[vtk-developers] VTK ExternalData default object store

[Robert Maynard]

That is an edge case for a small set of VTK / ITK developers. Nothing
stops use from having VTK use VTK_TESTING_DATA_STORAGE and asking
people that use ITK and VTK to set both. We could also check if
ExternalData_OBJECT_STORES is set and fill VTK_TESTING_DATA_STORAGE
from the variable.

I still believe that the name is a bad name in the context of VTK developers.
