Hi previous me. I am still not sure how it works, but somehow I could make it work.

1. delete build and devel folder and recompile

Even after changing cmakelist, catkin_make still use previous package (I don't know why). Delete these folders can refresh some information and solve this problem.

2. Exclude /opt/ros/kinetic/lib/libopencv_core3.so.3.2.0; from catkin_LIBRARIES

After you told your opencv location to catkin_make, there is still ros-opencv reference information in that file. So, just delete that files using following command.

string(REPLACE "/opt/ros/kinetic/lib/libopencv_core3.so.3.2.0;" "" Modified_CLIBS "${catkin_LIBRARIES}")

Then, use this newly modified Modified_CLIBS instead of catkin_LIBRARIES.

For more detail, please look at my sample CMakeList.txt in test project. https://github.com/YoshiRi/ros_opencv_conflict

Ex. sometimes you need to exclude whole ros-opencv packages

I found in my another project, the method <2> do not work. So, I tried next ugly code, and it worked.

Currently I just get this list from MESSAGE("${catkin_LIBRARIES}") but I should look for the better way to do this automatically. You can check which Opencv version your generated code depends on via:

cv::getBuildInformation()

And I noticed it still using ros-opencv as a default by checking output fromthis result sometimes differ from following command:

std::cerr << "OpenCV version : " << CV_VERSION << std::endl;
