This is the suspicious bit... If you look at the recipe, you'll notice
it's re-defining the PACKAGES variable. Then, it's not generating a
package called 'cppzmq', but only one named 'cppzmq-dev'. That said,
I'm not sure why you'd want to add a package which only provides
development headers to your target image...
