1. This issue occurred unexpectedly, viz. no changes to the project config or the vcpkg manifest file.
2. vcpkg install directory is F:\tools\vcpkg. This has been mapped to V: to workaround failures building Qt, parts of which seem to hit a long path issue.

Have tried git pull and vcpkg update without any success.
All help with this appreciated.

Should be fixed with #37396

Thanks. Subsequently, there was an error in harfbuzz which failed in gen-harfbuzzcc.py at

Traceback (most recent call last):

This was fixed by setting VCPKG_ROOT to the actual location of the VCPKG installation. Remains to be seen how Qt reacts with these changes.

Thanks for the quick response.
