How do you enable the Raspberry Pi camera in Yocto

Question

I'm trying to get my Raspberry Pi camera to work with my Yocto image. I found here that I need to add the following line:

VIDEO_CAMERA = "1"

I added it to my meta's recipes-core/images/example-image.bb but still when I try to take a picture I get:

root@user:~# raspistill -o testshot.jpg
mmal: mmal_vc_component_create: failed to create component 'vc.ril.camera' (1:ENOMEM)
mmal: mmal_component_create_core: could not create component 'vc.ril.camera' (1)
mmal: Failed to create camera component
mmal: main: Failed to create camera component
mmal: Camera is not enabled in this build. Try running "sudo raspi-config" and ensure that "camera" has been enabled

So it seems like it's not enabled. And raspi-config seems to be only available on Raspbian, in fact it's not recognised as a command.

Am I missing anything else? I can't find much info out there and I'm still new to Yocto.
