Yeah the mingw method on windows is a ludicrous thing to even think about, and llama.cpp still has that as the suggested option in the readme for some weird reason. Endless sourcing of paths that never works quite right. I literally couldn't get it to work when I first tried it last year.

Meanwhile Cmake is like two lines and somehow it's the backup fallback option? I don't get it. And well on linux it's literally just one line with make.

Building anything on windows without cmake is just... I don't know why anyone would use anything else. I used to spend hours wrestling with build failures, but after setting up cmake, it just works with everything.
