Yep, "gtk-osx" has a very specific meaning here, and that's fine. 
But I hope I'm not too far off-topic in commenting on a couple of 
points. (Valerio: if you want to follow up, best to do so off-list.)

There are some existing binary packages for macOS with X11. The R 
project has one at 
http://r.research.att.com/libs/GTK_2.24.17-X11.pkg and another is
at http://ricardo.ecn.wfu.edu/pub/gretl/GTK+.framework.dmg .

Not so. See https://github.com/tpoechtrager/osxcross , a brilliant 
piece of work. Cross-compiling on linux via clang is not too 
difficult; I do it for gretl ( http://gretl.sourceforge.net/ ), a 
rather complex GTK application.
