How to use GPU enabled OpenCV with ROS Kinetic?

Hi, I want to use CUDA enabled OpenCV with ROS. I have kinetic which already has one OpenCV 3.2 but it is not cuda enabled and also doesn't have extra modules of opencv_contrib. For this reason, I built a new OpenCV in /usr/local with CUDA and opencv_contrib enabled and I got this new OpenCV working.

Now I have been through most of the question for implementing custom OpenCV with ROS and somehow, I am able to compile (catkin_make) my package using with custom OpenCV but when I run it, with rosrun, it again uses kinetic opencv and shows cuda not enabled. Any help in this regard would be appreciated.

P.S - I am able to use extra modules even with kinetic opencv also (It just worked by itself). Only that cuda part is not working for me.

I got this thing working now. I followed this : Similar Question

The key was that I had to rebuild all other packages also which were dependent upon OpenCV (vision_opencv which has cv_bridge). Also, in my cmakelist file, I have include all OpenCV packages and libraries for my project before the catkin packages. I dont know currently if it played a major role, but atleast its working now.

If the problem still persists, please check your $CMAKE_PREFIX_PATH and $LD_LIBRARY_PATH. They should have the /usr/local (where your custom OpenCV is present) path before any of the ROS paths.
