cmake actually runs the configuration.
In, ccmake (the first 'c' is for "curses", the GUI that it uses), you
can setup parameters like include directories and boolean flags, etc.
Then you press 'c' for configure (a couple of times, until it gives
you the option of 'g' for generate). Then press 'g' for generate.

If there isn't a "How to build VTK" document somewhere (which I'd bet
there is?), we know you have all the steps down, so I think you just
volunteered to write it :)

I didn't see one in a quick glance through:
http://vtk.org/VTK/resources/software.html
and
http://vtk.org/VTK/help/documentation.html

When we get something together it should definitely be added in one of
those places. We shouldn't make people learn cmake just to install vtk
(although it is very useful and I'd recommend learning it a little
bit).

Thanks,
