Do packages have to be in the catkin source space?
Hi there! Been trying out ROS and I'm simply amazed just how detailed the tutorials have been. One thing that's been puzzling me though is that catkin_make (and in my case, catkin build) seems to also look into the /opt/ros/kinetic/share folder on top of the source space. What is the reason for this? Is the latter space exclusively for packages I write while the former is for packages developed by other parties?
Many thanks.
