You should be able to remove the references to cv and highgui
completely from ladybug2/CMakeLists.txt.  Executables built in that
package will already be linked against the exported libraries from the
opencv2 package, due to the ladybug2->opencv2 dependency.  See the
rosbuild docs for more on when not to use target_link_libraries():
http://www.ros.org/wiki/rosbuild/CMakeLists/Examples#Linking_against_libraries_built_by_other_ROS_packages
