I'm actually working with Anjuta.
Anjuta is Makefile-based.

The problem is that if I change something I need to do a 'git pull',
which overwrites
the "pkg-config --includedir gtk+2" to be "pkg-config --includedir gtk+3".

So I'm thinking to just create an environment variable - something
like "USE_GTK3",
export it on the machine set for GTK3, then fix the Makefile.in for my project.
Then this will be kept independently of which version I have installed
on the system.

Or is there a better and simpler alternative? Maybe pkg-config has
something like
"set the current GTK+ version to be GTK+3"?

Thank you.
