How to properly static link webgpu_dawn in my project?

[Arias Han]

Hi All,

I found that  dawn's cmake only has a shared version(webgpu_dawn). So how should I connect my program to the static version of webgpu_dawn? 

Best regards,

Arias

This reply is probably too late but I'm sharing my solution here. There are some hacks abusing internal build settings and it would be great if someone can share a better way.
