By default, dey-image-qt doesn’t have WebKit support and dey-image-webkit doesn’t have Qt support. However, it’s possible to build images with both elements. To do so, you can manually append packagegroup-dey-webkit to the image in your project’s conf/local.conf file:

conf/local.conf
IMAGE_INSTALL_append = " packagegroup-dey-webkit"

After doing this, building dey-image-qt will create an image that contains both Qt and WebKit support.
