How can I get ocamlbuild to include paths to external libraries when
building documentation?
Ocamlbuild gives me errors when building documentation, when my interface
files contain references to an external library. I have set up my plugin and
_tags file to correctly compile the code, but cannot get the documentation
to work. The command that ocamlbuild executes is [1], which gives error
[2]. Module M is declared in an external library. I get no errors if I
manually type [3], where ~/mylibs contains the appropriate library.
[1] ocamlfind ocamldoc -dump a.odoc a.mli
[2] Unbound module M
[3] ocamlfind ocamldoc -dump a.odoc -I ~/mylibs/ a.mli

Thank you.
