[Paraview] Qt dependency

[David Doria]

Does Paraview depend on Qt for anything except the UI? I am trying to
install paraview on a server that does not have a graphics
card/monitor, so a GUI won't be much use (I'm just trying to run
pvserver). Could there be a "Build GUI?" option in cmake so that it
can be built without Qt installed? The server is running an old
version of redhat and it's giving me grief trying to install Qt.

Thanks,

David
