Icons of some installed programs using sbopkg is missing in KDE/XFCE; Slackware64
I've installed some programs using sbopkg, some have icons like "Skype" or "gpodder" but some don't, like "lyx" or "anki". Whenever I search for them in KDE's application launcher, I just see "Run anki" or lyx (which successfully starts the program) , but no Icon itself. So I can't for example search for them manually through menus (of KDE or XFCE) or put them in the Desktop or whatever. Why is that?
