octomap Ubuntu dependencies
I'm doing a full source build of ROS Kinetic w/ MoveIt and one of the "system" dependencies is the ROS-packaged libfcl-0.5-dev, which depends on ros-kinetic-octomap, which depends on ros-kinetic-catkin / python-catkin-pkg. I'm not super familiar with ROS packaging, so I have two questions:
1) Why does ros-kinetic-octomap depend on ros-kinetic-catkin? Looking at the release repository, it seems that somewhere between upstream and the final .deb a package.xml gets added with a run_depend on catkin. Why would catkin be needed at runtime?
2) Why is octomap even a ROS package (ie, with package.xml)? (as opposed to some other 3rd party libraries that are simply packaged and distributed)
I'm asking partly because this is installing a second catkin alongside my built-from-source version, but also to learn.
Interesting. I posted a comment on the devel repo hoping the authors would respond.
