The expectation is also that data is persistent, if we don't change
the default perhaps we can at least add a warning at configure time to
advise that data will be downloaded multiple times (the default is
each build tree?) I would love to see a default parallel to the source
tree, like VTKExternalData or something, but it seems like you are
strongly opposed to that.
