Of course i tried the obvious. It made the project file syntactically
invalid. GPRbuild requires a string literal, and so does the BNF in the
GPRbuild User's Guide. Well it was GPRbuild 2015 that I tried it with,
but the GPRbuild and GPR Companion Tools User’s Guide 2016 still
requires a literal.

As long as that's the case I don't find Artifacts to be of much use for
a portable project. A cp command in the makefile works better.
