Setup the udev rules for the ZED cameras

	# This script will setup USB rules to open the ZED cameras without root access
	# This can also be useful to access the cameras from a docker container without root (this script needs to be run on the host)
	# NB: Running the ZED SDK installer will already setup those

	# Print the commands
	set -x
	# Download the lightest installer
	wget -q https://download.stereolabs.com/zedsdk/3.5/jp44/jetsons -O zed_installer.run
	# Extracting only the file we're interested in
	bash ./zed_installer.run --tar -x './99-slabs.rules' > /dev/null 2>&1
