Build and installation

• macOS Catalina: ParaView-5.7.0-MPI-OSX10.12-Python2.7-64bit.pkg” can’t be opened because Apple cannot check it for malicious software.
• ParaView build fails on arm clusters
• Catalyst: Node class from vtkPlotEdges.cxx name-collides with linked simulations (SPARC)
• Follow-up from "Fix paraview-config script"
• Spack ParaView should contain '-DVTK_ENABLE_KITS:BOOL=ON'
• Runtime crash on Cray, Debug builds
• paraview build fails first time through due to cinema-related build order issue on stria/ARM
• Remove unnecessary Python 2 conflict in ParaView's Spack file
• Spack: ParaView installs libraries to prefix/lib64 but creates empty prefix/lib making ParaView's modulefile invalid

Third-party library updates

• Upgrade ParaView CGNS version to 4.0.0

Miscellaneous bug fixes

• Segfault calling VisRTX_GetContext() at startup
