Noel Eck 39df7fd10f examples: Handle additional example dependencies
Dependencies added via 'TARGETS' in add_example are 'in addition to' the
dependency provided by the example filename.

    * Small change to examples/CMakeLists.txt to handle additional
      dependencies
    * Prefix 'interfaces-' onto the interfaces examples
