Actually I found out that I did it wrong :) I added the
LINK_INTERFACE_LIBRARIES in the first target_link_libraries where all the
needed libs for kdevplatforminterfaces are listed. So "all hell broke
loose" and nothing linked anymore. After introducing a new separate line
for that it looked a lot better.

So basically I just need to sit down and check which libs need to be in
LINK_INTERFACE_LIBRARIES and then adjust the cmake-files accordingly.

Am I right that any symbol/class used in external API means the library
providing that symbol should be in the LINK_INTERFACE_LIBRARIES?
