Hi all

I working on a image recipe.

If I include the layer meta-raspberrypi layer  I'd like to include
recipes-code/images/rpi-basic-image-bb.

While if i not include meta-raspberrypi layer I don't include
rpi-basic-image.

Or you can just safely ignore if the file does not exist (for Yocto,
which most likely means that the layer is not included).

You have two "include" mechanisms for non-class files:
* require
* include

"Require" requires the file to be there and fails otherwise while
"include" tries to include the file, if it's not there, it continues.
