Qt 6.10.0 beta3

Steps to reproduce:

• install Qt 6.10.0 beta3 and webengine (+ ninja)
• configure and build the example and do make install

 /home/qt/Qt/6.10.0/gcc_64/bin/qt-cmake -S /home/qt/Qt/Examples/Qt-6.10.0/webenginequick/quicknanobrowser -B /home/qt/Qt/Examples/Qt-6.10.0/webenginequick/quicknanobrowser/bld_gcc_64 -GNinja

in the build dir:
cmake --build . --parallel -j 8
and:
cmake --install . --prefix /home/qt/Qt/Qt_6.10.0/example_install

Expected result:

The binary 'quicknanobrowser' is getting copied to the 'example_install' directory when doing cmake --install step.

Actual result:

The binary is not getting copied to the 'example_install' directory and e.g. deploying to an embedded device fails (with Boot to Qt 6.10.0 beta3) because the binary is missing. 

Building and running via Qt Creator 17.0.1 on Linux desktop works.
