Quando se segue o  tutorial do moveit o pacote moveit_tutorials não compila por não encontrar o ficheiro moveit_cpp.h.

A solução é não clonar a master branch mas sim a melodic-devel

So… to fix moveit tutorials  error on build:

cd ~/ws_moveit/src

trocar

git clone https://github.com/ros-planning/moveit_tutorials.git -b master

por

git clone https://github.com/ros-planning/moveit_tutorials.git -b melodic-devel
