The other check is "gnatls -v". On this macbook I get

$ gnatls -v

and I'd expect your Linux version to look very similar, except that the
prefix (/opt/gnat-ce-2019) and the machine triplet
(x86_64-apple-darwin17.7.0) will of course change for your environment.

Note that the last set (Project Search Path) includes $prefix/share/gpr
and $prefix/lib/gnat; gnatcoll.gpr is in the first. So you should *not*
need to mess with ADA_PROJECT_PATH.

I can speak to the Mac environment, make an educated guess about the
Linux environment, but not so much about Windows.
