CMake: Fix 'Cannot find source file' error with older CMakes
Configuring a static qtdeclarative with CMake versions older than
3.18.0 fails at generation phase with
CMake Error at cmake/QtExecutableHelpers.cmake:28 (add_executable):
Cannot find source file:
some_path/some_target_plugin_imports_Gui.cpp
Marking the generated file as GENERATED explicitly solves the issue.
Pick-to: 6.1 6.2
