LuisaRender (Ray Tracing): cmake build error on Windows: downloading 'https://github.com/LuisaGroup/SDKs/releases/download/sdk/dx_sdk_20240920.zip' failed - 404

[floppyinfant]

Followed the Guide to enable Ray Tracing from https://genesis-world.readthedocs.io/en/latest/user_guide/getting_started/visualization.html#photo-realistic-ray-tracing-rendering.

CMake tries to download dx_sdk_20240920.zip from https://github.com/LuisaGroup/SDKs/releases/download/sdk/, but this Version / File does not exist anymore. There are only Versions dx_sdk_20250614.zip or dx_sdk_20250816.zip.

I dont know where and how to fix the CMakeList.txt or if its even possible with the newer SDKs. Please help!
