Is this really minimal ?

I would suspect the following might already be enough ?

----------------------

find_package(KDE4 REQUIRED)

set(failure_LIB_SRCS dummy.cpp)

kde4_add_library(failure SHARED ${failure_LIB_SRCS})
target_link_libraries(failure ${KDE4_KIO_LIBS})

----------------------

Can you please try ?
I guess it's caused by target_link_libraries().
If there are no errors, add the set_target_properties() call again.
I think the install() should be innocent.

Can you get a backtrace from the point where the error message is printed ?
It is in Source/cmTarget.cxxm void cmTarget::GetLibraryNamesInternal()
