hello,
I am trying to cross compile pytorch that supports CUDA and CUDNN; I have encountered some issues, even though I am using CMAKE_CROSSCOMPLING=TRUE, it seems that I still execute some build products during the build process. The build logs are as follows. Can I get some information or help?

. This often occurs when you set both CUDA_HOME and CUDA_NVCC_EXECUTABLE
to non-standard locations, without also setting PATH to point to the
correct nvcc. Perhaps, try re-running this command again with
PATH=/cuda/jetson_lib/cuda-12.6/bin:$PATH. See above log messages for more
diagnostics, and see https://github.com/pytorch/pytorch/issues/8092 for
more details.
