Actually, my Makefile.coq contains that line:

VOFILES0=$(patsubst theories/%,%,$(filter theories/%,$(VOFILES)))
VFILES0=$(patsubst theories/%,%,$(filter theories/%,$(VFILES)))

And the opam-installed iris (which effectively just runs "make install")
does have the source files:

> $ ls -R /home/r/.opam/coq-8.6/lib/coq/user-contrib/iris

I actually remember spending some time a while ago to make this work
(for different reasons that yours).  I also remember the missing
VFILES0, but now that seems to be fixed...?
  Actually, I noticed I am not using Coq 8.6, but "8.6.dev", which is to
say I am using the development version of the 8.6 branch from some point
in time some months ago.  If you are using opam, could you try that and
see if it helps?

Kind regards,
