CUDA_CUDA_LIBRARY Error Cmake

[bretwitt]

Host system has NVIDIA Container Toolkit 15.2, CUDA 11.4 on Ubuntu 20.04 (if it matters)

I'm building with atk dev -ba -s chrono --optionals gpus vnc to build a fresh Chrono image (the dockerhub one is out of date for the current Chrono feature/ros branch) I'm also building for humble

I'm running into the following error at step 13

Would appreciate some guidance!

As an update, error is reproduced with CUDA 12.2 and NVIDIA CUDA toolkit 12.2 and nvidia_container_toolkit

This was fixed by appending -DCMAKE_LIBRARY_PATH=/usr/local/cuda/lib64/stubs to the CMake build command. The demo_ART_cone.py needed some small fixes to accomodate a (new?) PyChrono API. I'd be happy to make it a PR/fork if needed

@bretwitt Ah sorry, I must have notifcations disabled! Thanks for the update. Odd that it worked okay before and not anymore. Looks like we can just set -DCMAKE_LIBRARY_PATH=${LIBRARY_PATH} since nvidia includes the cuda library path in the LIBRARY_PATH env variable (I wonder if there was a change in chrono which caused this to break, probably okay to do this for now tho). I will make a PR with this change, as well as updating the chrono branch to main since feature/ros has been merged in the latest release.

As for the PyChrono demo fixes, feel free to make a PR with those! I meant to update those, but didn't get to it. Thanks for debugging that!!
