linker problem on hydro

Hey,

I'm trying to use your rep on raspberry pi with hydro. So I've instaled openni2 from your other repo and I have opencv2 and openCV as a third party AND from source.

I was wondering if your repo depended on the third party or external libraries (technically that would be libopencv on Ubuntu). Because when I try to compile openni2_camera I have

/usr/bin/ld: warning: libopencv_calib3d.so.3.0, needed by         /home/pi/tobot_ws/ros_mobile_ws/install_isolated/lib/libcv_bridge.so, not found (try using -rpath or -rpath-link)

collect2: ld returned 1 exit status
make[2]: ***     [/home/pi/tobot_ws/catkin_ws2/devel/lib/openni2_camera/openni2_camera_node] Error 1

If I don't have have the source installed and I have only :

/usr/bin/ld: note: 'cv::Mat::copySize(cv::Mat const&)' is defined in DSO         
/usr/local/lib/libopencv_core.so.3.0 so try adding it to the linker command line
/usr/local/lib/libopencv_core.so.3.0: could not read symbols: Invalid operation

if I have both the third party and the source install. I just don't know what went wrong with the linkers in both cases...

Thanks a lot !

EDIT :

I managed to compile by adding OpenCV linker in your CMakeList.txt (want me to pull it ?). Anyways, I just needed those linkers.
