arena.h failure
arena.h is failing with the Intel compilers (intel/19.0.5.281). Here is where the failure is. Basically, all of the static_asserts are failing. Kitware is working on it, I just wanted to document it.
arena.h is found in: .../ThirdParty/protobuf/vtkprotobuf/src/google/protobuf/
static_assert(
InternalHelper<T>::is_arena_constructable::value,
"CreateMessage can only construct types that are ArenaConstructable");
