title: Include libusb in a package without the use of Macports
body: <p>I'm making an installer for my Qt app that communicates with the USB port.
  For the app to work, libusb must be installed. I can do that using macports in terminal but that might be a hassle for my users so I'm packaging the app using Apple's package maker tool.
  The question is how can I include libusb in a package so that the user won't have to use Macports? Or is there a way I can create a bash script that can install libusb?</p>
  
  <p>Thanks.</p>
