title: PocketSphinx install can't find swig.exe
body: <p>I have searched all over the web and especially have gone through all the questions regarding this here on Stackoverflow.</p>
  
  <p>I am using the following command to install it "pip install pocketsphinx"</p>
  
  <p>I have windows x64,
  I have not set any environmental paths regarding Swig.</p>
  
  <p>Also I've downloaded Swig zip file and extracted it into my downloads folder, searched through it and there is no "swig.exe" file.</p>
  
  <p>Below you can see the error/log from the command prompt.</p>
