Don't know about licensing, but distrubiting the files depends on whether or not your program is open source. If it's open source, then I think the examples are optional but all libraries, headers and includes should be included along with the binaries. If it's not open source, then just the binaries are needed. I wouldn't have thought that you would need to include the examples and suchlike. The licensing and copyright files obviously need to be in any package.
That's just my take on it, you'll need to rely on Ian for the official standpoint.
