Description The Feren OS Dev 2019-12-26 15:07:10 UTC

SUMMARY
Global Themes that have an SDDM theme as part of their pack do not get installed to ~/.local/share/plasma/look-and-feel if SDDM is not installed and /usr/share/SDDM therefore does not exist.

STEPS TO REPRODUCE
1. Remove SDDM and any SDDM Themes left over
2. Go into Global Theme -> Get New Global Themes...
3. Install a Global Theme that should pull in an SDDM Theme such as Layan or Sweet

OBSERVED RESULT
The Global Theme isn't installed to its proper place at all and therefore doesn't appear in Global Theme despite being "Installed"

EXPECTED RESULT
The Global Theme will be installed to the correct location minus the SDDM theme it provides users with and will be in Global Theme

Git commit c3e8c13e6c625fcf765f64a868f0c4d8b4544e4a by Alexander Lohnau.
Committed on 14/09/2022 at 10:06.
Pushed by alex into branch 'master'.

Ignore sddmtheme dependencies if we do not have the knsrc file installed

Otherwise, global themes that have this dependency can not be installed where the SDDM-KCM is not installed.
