Hi, It's correct that the file /usr/share/icons/hicolor/CMakeLists.txt should be deleted from the binary package, but I think that the file /usr/share/applications/org.flightgear.FlightGear.desktop has more entries (is better) that the file /usr/share/applications/flightgear.desktop so this one should be deleted or replaced by the former one.
Greetings. Ernesto
