-ccopt <opt> C option passed to ocamlc -a or ocamlopt -a only
-custom disable dynamic loading
-dllpath <dir> Add <dir> to the run-time search path for DLLs
-I <dir> Add <dir> to the path searched for Caml object files
-failsafe fall back to static linking if DLL construction failed
-ldopt <opt> C option passed to the shared linker only
-linkall Build Caml archive with link-all behavior
-l<lib> Specify a dependent C library
-L<dir> Add <dir> to the path searched for C libraries
-ocamlc <cmd> Use <cmd> in place of \"ocamlc\"
-ocamlopt <cmd> Use <cmd> in place of \"ocamlopt\"
-o <name> Generated Caml library is named <name>.cma or <name>.cmxa
-oc <name> Generated C library is named lib<name>.so or lib<name>.a
