How does metadata include in an image recipe work?



I have two images recipes, one is included in another image recipe:

$ ls recipes-core/images

$ cat recipes-core/images/


My understanding that the metadata "include" is to include all image
files defined in the included recipe as well, but when I run bitbake
ex-image2, it only built ex-image2 image, it did not built images
defined in

What could I be missing here? How could I build an image to include
all image files included in another

Thank you.

Kind regards,
