I'm trying to use opencv on kinetic. As per 4.1 on this wiki, I had to add a dependency on opencv2 and find_package in the CMakeLists.txt [instructions here].

This is my edited CMakeList.txt. I'm getting

 'CMake Error at pc_side/CMakeLists.txt:19 (target_link_libraries):
  Cannot specify link libraries for target "pc_side" which is not built by
  this project.

Please post the full error output copied from your terminal, not just the main error text.

The target_link_libraries tag is used to add the library dependencies of a specific binary (executable or library) that is built in the package, not the package as a whole.

If your trying to use OpenCV 2 on ROS kinetic it's already included, adding a dependency on the cv_bridge package should be all you need to do. Then you just need to add the correct header files and start using OpenCV in your code.
