title: Issue with ItkVtkGlue
body: <p>I'm trying to run this example: <a href="http://www.itk.org/Wiki/ITK/Examples/IO/ImageFileReader" rel="nofollow">http://www.itk.org/Wiki/ITK/Examples/IO/ImageFileReader</a></p>
  
  <p>But, get the following when I "configure" in CMake:</p>
  
  <pre><code>CMake Error at CMakeLists.txt:11 (find_package):
  By not providing "FindItkVtkGlue.cmake" in CMAKE_MODULE_PATH this project
  has asked CMake to find a package configuration file provided by
  "ItkVtkGlue", but CMake did not find one.
  
  Could not find a package configuration file provided by "ItkVtkGlue" with
  any of the following names:
  
  ItkVtkGlueConfig.cmake
  itkvtkglue-config.cmake
  
  Add the installation prefix of "ItkVtkGlue" to CMAKE_PREFIX_PATH or set
  "ItkVtkGlue_DIR" to a directory containing one of the above files. If
  "ItkVtkGlue" provides a separate development package or SDK, be sure it has
  been installed.
  </code></pre>
  
  <p>It seems I need "ItkVtkGlue"? Where can I download it? And, what should I do to combine it with the program?</p>
