title: Building 32bit libraries opencv
body: <p>I recently downloaded and built opencv in my 64-bit Windows machine using <code>cmake</code>. All the binaries are included in the <code>install</code> folder and it contains only the folders as shown below:

  <p>I don't know how to config cmake to produce binaries for x86. I'm asking this, because I'm using <strong>Qt Creator 32bit with MinGW</strong> and I'm getting problems while linking and compiling the code. What's the proper way to do the build? I'm using <code>mingw</code> compiler suite.</p>
  
  <p><strong>Note: The downloaded package contains the pre-built binaries for <code>x86</code> but there are none for MinGW, but only for Visual Studio.</strong></p>
