Comment (by nicos@…):

 I'll make the commit later today. For reference, when looking at the two
 folders, I found at least the files below which are installed both by
 cmake and kdelibs4, usually with a difference in capitals.

 FindAlsa.cmake[[BR]]
 FindFlex.cmake[[BR]]
 FindGettext.cmake[[BR]]
 FindLibLZMA.cmake[[BR]]
 FindLibXslt.cmake[[BR]]
 FindRUBY.cmake

 I did not look up if they are identical or not, but several of them should
 be working, as they should be used by low-level ports during the configure
 stage.
