Have a working OpenCV app, and working rosserial_arduino pieces. Want to do some tracking with OpenCV + ROS. Integrated ROS code in OpenCV app and compiles clean with catkin_make.

But catkin_make Linking cannot find libs for cvCreateCameraCapture, etc.
Line from CMakeLIsts.txt target_link_libraries(myopencvtest ${OpenCV_LIBRARIES} ${catkin_LIBRARIES})

Running Indigo. Ubuntu 14.04 (actually Mint 17.1)

What do I need to do to get OpenCV libs to link in?

Please post the output of catkin_make and your complete CMakeLists.txt.

Thanks Geoff,

Initially wanted to keep the question brief.. As I was collecting the catkin_make output and CMakeLists.txt file I took another look at the CMakeLists.txt file and discovered that while I had the ${OpenCV_LIBRARIES} specified I had missed adding find_package(OpenCV).

Once I did that then the application linked fine.
