How to use dub with ldc

[tobi via Digitalmars-d-learn]

Hi, I'm new to D and I would like to get the dlang-tour onto my 
local machine.

As far as I know, on my Pinebook Pro using aarm64 architecture, I 
must use the LDC compiler. The dlang-tour readme says to run `dub 
run dlang-tour -- --lang-dir .` which will run `rdmd` commands.

Is there a way to tell dub to work with ldc instead?

Thanks for your help!
