We want both these packages from the SoC specific layer and not the ones that are coming from meta-ivi. The reason being that the SoC vendor has done some modifications for hw acceleration and stuff like that. Since meta-ivi is having higher priority( Priority: 7) than the SoC specific layer(Priority : 6) , naturally these packages are provided by meta-ivi and not the Soc layer which we actually want.

Try moving the recipe to your layer (provided yours is of higher
priority). I often go with per project BSP layers that adjust the low
level pieces of the target, such as kernel configs etc., while
applications stay in application-only layer.

Another option that I see is to set BBMASK =
"meta-ivi/recipes-graphics/wayland/" in local.conf, but that's a bit
ugly, hence I'd say it's a temporary solution only.
