How to insert css file into stylus?

Question

css

There is a style.style file

@import './styles/reset.styl';
@import './styles/grid.styl';
@import './scripts/vendor/fontawesome/css/font-awesome.min.css';
@import './styles/main.styl';

Well, everything seems to be clear, first we connect all sorts of resets and normalizations, grids and bootstraps, then the styles of third-party libraries, in my case it is the fontawesome icon font, and at the end all the other styles.
The problem is that when compiling, all stylus files are copied to this file, and the line

@import './scripts/vendor/fontawesome/css/font-awesome.min.css';

it will remain so and, accordingly, import connection is possible only at the beginning, but in the middle of the css file it will not work and font-awesome.min.css will not be connected.
Is it possible to do in stylus that when compiling to css, lines like

@import './scripts/vendor/fontawesome/css/font-awesome.min.css';

inserted css from a file, and did not remain an import?

Answer 1

Understood. When compiling, just specify 'include css': true

.pipe(stylus({
      'include css': true
}))

Answer 2

First you collect .styl into css file(s), then using another plugin, glue all css into one.
