This looks like a nice opportunity to add a bitbake-setup config into
meta-zephyr that would do these with a single command :)

[Sandeep]: Alex, I'm having hard time to use bitbake-setup, does 
bitbake-setup will clone and include dependency layers? For example 
meta-zephyr-core depends on meta-python (depends)-> meta-oe. If so we 
can simplify the instructions.

Take a look at https://git.openembedded.org/bitbake/tree/default-registry/configurations/poky-master.conf.json

You need to specify what repositories need to be cloned first, then,
separately, what layers need to be enabled. For example, there's one
entry for cloning meta-yocto, and then from that repository two layers
are enabled in a build:

            "bb-layers":
["openembedded-core/meta","meta-yocto/meta-yocto-bsp","meta-yocto/meta-poky"],

Something similar can be written for meta-zephyr dependencies.
