In fact, I was not aware of two things.

The first thing is that gtkmm and gtk+ version numbers must match to work together and to compile fine.
For example, I was able to compile with gtk+-3.8.2 and gtkmm-3.8.1 probably because the version number is the 
same (3.8).
It is just my guess so tell me if it is wrong.

The second thing is that it exists a newer version of gtkmm.
Indeed, when I go on [1], I see that the last stable version is gtkmm-3.10 whereas on your link [2], the last 
stable version seems to be gtkmm-3.14.0.
I guess that [1] is not always up to date, but tell me if I misunderstand.
