EDIT

Your first CMake target is name wificamp; therefore your linking command should be:

target_link_libraries(wificamp ${OpenCV_LIBRARIES})

You can also combine this with the linking command that links your exectuable against the catkin libraries:

target_link_libraries(wificamp ${catkin_LIBRARIES} ${OpenCV_LIBRARIES})
