How to select the Pilz Motion Planner?

edit

Hello,

i use MoveIt with ROS Melodic and Ubuntu 18.04. At a first stage i install MoveIt with binary. But if i got it right, the Pilz Planner isn't a part of this installation. So i build MoveIt from source without problems in another workspace (does this matter?). But how can i select this planner? If i change the pipeline in my move_group.launch, i got an error:

MoveGroup running was unable to load pilz_industrial_motion_planner::CommandPlanner

i downloaded the pilz_industrial_motion_planner_planning_pipeline.launch.xml into my launch directory. But i don't know what i have to do in addition to get thinks work.

Thanks for your help!
