How to use

1. Check out the repo
2. Update commit-hash to point to the right dxc commit hash
3. Download the build artifacts
4. Unzip all artifacts into the right directories in breda (crates/breda-shader-compiler/dxc/<triple>/)
5. When on macOS, issue xattr -d com.apple.quarantine libdxcompiler.dylib to de-quarantine the library (your browser will quarantine executable files, we'll need to tell macOS)
