[yocto] Add custom user to custom group in bitbake recipe

[Parthiban Nallathambi]

Hello All,

I have created a custom group e.g "grp1" in my application recipe say 
"app.bb".

GROUPADD_PARAM_${PN} = "grp1"

I am trying to add my custom user e.g: "user1" to this group "grp1" in 
"space.bb".

USERADD_PARAM_${PN} = "-d ${localstatedir}/lib/space/ -s /bin/false -G 
grp1 -U user1"

The useradd command failed: "useradd: group 'grp1' does not exist". I 
have also tried adding DEPENDS_${PN} = "app" in space.bb, but it doesn't 
help.

How can I add my custom user to my custom group in bitbake recipe?
