Headers only INTERFACE library with generated headers don't work in CMake because the GENERATED property is local to a directory. Instead we make a STATIC library with a Dummy cpp file. INTERFACE libraries can only have INTERFACE sources so the sources get added to the dependant's list of sources. If these dependents are in another directory, they don't see the GENERATED property and fail to configure because the file doesn't exist on disk. Use this trick for both dawn_headers and dawncpp_headers that are header only libraries with generated headers.

Dawn, a WebGPU implementation
Dawn is an open-source and cross-platform implementation of the work-in-progress WebGPU standard.
More precisely it implements webgpu.h that is a one-to-one mapping with the WebGPU IDL.
Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.
Dawn provides several WebGPU building blocks:
- WebGPU C/C++ headers that applications and other building blocks use.
- The
webgpu.hversion that Dawn implements. - A C++ wrapper for the
webgpu.h.
- The
- A "native" implementation of WebGPU using platforms' GPU APIs:
- D3D12 on Windows 10
- Metal on macOS and iOS
- Vulkan on Windows, Linux, ChromeOS, Android and Fuchsia
- OpenGL as best effort where available
- A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
