title: cmake built a 32 bit project in my 64 bit windows
body: <p>I'm using a cmake file(someone else wrote it) to build a project. I looked at the CMakeLists and saw he used</p>
  
  <blockquote>
    <p>if( CMAKE_SIZEOF_VOID_P EQUAL 8 )</p>
  </blockquote>
  
  <p>to detect if the system is 64 bit. I'm using 64 bit windows 8 and it should be built into a 64 bit project. Why do I end up having a 32 bit project? Is there any other thing I should do? </p>
