Thanks for making this pull request! Could you move point 3 to the first position? It is always good to begin with updating you system before doing anything else (especially on WSL it seems).

I am still not sure about why libopenmpi-dev is needed, and that most likely has more to do with the detection through cmake. But that would require a bit more investigation, so for now I think it is fine to just recommend to install it.

Done!
