though.
command
meson setup build/release-gcc -Dbuildtype=release -Db_asneeded=true --force-fallback-for=fluidsynth,mt32emu -Dtry_static_libs=fluidsynth,mt32emu,opusfile,png -Dfluidsynth:try-static-deps=true
Everything fails on my system I tested it on 2 other windows PCs that use the msys installer followed the build guide exactly fails all the time
