title: Compile OpenSceneGraph with Cmake under Windows
body: <p>I am trying to set up Openscenegraph 3.0.1 with Cmake. I read different blog posts but it doesn't work.</p>
  
  <p>I set up the paths, click compile and selected VS11 (because I have VS 2012) and use native compiler.</p>
  
  <p>Then I directly get this error:</p>
  
  <pre><code>CMake Error at C:/Program Files (x86)/CMake 2.8/share/cmake-2.8/Modules  CMakeCInformation.cmake:37 (get_filename_component):
  get_filename_component called with incorrect number of arguments
  Call Stack (most recent call first):
  CMakeLists.txt:3 (PROJECT)
  
  
  CMake Error: Internal CMake error, TryCompile configure of cmake failed
  Looking for include file pthread.h - not found
  </code></pre>
  
  <p>Also, more errors with the same stack trace occur. Also also could paste them here if you wish.</p>
  
  <p>Afterwards, CMake tells me "Error in configuration process, project files may be invalid"</p>
