Optional annotation for implementations of C++ function wrappers
that may be exposed to Rust. You may for example need to provide

if Rust code from one shared object or executable depends on
these C++ functions in another.

Any additional headers to #include. The cxxbridge tool does not
parse or even require the given paths to exist; they simply go
into the generated C++ code as #include lines.
