From the root of this repository, get the original WL API as a submodule
git submodule update --remote --init wl_3dsonar_driver/wl_api/
Then follow the instructions here to install it.
And build the ROS pkg as usual
colcon build --packages-select wl_3dsonar_driver
ros2 run wl_3dsonar_driver wl_3dsonar_driver_node
