No CUDA runtime is found, using CUDA_HOME='/usr/lib/cuda'

Hello, not sure if some of you has had the same problem while installing the code.

When I try to run: bash scripts/install_ext.sh or pip install ./raymarching

I get the error: No CUDA runtime is found, using CUDA_HOME='/usr/lib/cuda'

I have Ubuntu 22 jammy jellyfish, pytorch 1.13 and cuda 1.15.
