Inconsistent version in incremental build

1. I built Creator's branch 11.0 before 3ff21fe3e15e9228c47e1bf248dd379cdb0e9d40 was merged.
2. I pulled, thus adding that patch to my sources.
3. I rebuilt in the existing directory:

   qt-cmake -GNinja -DCMAKE_BUILD_TYPE:STRING=Release -DWITH_DOCS=ON -DQTC_FORCE_XCB=ON -S ~/dev/src/creator-11/ && nice cmake --build . --parallel && nice cmake --build . --target docs --parallel
   

4. The build succeeds, but Creator can't load some plugins:
   
   Looks like they didn't get the version update.

This can easily be fixed by running

touch src/CMakeLists.txt

in the source checkout. Could something be added to the sources or project files so that an incremental build handles the situation automatically?
