[Bug]: Importing Genesis in Docker Results in libGLU.so.1 Error

[schlagercollin]

Bug Description

It looks like importing genesis requires libGLU.so.1 which isn't available in the docker environment described in the README.

As a result, running the examples within the Docker container results in a shared library error.

Steps to Reproduce

# build / run docker as described in README
docker build -t genesis -f docker/Dockerfile docker

xhost +local:root

docker run --gpus all --rm -it \
-e DISPLAY=$DISPLAY \
-e LOCAL_USER_ID="$(id -u)" \
-v /dev/dri:/dev/dri \
-v /tmp/.X11-unix/:/tmp/.X11-unix \
-v $(pwd):/workspace \
--name genesis genesis:latest

# import genesis and/or run an example
python -c "import genesis"
python examples/smoke.py

Expected Behavior

Import and example(s) should run similar to non-Docker environment
