BUG: undefined references to everything

[florisvb]

Issue description

I am trying to get this package (branch: master) to work on a system running Ubuntu 20.04 with ROS Noetic. What I get to the catkin make step I get a long sequence of undefined references.

Code example about how to reproduce the issue

cd ~/catkin_ws && catkin_make clean && catkin_make && source ~/.bashrc

Hardware setup description

Ubuntu 20.04 x86_64

Runtime information

I have pylon 6.2 installed, I have also tried with 6.3 and 7.3. All of the pylon viewer versions work. 
I am running ROS Noetic.

Is your camera operational with the Basler pylon Viewer on your platform?

Yes

Hello @florisvb
The master branch support the ROS version of the pylon driver, this is a deprecated version, we are not maintaining anymore.
I suggest that you upgrade to the ROS2 galactic version if you want to stay under Ubuntu 20.04, and thus upgrading your pylon version as well.
