Bug#1146727: kstars: Compile with QT6 and KDE 6

[Davide G. Borin]

Source: kstars
Version: 5:3.8.4.1-1
Severity: normal

Dear Maintainer,
 kstars developers recommend to compile it with QT6 and KDE 6.
This will also avoids huge dependencies to all users of KDE/Plasma 
current stable version.

Thanks.
