title: OpenCV-2.1.0 and CMake2.8.2
body: <p>When I try to press the <code>Configure</code> button at <code>CMake 2.8.2</code> after adding:</p>
  
  <p>C:\Program Files\OpenCV-2.1.0 to <code>Where is the source code:</code></p>
  
  <p>And,</p>
  
  <p>C:\Program Files\OpenCV-2.1.0\build to <code>Where to build the binaries:</code></p>
  
  <p>I get an error message stating the following:</p>
  
  <p><code>Error in configuration process, project files may be invalid</code></p>
  
  <p>I can also see the following messages:</p>
  
  <p><code>CMakeError: Unable to open cache file for save. C:\Program Files\OpenCV-2.1.0\build\CMakeCache.txt</code></p>
  
  <p><code>CMake Error: : System Error: Permission denied</code></p>
  
  <p><code>CMake Error: : System Error: Permission denied</code></p>
  
  <p>Provided that I don't have <code>CMakeCache.txt</code> inside the <code>build</code> directory.</p>
  
  <p>How can I solve this issue?</p>
  
  <p>Thanks.</p>
