Well, I'm trying to build a GUI for Sailfish, which is Qt5-based. But
Qt5 is not really supported by SyncEvolution. Although I've added some
workarounds in the backends, it would probably be nice if Qt5 was more
directly supported by the build system.
Most importantly, perhaps, is that I'm not sure how to cleanly build the
Qt D-Bus bindings. For example, syncevolution-qt-dbus.pc should contain
"Requires: Qt5DBus" instead of "QtDBus". What's the least hackish
way to
achieve that?
The build patches I've had to make so far include, with comments:

I don't know what the best way to handle Qt5 with autoconf/automake is
these days. I'm open for suggestions.
The existing Qt[5] D-Bus bindings are not used by anything at the
moment. Feel free to make whatever changes you need.

Would you prefer something like a --enable-qt5 switch? Something
explicit instead of this implicit "pick the most recent version that we
can find"? It might be a bit clearer, but other than that, such an
automatic fallback isn't that bad, is it?

Well, it seems a bit ugly too.
I've tried to look into things a bit more, and perhaps the existing
autotroll.m4 thing (which seems to call qmake) might still do the job
for QtContacts, at least. The main problem in that regard is that
SyncEvolution doesn't have any way to check whether any given Qt module
is available and fall back to another module if not.
With Qt5, there's no longer a "QtMobility", but a "QtPim" or
something.
So, to import QtContacts with autotroll, you should now just add
"+contacts +versit" to the main "need_qt_modules" thing, I think,
instead of having special imports for mobility. There's just no way to
know that beforehand with the current approach.
But given that knowledge of the Qt version is needed for
--enable-qt-dbus (where the syncevolution-qt-dbus.pc file needs to know
that it's now Qt5DBus, not QtDBus), and for --enable-kcalextended (where
the kcalextended modules aren't known to qmake at all, only to
pkg-config), perhaps it really is best to migrate to a completely
pkg-config-based approach, instead of using autotroll.
But, of course, a pkg-config-based approach would work for Qt4 too,
since Qt4 also has full pkg-config support. Perhaps it's best to just
use pkg-config all the way, and completely remove all uses of autotroll.m4?

I would be fine with that. Feel free to implement what works for you. I
don't think anyone else currently uses the QtContacts backend or the Qt
D-Bus binding library.
