Package: flightgear Version: 1:2020.3.16+dfsg-1 Currently swift support is automatically disabled when building the package through CMake because the libevent dependency is missing.
Enabling this allows Flightgear to connect to swift [1]. swift connects to Virtual Air Traffic Networks like VATSIM [2]. [1] https://github.com/swift-project/pilotclient [2] https://vatsim.net/
