I have CC'd Richard Jones on this message. He has done the packaging
for most of the available Fedora OCaml RPMs and can hopefully provide
some input.
Another option may be to add a "make ocaml-findlib-install" or similar
OCaml specific target. The ocamlfind [1] tool provides a means to
cleanly (un)install OCaml libraries and ease their use in compilation
and linking of OCaml programs. This could potentially be useful both
for people who have OCaml installed in a non-standard location and
possibly for packagers as well. Or perhaps at least one of the OCaml
packages in Fedora (the Cairo bindings) uses ocamlfind for
installation of the package files according to the package SPEC file.
My cmake knowledge is still extremely limited, but I would be happy to
assist where I am able.
