When building qtbase-6.0.0 with -DQT_BUILD_EXAMPLES=ON, sources of examples are not installed while compiled examples are installed, and I couldn't find any feature/option to enable it.

With qt5 when building and installing examples, sources of examples are installed too. It's used by QtCreator to show examples and interact with them. Without example sources, I'm not sure how QtCreator would be able to do this.

I think either example sources should be installed as well when examples are installed, or it should be a feature. Of course this could be done manually, but I think it'd be better if it'd be integrated into build system.

Last version where I checked that it worked as expected: 5.15.1.
