"More build options" - that's basically what I mean. If we provide them, it 
means work for somebody to implement them (probably me).
If we don't, they have to hack them up in some way.
e.g. the kate library in kdelibs.
If it's built as one we can simply do:

target_link_libraries(katepart .... kdecore)

and it will link to the correct libkdecore.so, since kdecore is a target in 
the same project.
If katepart would be built separately, we have to do something else.
We need to have a
somewhere (but which would find only part of kdelibs, i.e. without katepart, 
which will be somewhat strange), and then we could use either

target_link_libraries(katepart .... kdecore)
in KDE 4.2-style, since then kdecore would be an "imported" target with all 
properties set up, or
target_link_libraries(katepart .... ${KDE4_KDECORE_LIBS})
where all that is covered by the variable. 
Doing this consistently requires some work, and providing such a build option 
is not completely trivial.
I.e. if we provide it, it says "KDE wants the distros to ship such packages", 
if we don't, it means "KDE doesn't want to distros to ship such packages".
From that POV KDE decides to some part what distros will ship, and I doubt 
that packagers are "perfectly" capable of doing this without support from us.
