https://github.com/hexops/mach/issues/167
Publish binary releases of gpu-dawn for Windows
#169
Build DirectXShaderCompiler with zig build system
Land patches to gpu-dawn/build.zig required for Windows builds
Update and publish WIDL-produced Direct3D headers in a Windows SDK repo
Add Windows SDK repo to system_sdk.zig for use in mach/gpu-dawn
Merge patches to Dawn into main of our fork,
Patch Dawn to eliminate dependency on windows.ui.* headers and fix other issues building with Zig
Debug the compatibility issues with DX debug API expecting 3 params in Dawn vs. 1 according to headers (???) -> most likely due to outdated d3d12 headers.
Debug cause of segfaults that occurred when hacking in updated d3d headers (see COM calling convention issues discussed at https://github.com/ziglang/zig/issues/9998#issuecomment-997088467)
Produce up-to-date MinGW/GNU compatible Direct3D headers https://github.com/ziglang/zig/issues/9998#issuecomment-997088467

Super close to having Windows builds actually. Everything compiles, but need dxcompiler to get it to link and then we should be golden. Lots of changes to land here both in Mach and upstream in Dawn itself, though. Updated issue description.

This officially works, complete with binary releases from the CI system and cross compilation from any OS:

cd gpu-dawn/
zig build run-dawn-example -Dtarget=x86_64-windows-gnu

If you want to build from source, just add -Ddawn-from-source=true but note that you'll need a patched version of Zig temporarily until the patch lands upstream, see https://github.com/hexops/mach/issues/167

No -msvc builds, yet.
