[Paraview] error when compiling Paraview 5.4 macOS 10.13

[Cory Quammen]

Alas, this fix was made after ParaView 5.2 was released.

If you really need ParaView 5.2 instead of 5.3 or 5.4.1, you can apply
the patch in my previous email to the VTK subdirectory in the ParaView
source code. As you can see, just two lines need to be modified, so
you could easily do this manually.

Hope that helps,
Cory
