[Insight-developers] Why is CMake networking?

[Paul Hughett]

I just updated from the repository and recompiled ITK.  I notice that
it is doing network DNS lookups.  Why?  What possible reason does ITK
have to talk to the network?  How do I disable the network options?
(We tend to get somewhat paranoid about computer security issues
here.)
