[Star Wars] Where did the materials for the Death Star come from?

The DS (and DSII) are massive. They’re mini moon sized things made mostly out of durasteel. Where did all of that durasteel come from, though?

The Death Stars were killing planets before the lasers were even operational. Ahsoka ends up on a planetary body that is being farmed to death to support the nutritional demands of the Empire's workforce - and possibly the Death Star crew. The people (labor) of Geonosis were exterminated by the Empire. Ezra's home world is being mined into a wasteland for metals. Jedha is in severe decline as the Empire strips all the kyber from it. The resources for the Death Stars came from other planets and moons in the Galaxy. It's akin to the excavation of lands from one country to extend the landmass of another.
