DensifyPointCloud: error while loading shared libraries: libcuda.so.1

What is the problem?

DensifyPointCloud: error while loading shared libraries: libcuda.so.1

What should be the expected behavior?

libcuda.so.1 should be found in the docker image.

Looks like the expected path is missing in the image. Adding this path corrects the issue.

mkdir /usr/local/nvidia
ln -s /usr/local/cuda-11.2/compat /usr/local/nvidia/lib
ls -l /usr/local/nvidia/lib/

How can we reproduce this? (What steps did you do to trigger the problem? Be detailed)

This may be from a poorly formed LD_LIBRARY_PATH variable in the container.
