Help building skia/canvaskit for webgpu

[Miguel Camba]

I've been trying to try graphite but so far I wasn't able to make it work, so I wonder if there are more detailed instructions on how to do it.

I've created a custom build of canvaskit with ./compile.sh webgpu.

I've created custom builds of canvaskit in the past removing features we didn't use to make it smaller, so this was no issue.

But after I run our app I quickly get an error: TypeError: this._MakeGPUTextureSurface is not a function

This seems to be caused, at first glace, because compiling with the webgpu flag doesn't seem to enable the CK_ENABLE_WEBGPU build flag? I'm guessing here.

Am I doing something obviously wrong? I'm building from the main branch BTW.

Thanks!

We have not updated CanvasKit to support Graphite yet, although it should be possible to build Graphite with WASM and link it to the browser-provided WebGPU.

This is confusing. My understanding is that the custom build one gets when running `./compile.sh webgpu` was precisely a graphite-enable build of canvaskit.
