Commit f1d2a49c747e69938f9f878f64620d7d6fc61b41 makes Qt.labs.location compilation conditional on config.opengl, but it doesn't seem to work. My Qt is built with opengl:

yet qmake doesn't detect it at qtlocation build time:
Configure summary: Qt Positioning: Gypsy GPS Daemon ....................... no WinRT Geolocation API .................. no Qt Location: Qt.labs.location experimental QML plugin . no Geoservice plugins: OpenStreetMap ........................ yes HERE ................................. yes Esri ................................. yes Mapbox ............................... yes MapboxGL ............................. yes Itemsoverlay ......................... yes
Changing "condition": "config.opengl" to "condition": "features.opengl" fixes it.
