Wow, what a mess ;-)
Don't know where to start.

FindKDE4Internal.cmake is a find-module, and cmake does not "search" those, it 
expects them to be either in its own share/cmake/Modules/ directory or in 
CMAKE_MODULE_PATH.
So it can't be found.
Probably you can run cmake -
DCMAKE_MODULE_PATH=/where/kf5/is/share/cmake/modules and it seems to work 
when.

Additionally, they search for find_path(KDE_MODULES_DIR NAMES KDE4Macros.cmake 
...)
which is included later on by FindKDE4Internal.cmake anyway.


Do they really need Win CE support ?

Then all the options are set manually...

OTOH, AFAIK currently at least I am not aware of what the official way of 
using the frameworks branch of kdelibs is.

Do we have an official way ?
