Please refer to the previous vUDS[1], there's been a lot of talk about this
there (look for either click or SDK). It's a bit of the other way around[2]
(at least for QML).

What I'm doing is using a mod from pull-lp-source[3] to grab the so, strip
it out and use it. For packages that are a bit more complex I added a
CLICK_MODE to the cmake options and have a debian packaging wrapper that
just builds the click package (build depends for shared libs carefully
don't leave the constrained list).

The debian wrapper is until click building is added in, which should build
(cross compile) out of a chroot that has everything you need and available
for development from the base touch image.
