Joder! I think, I have found the missing piece - it's called
"link_directories()". I shouldn't have looked only at that pull request,
but at the newest version of the mentioned CMakeLists example.
I'm still a bit confused though. I can't remember needing this
"link_directories" addition so far. Furthermore, the ROS wiki even
recommends not to use it, since target_link_libraries() should suffice for
catkin and plain cmake packages - which is the case here (
Could someone shed some light on this please?
