The examples on the CABLE web page have never been tested with CableSwig
and are not supported.  I think your problem is (b).

I do not think any such document was created.  Unfortunately we do not
have time to support CableSwig as a separate project outside the ITK
wrapping process.  This is why documentation has not been created.
