title: Installing Python and openCV during macOS Application Installer
body: <p>I am building a desktop application using <code>Swift 5</code>. Its an image processing and manipulation application. For this purpose, I need to use <code>Python3.7</code> with <code>OpenCV</code>.</p>
  <p>The project is complete. I downloaded <code>Python3.7</code> and pip installed openCV on my terminal. And executed the commands using <code>PythonKit</code>.</p>
  <p>What needs to be when I ship the desktop application on my website. How would these dependencies be installed by the installer? What is the quickest way to download and install these dependencies during the mac OS installer phase?</p>
