title: How can I add the CopyWebpackPlugin to create-react-app without ejecting?
body: <p>I am building a react application and <strong>I want to copy all image files from the source destination to the build destination</strong>. I am following some tutorials and so far managed to use <code>react-app-wired</code> and the <code>CopyWebpackPlugin</code></p>
  
  <p>I am getting no errors and no files are being copied.</p>
  
  <p>This is my <code>config-overrides.js</code></p>
  
  <pre><code>const CopyWebpackPlugin = require('copy-webpack-plugin');
  
  module.exports = function override(config, env) {
     if (!config.plugins) {
      config.plugins = [];
    }
    config.plugins.push(
      new CopyWebpackPlugin(
      [
        {
          from: 'src/images',
          to: 'public/images'
        }
      ])
    );
    return config;
  };
