cmake would not work on macOS with dawn #29

Open conversy opened 3 months ago

conversy commented 3 months ago

Hello,

I got the error below when running cmake as specified in the README.md: 

cmake -B build-dawn -DWEBGPU_BACKEND=DAWN

I found here that running this command before the cmake command would make it work:

export SDKROOT=$(xcrun --sdk macosx --show-sdk-path)

Maybe it's worth adding it in README.md?

Still, running the next command:

cmake --build build-dawn

would return immediately, building nothing... Maybe I did something wrong? It's on my mac M1, latest OS (sonoma 14.5 (23F79)) with Apple clang version 15.0.0 (clang-1500.3.9.4)

Best regards,

Stéphane

The error:
