more and more KDE projects are preparing for Qt6 and ensuring no outdated code in new patches by setting -DQT_DISABLE_DEPRECATED_BEFORE=0x050f00 (so hiding all API deprecated up to 5.15).
When it comes to those using Grantlee and thus having available as last released version 5.2.0, they run into the issue
of SafeString using depecated QString enums in the API. While the master branch of Grantlee has a patch to handle that deprecation, that has two issues:
QT_VERSION is a string active both during build of Grantlee itself,
but also when 3rd-party uses the public header of SafeString.
In case one is Qt < 5.14 and the other >= 5.14, things will fail.
it violates the ABI promise of the shared library version.
This patch should fix that. Once in, it would be great to have a 5.2.1or 5,3.0 release of Grantlee soonish, so users can make use of the 5.14/15-enhanced API.
