Hi,

I am trying to build cppzmq through a Yocto (Rocko) generated eSDK. The search 
function does not return anything, despite the recipe being available through 
local recipe:

martin@dell:~/gomspace_sdk$ ls 
layers/meta-openembedded/meta-oe/recipes-connectivity/zeromq/
cppzmq_git.bb  files  zeromq_4.1.6.bb

I assume this is expected since it does not come prebuilt as part of the eSDK - 
is this correct understood? 

Fortunately, 'devtool modify/build/package' generates the package - 
unfortunately it is not included in the subsequent image generation:

martin@dell:~/gomspace_sdk$ devtool package cppzmq

Inspecting the manifest file confirms that the package is not installed - any 
idea why not? I also tried installing though sdk-install:

martin@dell:~/gomspace_sdk$ devtool sdk-install -s cppzmq

Which also does not pick up the package upon image building:

What am I missing here?
