Installing rtabmap on ROS2

[ryleymcc]

Im trying to get rtabmap on ROS2 foxy. following this https://github.com/IntelRealSense/realsense-ros/tree/foxy when i run rosdep install -i --from-path src --rosdistro $ROS_DISTRO -y i get the error

ERROR: the following packages/stacks could not have their rosdep keys resolved to system dependencies: rtabmap_ros: Cannot locate rosdep definition for [find_object_2d]

I don't think its causing me issues yet but just thought i should document this to help ROS2 mature.

I don't think this library is available on ros-2.

Humm, make sure you are on ros2 branch of rtabmap_ros: https://github.com/introlab/rtabmap_ros/blob/ros2/package.xml (find_object_2d is not a dependency). Find-Object is indeed not released on ROS2. If there is an interest, I could check to port it.
