@QT_MODULE_PLUGIN_INCLUDES@
Be verbose on plugin inclusion, easy patch point for distros TL;DR: This creates two changes: 1. Makes the plugin inclusion status more visible for builders for both Qt itself and applications. 2. Allows a simple patch-point for distros to change the default (perhaps not ideal, but good enough). 3. Does not changes the current behavior. As discussed both in the mailing list and privately with Alexandru Croitor and Joerg Bornemann this makes a lot os sense for Qt on static builds and when trying to find where the plugins are so they can be easily packaged up in order to distribute a build with all the dependencies on it. But at the same time it makes no sense for distributions building the libraries in dynamic mode as it forces unnecesary build time dependencies for for both Qt and applications like QML modules or even PostgreSQL! [0]. [0] <https://sources.debian.org/src/martchus-qtutilities/6.10.0-1/cmake/modules/QtConfig.cmake/?hl=35#L35> Other approaches have been considered like not shipping specific CMake files, but this depends on the packager finding the right ones at the right time, and does not allows end users to change the behavior if they happen to need it.

CMake: Create and include plugin packages in shared builds Previously QtModulePlugins.cmake files were only created and included in static library Qt builds. Having the targets available in shared library builds would be useful for custom project deployment purposes. One could query the location of the plugins or use various generator expressions referencing their location. Ensure we always generate and include the QtModulePlugins.cmake files regardless of the build type. Allow opting out of including the files by setting QT_SKIP_AUTO_PLUGIN_INCLUSION to ON, just like we allow for Qml plugins with QT_SKIP_AUTO_QML_PLUGIN_INCLUSION.
