title: OpenCvSharp.CvConst class missing?
body: <p>I am working on a project with OpenCvSharp.</p>
  
  <p>I want to port <a href="https://docs.opencv.org/2.4/modules/calib3d/doc/camera_calibration_and_3d_reconstruction.html#findchessboardcorners" rel="nofollow noreferrer">this</a> script to C#:</p>
  
  <pre class="lang-cpp prettyprint-override"><code>bool patternfound = findChessboardCorners(gray, patternsize, corners,
          CALIB_CB_ADAPTIVE_THRESH + CALIB_CB_NORMALIZE_IMAGE
          + CALIB_CB_FAST_CHECK);
  
  if(patternfound)
    cornerSubPix(gray, corners, Size(11, 11), Size(-1, -1),
      TermCriteria(CV_TERMCRIT_EPS + CV_TERMCRIT_ITER, 30, 0.1));
  
  drawChessboardCorners(img, patternsize, Mat(corners), patternfound);
  </code></pre>
  
  <p>and I got everything to work, except for the <code>CV_TERMCRIT_EPS + CV_TERMCRIT_ITER</code> etc.
  I just can't find theese constants! I looked for them in every package I could think of and searched the entire assembly tree for them with no success.</p>
  
  <p>In the <a href="https://github.com/shimat/opencvsharp_2410/search?q=cvconst&amp;unscoped_q=cvconst" rel="nofollow noreferrer">source code</a> and the <a href="https://shimat.github.io/opencvsharp_2410/html/f6bbfd34-a465-73ad-fa49-3f6eee2aeec2.htm" rel="nofollow noreferrer">documentation</a>, <code>CvConst</code> is used but I can't find that class!</p>
  
  <p>I tried installing various NuGet Packages and ended up with the following:</p>
  
  <ul>
  <li>OpenCvSharp4</li>
  <li>OpenCvSharp4.runtime.win</li>
  <li>OpenCvSharp4.Windows</li>
  </ul>
  
  <p>(the first ones were installed by the last one)</p>
  
  <p>So <strong>where is OpenCvSharp.CvConst?</strong></p>
