I managed to build by installing another separate Qt5 library of later version than the default one. However while running some other issues appear. I think it is not so straightforward to make this package work with ROS kinetic so I have moved on to use another machine with 18.04. Thanks!

Thanks for trying. You could add CATKIN_IGNORE to the rviz_polygon_tool folder and use the coverage planner without the RVIZ tool.
