yeah, their wiki isn't very helpful if you aren't using windows/don't want to use visual studio.
From my experience w/ MomentumMod, you can generate makefiles (for linux at least? Might work w/ msys2 or smth), and some projects converted the build system over to cmake (though I don't know if there's a pre-converted to cmake starting base).
Might be worth looking into, at least?
