Issue compiling using Burrito and Zig

Hi!

I am trying to compile this project as it is part of the Elixir Ash library.

I am compiling it using Burrito which is using Zig (Mingw)

I have tried to make my own `.h` files that link to the files inside Zig but it is a never ending rabit hole as file x links to y and y to z and so on...

This is the output I get:
```

```

Start with c_src/picosat.c and Makefile, then reproduce the shown zig cc cross-build for x86_64-windows. Investigate the missing sys/resource.h reported by the compiler and verify completion by successfully compiling the NIF for that target.
