Cannot locate node of type [velodyne_conversion_node]

[msh003]

Hello everyone I am trying to launch kitware, and I need to install velodyne_pcl. when I wan to make the Package I face an error: ERROR: cannot launch node of type [lidar_conversions/velodyne_conversion_node]: Cannot locate node of type [velodyne_conversion_node] in package [lidar_conversions]. Make sure file exists in package path and permission is set to executable (chmod +x) I have installed velodyne in this way : I cloned the git repo in my catkin workspace sources, and then built with catkin_make.

Please help me to solve this issue
