macdeployqt needs to find and link relevant libs imported by qml.
There are 4 components which are using qml:
- KDE Connect qml application
- KDE Connect sms application
- Presenter plugin
- KDE Connect sftp browser
But 1 and 2 are linked with libkdeconnectcore, thus they are indirectly linked to qca-qt5. So, qmldir of 1 and 2 will be added after KDE Connect getting rid of qca-qt5 :)
