I've only built nbdkit using mingw (not cygwin), and only using
cross-compilation from Linux.  It ought to work from Windows, but
you'd have to use mingw.

The full details of how to do that are in the README file under
"WINDOWS":

On this point, I use Fedora, but Debian or Ubuntu should work fine too.

I'd suggest trying to use mingw, either on Windows or from Linux, and
if it still fails, then post the error messages you see on the mailing
list.
