The problem is that bitbake runs recipes, not packages.  So in order to
get the package 'packagegroup-custom-tools', you have to build your main
recipe which will also build 'packagegroup-custom-apps'

I've run across this myself and what I did was to split my package groups
(then called tasks) into separate recipes.
