[kde-freebsd] INSTALLS_ICONS and qt4 software

[Oliver Heesakkers]

I took maintainership over a port that was written for qt4 (non KDE). The 
Makefile for this port specifies:

INSTALLS_ICONS= YES

>From ports/Mk/bsd.gnome.mk I learned that this is used to make sure icons will 
show up where needed.

This very Gnome-specific setting is responsible for dragging in a lot of 
Gnome/GTK specific ports, which is something I don't particularly like.

Am I correct in understanding that KDE4 doesn't require INSTALLS_ICONS? I 
tried it and the port seems fine without INSTALLS_ICONS

When a Gnome-user installs this port, would he/she require INSTALLS_ICONS to 
have the icon show up?

If so, is there a standard way for the ports Makefile to check for the 
existence or use of Gnome so I can optionally set INSTALLS_ICONS? I think it's 
overkill to make an actual OPTIONS= line for it.
