title: OpenCV:NetBeans:undefined reference to cvCreateSubdivDelaunay2D
body: <p>I am using NetBeans 7.0.1 to develop C++ applications using OpenCV 2.4.0 on Ubuntu 11.10.  When I try to build the application I get the following link error messages.</p>
  
  <pre><code>undefined reference to `cvCreateSubdivDelaunay2D(CvRect, CvMemStorage*)'
  undefined reference to `cvSubdivDelaunay2DInsert(CvSubdiv2D*, cv::Point_&lt;int&gt;)'
