I use swig, which is very flexible, works with multiple languages, has
fairly easy/mechanical interface definitions[*], and generates Lua
interfaces which usually capture most of the nuances of the C++
interface (e.g., overloading, inheritance).

[*] It looks at C++ declarations directly, so theoretically you can just
feed it your existing .h files and have it generate the appropriate
interfaces; in practice, you often want to give it slightly massaged
versions, but it's pretty easy to do this.

The downside is that the code it generates can be a bit bloated.  So
it's maybe not what you want for a small embedded app with simple
interfaces.
