I was thinking about this myself. I believe it's part of the LLVM getting started page, which we link initially. On the other hand, it might be good to point out that you need libcxx on macOS. I'll leave the decision up to you.

Do you think it's worth explaining here that we can generate the IDE workspace for standalone LLDB and have the dependencies in a provided Ninja build-tree?

Yep, definitely! I was going to ask you to complete this section as you've been working on this.

Sounds good!
