I discovered part of the problem.

With libopensync 0.22 the following are installed:

/usr/lib/pkgconfig/opensync-1.0.pc
/usr/lib/pkgconfig/osengine-1.0.pc

With libopensync 0.39 only the following is installed:

/usr/lib/pkgconfig/libopensync.pc

There are no osengine files installed with 0.39.

The following need patching to support both 0.22 and >=0.30:

tdepim/kitchensync/libqopensync/ConfigureChecks.cmake
tdepim/kitchensync/configure.in.in

I'm still testing (and ask others to do likewise), but here is my proposed patch:
