This is an issue which is not yet solved perfectly in cmake, the developers 
are currently disussing a good solution.

For kdepimlib:

There should also be a
find_package(KDE4)

Once this succeeded, the CMAKE_MODULE_PATH (where cmake searches for modules) 
should be set so that $top/share/apps/cmake/modules/ is part of it.
Then KDEPIMlib should be found automatically.
I'll have a closer look at it in the next days.
