My project is already using this style:

   set(CPACK_COMPONENTS_ALL runtime development mstool)

i.e. all components are already defined. All that's missing is the 
declaration of their (inter-)dependencies.

Are you suggesting I should *not* use CPACK_COMPONENTS_ALL, but instead 
call `cpack_add_component()` instead ?

Thanks,


Stefan
