Static build of Qt + Wayland

[Herzenschein]

Hello, I'm relatively new to Qt, so forgive my ignorance.
I'm doing this as a learning experience.

I have done the following steps to build Qt6.5 (dev) statically:

./init-repository --module-subset=qtbase,qtdeclarative,qtshadertools,qtwayland
./configure -prefix ../qt6dot5 -static -release -nomake tests -nomake examples
cmake --build . --parallel
cmake --install .

(I think I also tried it with Qt6.2, so I don't think the Qt version is the issue, but I can try again if needed.)

It builds successfully after installing Mesa's OpenGL and the needed xcb/X11 development libraries.

Now, if I import this self built Qt6.5 in QtCreator and run my applications, it works okay, on XWayland. I'd like my apps to run natively on Wayland (I'm on Linux, KDE Plasma 5.26.2, the Wayland compositor is KWin). This works fine with dynamic linking IIRC.

I figured I needed a qt_import_plugins() call in my CMakeLists.txt to INCLUDE a Qt::QWaylandIntegrationPlugin, since I need to manually add plugins when using a static build. But then I get this error with QT_DEBUG_PLUGINS=1:

qt.core.plugin.factoryloader: ignoring "org.qt-project.Qt.QPA.QPlatformIntegrationFactoryInterface.5.3" since plugins are disabled in static builds

I can't figure out how to proceed from there. My guess for the next step would be to use QT_WAYLAND_SHELL_INTEGRATION in some way, or maybe I'm missing something for QtWayland.

@Herzenschein I've solved it by adding Qt${QT_VERSION_MAJOR}::WaylandClientPrivate
to target_link_libraries() of the app.
Also add -system-freetype -fontconfig to configure, to not see squares instead of letters. And -no-prefix instead of -prefix ... makes it easier, since you wont have to install.
