Now a serious question: what is irritating about these warnings ?

They state exactly what happens.

They happen if you simply do
find_package(LibKolab)

If you do instead
find_package(LibKolab NO_MODULE)

they will be slightly different, since in this case cmake doesn't have to guess 
whether you are looking for a FindLibKolab.cmake or a LibKolabConfig.cmake.
CMake will still tell you that it didn't find that file and what to do about it.

If you want to get the short messages you are used to.
add a simply FindLibKolab.cmake, which contains more or less

find_package(LibKolab NO_MODULE QUIET)
find_package_handle_standard_args(LibKolab  DEFAULT_MSG  LibKolab_DIR)

Or, with cmake >= 2.8.3 (which we do not require yet):
find_package_handle_standard_args(NAME LibKolab  CONFIG_MODE)
