I think there is some problem with the system-supplied qtlocation5 thing.

First I removed the libqt5location5 package and its dependencies. Then cmake 
failed, because it couldn't find qtlocation. Then I reinstalled qtlocation5-
dev and deleted the googlemaps and the subsurface/build directories.

Now it compiles and runs, but the map widget doesn't show: "MapWidget.qml 
failed to load! The QML modules QtPositioning and QtLocation could be 
missing!". That's not ideal, but OK for now.

glmark2 runs fine.
