How to include assets from node_modules in angular cli project

This does now exist!

Fix #3555

To use it, update your .angular-cli.json file like so…

Angular version 2-5:

"assets": [
  "assets",
  { "glob": "**/*", "input": "../node_modules/<external library>/assets/", "output": "./assets/" }
]

Angular version >= 6:

"assets": [
  "src/favicon.ico",
  "src/assets",
  {
    "glob": "**/*",
    "input": "./node_modules/<your-node-module>/<possibly-subfolders>/",
    "output": "./assets/"
  },
