23 From a couple minutes of poking around:
25 strings /usr/lib/qt4/ | grep Build.key
27 strings some-other-file | grep buildkey
29 Which comes back with seemingly everything build against Qt4... But I
30 don't know how to tell which ones qualify as a "plug-in"...
32 Typically when I rebuild Qt4 I also rebuild kdelibs, PyQt4, and my
33 themes... in my case that is gtk-engines-kde4, gtk-engines-qt, and all
34 qtcurve packages. Seems to work for me.
