[Insight-developers] Why is CMake networking?

[Miller, James V (CRD)]

CMake does a hostname and a nslookup and a uname to setup some variables for testing. Basically, the
site name (should be the domain name but is currently the hostname) and buildname are constructed
automatically, and then used to create directory names.

Once this done once, I think you should be able to override the values in the cache if you do not
want to "export" these variables.

All we are really looking for is information like

uphs.upenn.edu
irix65
gcc

etc. 

I don't want to export hostnames but this is what CMake currently has implemented.

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.)

runing /bin/hostname

runing /usr/bin/nslookup mercur.uphs.upenn.edu

Note:  nslookup is deprecated and may be removed from future releases.
Consider using the `dig' or `host' programs instead.  Run nslookup with
the `-sil[ent]' option to prevent this message from appearing.
