System Information
Operating system:Windows 11
Graphics card:RTX3050Ti

description of error
Since I was using a workflow that involved houdini but also required the cycles renderer, I successfully built cycles from
https://projects.blender.org/blender/cycles/src/branch/main/BUILDING.md
and was able to use The test file in the example folder successfully renders

But houdini does not call cycles properly with the hydra agent (picture below)

Build libraries:OPTIX SDK
CUDA12 Toolkit

I have now solved this problem

I feel very disappointed that the solution to this problem is not written in the tutorial
Just add to the path in the system variable ：

PATH=D:\ProgramProject\Builder\cycles\install

PATH=<path to cycles>/install/

The problems that needs to be solved now are：
1.cycles use OPTIX CUDA directly as a device
2.Houdini can not create cycles principle of bsdf material nodes
