[QGIS-Developer] How to build qgis on Windows 10

Tue Dec 27 00:23:59 PST 2022

Hi,

If you are building with vcpkg, it's worth having a look at QField which
also builds against vcpkg libraries with a quite recent vcpkg version and a
set of overlay ports.
https://github.com/opengisch/QField/tree/master/vcpkg/overlay

Best regards
Matthias
