Ok, but if I specify - for instance - "/path/foo/libbar.a" 
(TARGET_LINK_LIBRARIES), cmake transforms it to "-L/path/foo -lbar" at 
the link line ...

Thank you, this works as long as there is at least one source file given 
here: ADD_EXECUTABLE(exe sourefile1 ...). But in my project there are no 
additional sourcefiles. "exe" consists of the static libs built in the 
subdirectories only. And I do not want to use a "dummy" sourcefile. What 
can I do?

Thanks,
Christian
