Commit patch from Alex
(He didn't have time to make it yesterday and will able to commit it next thursday)
This patch clean up some :
target_link_libraries(kfoo kdeinit_kfoo) which is already done in kde4_add_kdeinit_executable()
macro 	and use "INSTALL_TARGETS_DEFAULT_ARGS" in other place.
I tested all compile file, all works fine but if there is a pb send me a mail.
