I have Debian 8 here, so a trifle out-of-date.

It looks as though you can get the pre-built libraries you need (for 
buster/gnat8) by installing libgnatcoll-xref18-dev (this includes sqlite, xref).
You don't need gnat_util, because Debian uses instead gnatvsn, which will be 
automatically installed as a dependency, so edit this line out of 
ada_mode_wisi_parse.gpr.gp.

I don't think you'll need this.
