Why do fonts stack in the root of dist/name_project?

Question

Angular

Directory structure

In the file:
src/assets/fonts/fonts.css I include
fonts:

@font-face {
  font-family: 'SF UI Text';
  src: url('SanFrancisco/SFUIText-HeavyItalic.eot');
  src: local('SF UI Text Heavy Italic'), local('SFUIText-HeavyItalic'),
  url('SanFrancisco/SFUIText-HeavyItalic.eot?#iefix') format('embedded-opentype'),
  url('SanFrancisco/SFUIText-HeavyItalic.woff') format('woff'),
  url('SanFrancisco/SFUIText-HeavyItalic.ttf') format('truetype');
  font-weight: 300;
  font-style: italic;
}

I run ng build
, everything is going to be OK, only all fonts are put in the
dist/angular-dashboard folder
in the root:

how to build so that the font files are in dist/angular-dashboard/assets/fonts?
