title: Install mixture of extension module. pure python module and shared libraries with distutils
body: <p>I am using cython for building an extension module. The module depends on an external shared library, which is found when the module is built. Further I have some pure Python modules in the same directory. </p>
  
  <p>Can anybody give me an example setup.py for this task ? I have problems getting the extension module, the pure python module and the shared lib in the same directory when calling "python setup.py install".</p>
