Fails to build due to: libkimera_semantics_ros undefined reference to cv::String::deallocate() #71

Fails to build with the above error on Ubuntu 20.04 when following the instructions in the README.

The kimera_semantics_ros library seems to be missing linking against OpenCV.

I added the following lines, which link against the same opencv3_catkin package used in Kimera-VIO-ROS (https://github.com/MIT-SPARK/Kimera-VIO-ROS/blob/master/install/kimera_vio_ros_https.rosinstall):

find_package(opencv3_catkin REQUIRED)
target_link_libraries(${PROJECT_NAME} ${opencv3_catkin_LIBRARIES})

After these lines were added, the ROS stack successfully builds with Noetic on Ubuntu 20.04.

thank you, your note about building on Ubuntu 20.04 is really helpful.
