Sorry for the late response. Yes that's the same as passing
-DPYTHON_LIBRARY. Passing the .lib file like you do sounds right to
me, but I'm not 100% sure as I've never built on Windows (on Linux you
pass the .so file).
Maybe one of the VTK devs on Windows can jump in.
PS. Keep the mailing list address in your replies so that everyone can
see, I added it back in this mail. DS.
