The KConfig unittests rely on DBus nowadays (for change notification). This is turned off on Android, and is a cmake option elsewhere, defaulting to ON.
On Windows, I'm sure a lot of other modules rely on DBus, so I suppose it's just a matter of starting the dbus daemon for those modules that need it? Currently the kconfig tests fail for lack of dbus: 21:55:23 ERROR: The process "dbus-daemon.exe" not found. https://build.kde.org/job/Frameworks/view/Platform%20-%20WindowsMSVCQt5.15/job/kconfig/job/kf5-qt5%20WindowsMSVCQt5.15/217/console -- David Faure, fa...@kde.org, http://www.davidfaure.fr Working on KDE Frameworks 5
