It this really so hard? I have been suggesting, in vain, to _create a
tarball_ and insert said tarball into a package repository precisely because
OP is stuck.
You are not helping by reiterating the OPs position three times over.

Yes. We used that for years via drat. And again, no magic.
R tools essentially do that automagically (if dependencies in visible repos
you declared in your session, obviously -- no magic lamps or powder
dust). The dependencies get resolved. CRAN is no different if you consider
how eg BioConductor gets resolved automagically (and again, see the R Journal
paper for long details if you need them). Works for source or data packages,
the latter is discussed there.
