[vtkusers] building VTK 7.1.0 on MSYS2: undefined references

[David Lonie]

According to Common/DataModel/module.cmake, vtkCommonDataModel already has
a dependency on vtkCommonCore inside of VTK. Everything should be linked
already. Hmm.

It's likely that the mingw support needs some love. I don't think we have
any customers that rely on it at the moment, but maybe someone can pick it
up.
