I hope it doesn't come to this.
If there are KDEPIM4 apps that are cause data loss or *really suck*
then we I think we simply shouldn't build them in the toplevel CMakeLists.txt.

Which reminds me of an idea I had...  we could have stuff like this in
our top-level CMakeLists.txt files to exclude apps that aren't "KDE4.0-ready"

if (NOT ${KDE_ENABLE_FINAL})
add_subdirectory(appfoo)
endif(NOT ${KDE_ENABLE_FINAL})

then appfoo won't be built if the distro packagesuse 'cmake -DKDE_ENABLE_FINAL'.

I guess what I'm really saying/asking: we need to put some responsibility on
the distro packagers to help us make a KDE 4.0 desktop work.
