kconfig now also builds and installs as a separate library, and can be found 
via KF5:
find_package(KF5 MODULE .... kconfig)

or separately:

find_package(kconfig NO_MODULE)

Is it only me who would prefer CamelCase to alllowercase names ?
find_package(KConfig NO_MODULE)

P.S. current plasma-frameworks needs current kdelibs
