[yocto] static libraries missing from sdk

[Mircea Gliga]

Hi


 > I am not sure it makes sense to build and add both the static and 
dynamic libs to an SDK.
The idea is that I want everything that is needed to build the app in 
the SDK and I don't want to individually specify what goes in because 
it's error prone and you can forget something.
Some pkgs could have dynamic libs other could have static libs ...

See below further comments.
Thanks for your help!

That's what I've been missing... I need to add the empty main pkg in the 
image and then the static library ends up in the SDK - because the SDK 
it's build upon the image...
It's not a perfect scenario... First you have to create the empty main 
pkg using ALLOW_EMPTY then install the empty pkg in the image...
