AddHelp option to Initialize should add --help argument (!2895) · Merge requests · VTK / VTK-m

When you used the AddHelp option to Initialize, it added a --vtkm-help option and -h, but not --help, which was weird. It also avoided adding --vtkm-help when AddHelp was not used, but did print out a usage statement under other circumstances.

This changes the behavior to add --vtkm-help, --help, and -h when AddHelp is on and only --vtkm-help when it is off.
