"set_property can not be used on an ALIAS target" error for dawn-6420 #16

Closed austinvhuang closed 6 months ago

austinvhuang commented 6 months ago

When I build with dawn-6420 as the GIT_TAG for FetchContent, I get this error:

CMake Error at build/_deps/webgpu-backend-dawn-src/cmake/FetchDawn.cmake:157 (set_property):
  set_property can not be used on an ALIAS target.
Call Stack (most recent call first):
  build/_deps/webgpu-backend-dawn-src/CMakeLists.txt:23 (include)

When I revert to dawn-6376, this no longer occurs

Hello! If you want to update to a newer version of Dawn, start from the current head of the dawn branch which is more up to date than what the stable version of webgpu.cmake points to (which is updated less often to reduce breaking changes).

You can see in the newer FetchDawn.cmake that the call to set_property is enclosed in a test to prevent exactly the error you're running into. ;)
