The easiest way I know is to use CPACK_COMPONENTS_ALL, which is what I
use to package subsets of my components.

I don't currently use grouping, but if I would, I would create
something like an add_component_to_group(compname, groupname)
function, that you can call for every component when you first define
it (or add a GROUP parameter it to my define_package_component()
function). In addition to setting
PACK_COMPONENT_${compname_uppercase}_GROUP to ${groupname}, it should
append ${compname} to a (global) package_group_${groupname}_components
list variable. Then populate the CPACK_COMPONENTS_ALL list by
iterating over your list of required groups, and for each group name,
append ${package_group_${groupname}_components}.

Hope that gives you some ideas to start from,
