How about a warning if QCA can't find _any_ plugin telling the user to
check what he has in his QT_PLUGIN_PATH?

Because they might want to use their system Qt.

Well, because if you want to start hacking on QCA that won't work. Also
currently the tutorials on techbase tell people to build kdesupport,
which includes QCA and quite some people fail at that stage because QCA
can't write to /usr/. Of course they could also build qt-copy, but thats
not required and building qt-copy is quite some extra effort.
