QGIS 3.22.8 - 3.26.0: WEBP support missing in GDAL 3.5.0 (OSGeo4W Standalone Installers)

[andreaerdna]

Using QGIS 3.22.8 or 3.26.0 installed via OSGeo4W Standalone Installers (both the previous *-3.msi and the current latest *-4.msi) with GDAL 3.5.0, it is not possible to display raster layer in GeoPackage with WEBP as tile format.

Sample zipped GeoPackage ​https://github.com/qgis/QGIS/files/9040031/saerheim_of.zip from ​https://github.com/qgis/QGIS/issues/49239.

Executing in the OSGeo4W Shell the following command:

gdalinfo saerheim_of.gpkg

results in the following warning:

Warning 1: Table saerheim_of contains WEBP tiles, but GDAL configured without WEBP support. Data will be missing

Using QGIS 3.22.8 or 3.26.0 installed via OSGeo4W Network Installer with packages updated to the latest versions (notably gdal package to 3.5.1), the issue doesn't occur.

So the issue is already fixed in OSGeo4w (next standalones with 3.26.1/3.12.9)

Reported to let other user quickly find a fix (installing or updating using OSGeo4W Network Installer) and to allow a possible check on why it happened and how to prevent it from happening in the future.
