KF5 include problems on the build.kde.org?

[Friedrich W. H. Kossebau]

Hi,

I am currently struggling to have the KF5 port of Okteta not only build 
locally (what it does fine), but also on KDE's build server:
could anybody hint to me why on the build server the file KLocalizedString is 
not found for include on building of the static lib kastencoretestio:

>From http://build.kde.org/job/okteta_master_qt5/8/console :

--- 8< ---
13:23:17 
/srv/jenkins/workspace/okteta_master_qt5/libs/kasten/core/tests/testdocumentfileloadthread.cpp:28:28: 
fatal error: KLocalizedString: No such file or directory
--- 8< ---

libs/kasten/core/tests/CMakeLists.txt has this:
--- 8< ---
set( kastencoretestio_LIB_SRCS
  testdocumentfileloadthread.cpp
  [...]
)

add_library( kastencoretestio  STATIC ${kastencoretestio_LIB_SRCS} )
target_link_libraries( kastencoretestio LINK_PUBLIC Qt5::Core )
target_link_libraries( kastencoretestio LINK_PRIVATE KF5::I18n KF5::CoreAddons 
Qt5::Core )
--- 8< ---


Locally I see no problem with the problem, and the setup seems proper:
The file KLocalizedString is inside the KI18n include dir as expected, and 
also the KDE4 variant is outside the used includes dirs.

$ ls /home/koder/System/kf5/include/KF5/KI18n
ki18n_export.h  KLocalizedString  klocalizedstring.h  KuitMarkup  kuitmarkup.h  
KuitSetup  kuitsetup.h
$ find /usr/include/ -name KLocalizedString
/usr/include/KDE/KLocalizedString


$ VERBOSE=1 make

It is especially strange because with other libs that also include 
KLocalizedString there is no problem before in the same build. E.g. oktetacore 
has in core/CMakeLists.txt:
--- 8< ---
add_library( ${oktetacore_LIB} SHARED ${oktetacore_LIB_OBJS} )
target_link_libraries( ${oktetacore_LIB} LINK_PUBLIC Qt5::Core )
target_link_libraries( ${oktetacore_LIB} LINK_PRIVATE
  KF5::I18n
  KF5::KDE4Support
  KF5::Codecs   #needed for codecs
)
--- 8< ---

and you can see in the log
--- 8< ---
13:23:20 [ 24%] Built target oktetacore
--- 8< ---


What could be different on the buildserver? What is wrong in the 
CMakeLists.txt perhaps?
And does Okteta (branch: kf5-port) build for you locally?

Cheers
