In a sense, QT_INSTALL_DATA looks like a better candidate,
it's set by ./configure --datadir, so it sounds very much like this.
However, its default value doesn't work for us: it defaults to
QT_INSTALL_PREFIX and not to QT_INSTALL_PREFIX/share.
That's quite unfortunate (but impossible to change, I assume it would break
stuff, e.g. if anyone installs stuff in a subdir of the root and then expects
to find it with QLibraryInfo::DataPath + "/subdir" - in a controlled
environment where they know --datadir isn't used...).
So yeah, I guess QT_INSTALL_PREFIX/share is your best bet.
But we'll see if other QtCore people have a better idea.
PS: the last patch I saw didn't use XDG_CONFIG_DIRS, don't you want that as
well? The idea of XDG_*_HOME floated around too, but I don't know if that one
is as useful, it's irrelevant to the way things are installed, so I would skip
that for now.
