qgis-dev: "Could not load qgis_app.dll" after updating gdal-dev306-runtime to 3.6.0-52

[andreaerdna]

QGIS 3.27.0-Master (qgis-dev-3.27.0-265-597e8eebd4-1) doesn't start anymore after updating the gdal-dev and gdal-dev306-runtime packages to the 3.6.0-52-e10d39568c-1 version.

qgis_app.dll (in qgis-dev-3.27.0-265-597e8eebd4-1) depends on gdal306.dll, while gdal-dev306-runtime-3.6.0-52-e10d39568c-1 ships gdal-dev306.dll.

So I think qgis-dev package needs to be rebuilt after ​https://github.com/jef-n/OSGeo4W/commit/2a9ae2a11e62204086b3607556c7bb7012dccb1e.

Will solve itself once the qgis-dev nightly succeeds - but that's currently broken due to an issue in the pdal provider:

Maybe better to remove gdal-dev* 3.6.0-52-e10d39568c-1 and revert to 3.6.0-51-9aa17692a5-1 until qgis-dev is rebuilt?

gdal-dev would just reappear tomorrow.

Fixed in qgis-dev-3.27.0-266-0e23467727-1.
