The native Linux Kde file dialog is not displayed if non-system Qt libraries are used in the project

Hello!
Please tell me what this problem may be related to: the native Linux Kde file dialog is not displayed if non-Qt system libraries are used in the project (for example, if Qt libraries are used that were installed through the Maintenance Tool).

(for example, if Qt libraries are used that were installed through the Maintenance Tool).

Because then the KDE libraries/plugins can not be found (or are there but using an incompatible version) and therefore the KDE file dialog can not be used.

Thanks!
Is it necessary to build all the KF5 libraries from the sources additionally?

Since the Qt minor versions are backward compatible, it should be enough when the KDE libs are built with the same or an older Qt version than the one you use. You just have to point Qt the the correct QT_PLUGIN_PATH.
