I have downloaded and successfully built octomap for dashing. But there are no executables or launch files I can start using ros2. I also tried installing via apt, but it's the same there. Does anyone know how I can use octomap with ros2? In ros there is octomap_mapping, but thats not available for ros2.

Or does anyone know a other 3D SLAM with Pointcloud2 that works for ros2?
