[Omake] ocamllib build question

[micha]

one more question:
how can I get omake to build my ocamllibrary that way:

ocamlc -a -custom -o ocamllib.cma  a.cmo b.cmo -cclib "-lclib1 -lclib2"

i.e. include the -custom and OCAML_LINK_FLAGS into the OCAML_LIRBRAY 
target? omake is not using it when building a lib. (maybe adding a 
OCAML_LIB_LINK_FLAG variable?)

cheers
