set_margin* not declared in this scope

[raidiant]

I am running Ubuntu with Gnome-Shell recently installed.
I got gtk-3-0 and gtkmm and cmake writes all build files to gonepass/build with no errors.

Only when I actually try to make gonepass, make complains about functions not declared in the right scope.
I've checked the gonepass.dir/flags.make flags if the includes were alright and I've checked other files if the linking went right as well and so far nothing seems out of place.
