So I found the Flags causing the problem:

`/wd4702 /wd4512 /wd4510 /wd4503 `

These are not passed into `-Xcompiler` as they should be.  
Looking at the `Accelerators\Vtkm\CMakeLists.txt` this seems to be supposed to specifically do that:

```auto
if (MSVC)
  set(msvc_warning_flags
    # Generates numerous false positives with template code about unreachable
    # code
    /wd4702
    # Generates numerous warning that implicit assignment operators can't be
    # constructed. This is understood and we don't care.
    /wd4512
    # Generates numerous warning that implicit constructors can't be
    # constructed. This is understood and we don't care.
    /wd4510
    # Generates warnings when decorated names are over 4096 characters
    # This compiler warning is deprecated and no longer occurs with VS2017+.
    # So we suppress for VS2015
    /wd4503
    )
  set(vtkm_msvc_flags)
  foreach (msvc_warning_flag IN LISTS msvc_warning_flags)
    if (TARGET vtkm::cuda)
      list(APPEND vtkm_msvc_flags
        $<$<COMPILE_LANGUAGE:CUDA>:-Xcompiler=${msvc_warning_flag},${msvc_warning_flag}>)
    else ()
      list(APPEND vtkm_msvc_flags
        ${msvc_warning_flag})
    endif ()
  endforeach ()
  vtk_module_compile_options(VTK::AcceleratorsVTKm
    PRIVATE
      ${msvc_warning_flags})
endif ()

```

I’ve tried to fiddle around with this but didn’t seem to manage anything, any suggestions? I see this was a issue on here before:
