Building deja-dup for gnome 3.2, and control-center integration

[Jordi Chulia <jorchube gmail com>]

Hi. 
I'm an archlinux user, and I want to install deja-dup 20.0 (by compiling
it first) on gnome 3.2.

However, the integration between gnome-control-center and deja-dup is
missing, since in gnome-control-center 3.2 there are no more headers to
create custom modules.

How is deja-dup supposed to be built in order to have it integrated in
the control-center?

Thank you.
