title: How to include and install local dependencies in setup.py in Python?
body: <p>I am creating a <strong>setup.py</strong> to distribute my application.
  This application has a number of dependencies which can be installed via pip, it also has some custom dependencies which can not be installed from PyPI.</p>
  
  <p>So, I have created a <code>custom_package_0.1.whl</code> which will be included into the distribution and must be installed as a dependency after <strong>setup.py</strong> installs everything from <code>install_requires</code>.</p>
  
  <p>Imagine the following app structure:</p>
  
  <pre><code>my_app/
      win_deps/custom_package_0.1.whl
      my_app/
          __init__.py
          main.py
          setup.py
          setup.cfg
  </code></pre>
  
  <p>How do I do that? </p>
