[Geary] error: Package `webkitgtk-3.0' not found in specified Vala API directories or GObject-Introspection GIR directories

[Federico Bruni <fede inventati org>]

Hi all

I cannot compile current master (the last time I compiled it 
successfully on my laptop was around mid December).
I'm on Fedora25. I've started with `make distclean`, in order to start 
the build from scratch.
The configure runs fine, without any error or warning. But when I run 
make I get this error:

I have this package installed:

$ dnf info webkitgtk3-devel.x86_64 | grep Version
Version     : 2.4.11

Thanks in advance for any hint
