The KActivitiesConfig.cmake file is probably looking for things
relative to its own location but somehow it has been included
as "/lib/cmake/..." without a drive letter so paths computed
relative to its own location also do not have a drive letter.

Something is handing the find_package call a search path without
a drive letter.  Read the find_package docs here:


to see the list of places it gets search paths.  Use message()
to print each one out just before the call to see which one has
the missing drive letter.
