I agree that this step should not be required to do manually (though
it seems to be common (e.g. Paraview requires it:
http://www.paraview.org/Wiki/ParaView/Git/Download in the form of
clone --recursive).

Matt, is there a way to have CMake check for the existence of the
submodules and run the submodule command automatically? Or perhaps
CMake could just always run that command automatically, as I believe
git basically does nothing if it is already in a good state?
