Shimano 8sp trigger with 105(5700 or 5800) rear derailleur

So I'm building a budget 1x bike and have an 8 speed Shimano (Alivio?) trigger shifter and a 5700 long cage 105 and a 5800 short cage 105 derailleur I want to use. Are either of these compatible with the shifter? I've seen alternative cable routing on other builds that accommodate for the difference in cable pull. What are my options other than buying a new derailleur?

I'm sorry, you're right about that.
