docs: Need to find any pre-existing vext contained in dependent packages
          and install them
  
          example:
  
          you create a setup.py with install_requires["vext.gi"]:
  
          - vext.gi gets installed using bdist_egg
          - vext itself is now called with bdist_egg and we end up here
  
          Vext now needs to find and install .vext files in vext.gi
          [or any other files that depend on vext]
