Windows build broken? error: could not find native static library ggml-base, perhaps an -L flag is missing?

Not sure what's going on but for some reason getting this error on both windows native & linux->windows cross-compile builds. Is this something you're seeing too? Can't think what changed.

I'm on Windows x86_64 (AMD Ryzen 5 5600) and not getting any errors compiling this repository after a fresh git clone https://github.com/utilityai/llama-cpp-rs --recursive nor getting any at runtime, nor when adding llama-cpp-2's most recent published version (0.1.91) as a dependency to another crate and building there.

Is there something I missed trying to reproduce?

Coworker reported the same issue on Windows natively but I can't speak to their setup as I haven't had this issue. For me it happened trying to cross-compile to Windows from Linux:

rustup target add x86_64-pc-windows-gnu
RUSTC_WRAPPER= cargo build --target "x86_64-pc-windows-gnu" --verbose

I have a hunch that this has something to do with mingw builds. I believe my coworker was getting the mingw compiler as their C++ compiler for whatever reason. That would track that under mingw builds libraries would need a "lib" prefix although I couldn't quite figure out what the issue on the Windows side was. In any case, the PR strictly improves compat for Linux & should be safe (can't think of any environment it would pose a problem).
