These errors are from the Vala compiler, rather than the C compiler. Although it is a good idea to check your 
installed libraries and C headers, as you have done, you should focus on the Vala side first. The Vala 
compiler is saying it can't find Seat.

One possibility is the Gdk namespace has not been brought in to scope with the 'using' keyword. The source 
from Dino:
https://github.com/dino/dino/blob/master/main/src/ui/conversation_summary/message_textview.vala
shows that it is in scope. So unless you've modified the source that shouldn't be the reason.

Gdk.Seat is defined in gdk-3.0.vapi. You should check that the VAPI is in the appropriate search path and 
that Seat is defined. From https://developer.gnome.org/gdk3/stable/GdkSeat.html it looks like GdkSeat was 
added since Gdk 3.20. GNOME 3.20 and libraries were release March 2016. That would tie in with a minimum Vala 
version of 0.32.0 - released 21 March 2016.

I hope that gets you further along the way,
