Hi.
I have some weird circular dependencies build issue using ocamlbuild.
Something like:
Circular dependencies: "A.cmo" already seen in
[ "A/C.cmi"; "A.cmo"; "B/D.cmo" ]
I haven't been able to trim it down to a simpler reproducible example.
How are circular dependencies determined and how are dependency
information managed inside the _build/ folder?
More specifically, A and B are module packs (for-pack tag in _tags) and
I do not see a .depends file for the top pack module, so I'd like to
know where this information is kept.

I see this happen if I forget to specify a sub-module in an .mlpack
file, but use it anyway (so it's pulled in as a dependency to the pack,
but not actually explicitly part of the pack).
So just try listing all the modules you use explicitly in the .mlpack and
see if the issue goes away.

Yes, that's it.
