ROS package not found after catkin_make

Hello :)

I'm quite new to ROS and tried to install a package (laser_line_extraction) from github. I completely followed this instruction https://wiki.nps.edu/display/RC/Setti... step-by-step. But after creating the package with catkin it's there as a directory but can't be found with "rospack find ...".

[rospack] Error: package 'laser_line_extraction' not found

Online I found something about "sourcing the launchfile" but no explanation on what this means or how to do it.

Can anyone help?
