[vtkusers] Linking to VTK static libraries on Windows

[Dave Partyka]

The USE_SYSTEM flags are meant for linking in system installed/externally
built versions of these libraries. On Linux/Mac you can easily install
'development' versions of these libraries using their respective package
managers and then configure the USE_SYSTEM flags to point to those libraries
instead. On Windows you would have to build those libraries by hand so don't
worry about the USE_SYSTEM options.

Anyway, I am not entirely sure if link order matters but you might try
putting vtkCommon and vtkFiltering before vtkIO as nearly everything in VTK
depends on vtkCommon/vtkFiltering.
