 Unfortunately there is a critical mistake in their listed setting for
 using external modules.  I didn't figure it out until, like you, I web
 searched for someone else's working solution.

 WRONG:     `VTK_MODULE_USE_EXTERNAL_<name>`

 CORRECT:  `VTK_MODULE_USE_EXTERNAL_VTK_<name>`

 I really should ask them about that some time.
