Qt Location support on Windows with MSVC

[srcejon]

Qt Location 5 on Windows with msvc doesn't support the Mapbox GL plugin (because mapbox-gl-native couldn't be compiled with msvc. However, thanks to @dpaulat maplibre-gl-native can.). So is it possible to use maplibre-gl-native in Qt Location?

The readme in platform/qt says 'This is the foundation for the Mapbox GL plugin' - but it doesn't appear to be the plugin itself. Qt seems to want qtgeoservices_mapboxql.dll, but QMapboxGL.dll is built (which doesn't include qt_plugin_instance so doesn't appear to be a plugin). Any ideas how to proceed?

It seems Qt has a fork of mapbox-gl-native in its source tree.

With a few changes, as described here, it seems it is possible to get Qt Location to build with maplibre-gl-native.

I recommend to switch to Qt6. There is a patch that builds also on MSVC 2019 in here, with the exception that one Boost library bug has to be applied.
