Best way of importing maplab into an IDE?

[Emilio-90]

So I want to start wotking on maplab, but since it is a very big project I want to ask what is the best way to import it into an IDE? Especially since it uses catkin_tools, therefore there is not a parent CMakeList vor the whole project?.

I saw this post: https://github.com/ethz-asl/maplab/issues/14 from 4years ago and read the Import Maplab to Eclipse wiki page.
Is there an updated approach, especially for (18.04 or 20.04)? Why does the Eclipse approach use llvm/clang instead of gcc? And do you know which of the newer clang version is compatible with maplab?

Thank you!
