title: Angular Library copy assets not working ng-packagr
body: <p>I am creating an angular library which will allow us to reuse a lot of filter components that we currently use (customer search, employee search, etc).  In my library, I am importing scss files into my component's scss file (in this case telerik). The problem I am running into is view encapsulation.</p>
  
  <p>So how can I export a global stylesheet in the library that my applications can consume? I am needing this for testing locally and obviously production.</p>
  
  <p>I've tried ng-packagr "assets", but nothing seems to happen. Do I need to update my angular.json or somehow import the libraries assets scss in my app's styles.scss?</p>
  
  <p>This is my ng-package.json file if it helps.</p>
  
  <pre><code>{
    "$schema": "../../node_modules/ng-packagr/ng-package.schema.json",
    "dest": "../../dist/filters",
    "assets": [
      "assets"
    ],
    "lib": {
      "entryFile": "src/public-api.ts"
    }
  }
  </code></pre>
