title: CMake GUI - set folder in windows ( VTK is not found)
body: <p>I'm trying to compile OpenCV on Windows 10 with all the modules (following <a href="http://building-and-installing-opencv-3-0-on-windows-7-64-bit/" rel="nofollow noreferrer">this tutorial</a>).</p>
  
  <p>This is the error I get after pressing "Configure":</p>
  
  <pre><code>VTK is not found. Please set -DVTK_DIR in CMake to VTK build directory,
  or to VTK install subdirectory with VTKConfig.cmake file
  </code></pre>
  
  <p>I've installed VTK 7 by the <code>msi</code> file.</p>
  
  <p>I tried to specify a library path but it didn't help (using the same method from <a href="http://cmake-gui-specify-library-path-for-windows" rel="nofollow noreferrer">here</a>), and also set an environment path for this.</p>
  
  <p>What else can I do to pass this error?</p>
