How to build single independent Cesium.js and use it in html in old fashioned way

I need to add the cesium and ol-cesium libs to an old project that use it's own js minifier and and all js files should address statically without dynamic load of any other js.
I try cesium old fashioned example but it load other cesium dependencies dynamically and I need a single file (un-minified one) of Cesium.js. If there is a way to build that single file that load statically please show me to do that.

When you download CesiumJS (, under the Apps folder you’ll find a HelloWorld.html. That’s a simple plain HTML that loads the combined Cesium.js file along with some CSS and images for the widgets.

Is that what you’re looking for?
