[CMake] [OCaml] Allow building OCaml bindings out of tree.
That is, add build system support for building the OCaml bindings
against preinstalled LLVM libraries. This is important for package
managers such as OPAM, because OCaml libraries need to be built
against a specific OCaml compiler installation.
