I also saw that warning with this example (there's nothing in this example 
about a MONOLITHIC install):

cmake_minimum_required(VERSION 2.8)
project(hello)
install(CODE "message(installing...)" COMPONENT Hello)
set(CPACK_COMPONENTS_ALL Hello)
set(CPACK_COMPONENTS_ALL_IN_ONE_PACKAGE 1)
set(CPACK_ARCHIVE_COMPONENT_INSTALL 1)
include(CPack)

$ cpack -G TGZ

Why is it a warning if no groups are defined?  Is it because one should use 
groups?
However, I can suppress that warning with 
set(CPACK_COMPONENTS_IGNORE_GROUPS 1)
