title: WARNING: makefile.in seems to ignore the --datarootdir setting
body: <p>While trying to configure WxWidgets 2.9.1 on Windows XP (32 bit) the configure script ended with this:</p>
  
  <pre><code>...
  config.status: creating Makefile
  config.status: WARNING: Makefile.in seems to ignore the --datarootdir setting
  config.status: error: cannot find input file: contrib/Makefile.in
  configure: error: ./configure failed for src/tiff
  </code></pre>
  
  <p>I made sure that mentioned Makefile.in is where it should be. I use MinGW32 for make.</p>
  
  <p>I found <a href="https://answers.launchpad.net/ubuntu/+question/46882" rel="nofollow">this</a>, I tried to translate it somehow to my situation (from Ubuntu to Windows), but it still returns the same error.</p>
  
  <p>How should I solve it?</p>
