   Two ways. 

  1.- If you own Leica, and can hoof the outrageous price for the 
      swing-away polarizer, you can wysiwyg.

  2.- Otherwise, you will note most (all?) polarizers have a dot
      on the perimeter. In the ones I own, if you align that dot
      in the closet direction of the sun WRT lens axis, you will get
      maximum available polarization (remember, this effect varies
      with the angles of the surfaces of objects, so this "dot"
      method works best for the sky, and in general.
