Milkytracker can't find submodules when building with MSYS2 UCRT64

[TheRektafire]

Hi, so I'm on Windows 11 and trying to build milkytracker with msys2 ucrt64. I cloned the repository with --recursive so it should have all the submodules, and indeed git says it downloaded and checked them out and I cans see them in src/submodules and .git/modules. But CMake can't find them and just gives me the following errors:

$ cmake -DSCALE_NEAREST=1 ..

Might it have something to do with the error about the "OLD behavior"? I do have ZLib and zzplib installed but not lhasa since I couldn't find a package for that. But I assume it should be using the submodule one anyway since that's what it's there for? It could find my installed zzplib but the path looks weird. Has anyone else tried building Milkytracker with MSYS2 and if you got it to work what did you need to do?

Slight update: as per #393 commenting out line 167 allowed me to finish the configuration step but it still couldn't find zlib or the lhasa from the repo. I even added ZLIB_LIBRARY and ZLIB_INCLUDE_DIR as environment variables and still no luck.
