That superbuild directory doesn't seem to work for me. Although I run cmake 
on it with cmake master, it seems to try to use cmake 2.8.9 from my distro 
when building the subprojects.

I reproduced the problem with a build of kcoreaddons alone.

As I wrote elsewhere in this thread, the plan going forward is to have cmake 
populate the INTERFACE_INCLUDE_DIRECTORIES with the INSTALL_INTERFACE. 

Until that is done we can either add code to do that ourselves (and remove 
it later), or simply use include_directories() where you need it. I've 
pushed a commit doing the former for kdeqt5staging, so tier1 libs which 
depend on that should work in your superbuild again.

Thanks,

Steve.
