AFAIK, FSF Debian GPS is still GCC 4.8, while the actual GNAT GCC 5.x. 
Basically, there is no usable GPS for Linux, IMO.

There is no official release of GtkAda for GTK 3.x for Linux.

Then, there are serious issues with the gprbuild under Linux.

You should use gnatmake regardless warnings it issues. That in turn 
precludes GPS. (In earlier version you could fool GPS by writing a shell 
script named gprbuild that calls gnatmake from inside. It does not work 
well now.)

You have a broken project file.

I do developing under Windows and build the results under various Linux 
distributions and machines. Everything works, including GtkAda.

You don't need to fix Path variables to make it working.
