I added support for this on the 0.9.8.ocamldep branch.  I'm fairly sure 
it is stable, but we should examine it more closely before merging to 
the trunk.  The relevant parts are:
    - the find-targets-in-path-optional(<path>, <filenames>) finds
      the specified targets, even if the files do not exist yet.
    - the ML scanner calls ocamldep with the -modules option, and
      pipes it to an internal postprocessor.  This is all done
      in OCaml.om

It is all transparent, there is no need for OCamlGeneratedFiles, etc.

For now, I've added the ocamldep-omake bytecode executable to OMake.

It is (I believe) a bit slower, perhaps because ocamldep-omake is bytecode.
