Fix Issue #300 reduce CDash warnings and errors
Created by: williamfgc
Remove cdash warnings for unused variables, type cast (including HDF5 char vs. int8) and virtual functions overloads.
During the maintenance period on Monday, 14 Oct 2024, all new projects will no longer create a container registry as part of the project area. Already existing projects will be unaffected at this time. Instead, users should utilize the official ORNL container registries at camden.ornl.gov (internal/moderate) and savannah.ornl.gov (external/low). Please see ORNL Today article for more info.
