Camera plugin failed to Load

edit

Hey guys, im trying to run run a px4, gazebo and ros, with the typhoon_h480 example but i cant get the camera plugin working. But everything else seems to work.

I do the following commands in ~/src/Firmware/:

source /opt/ros/melodic/setup.bash

source ~/catkin_ws/devel/setup.bash

make clean 

make px4_sitl gazebo_typhoon_h480

getting error message:

[Err] [Plugin.hh:180] Failed to load plugin libgazebo_ros_camera.so: libCameraPlugin.so: cannot open shared object file: No such file or directory
