Sorry, I should have chosen my words more carefully. I do understand
the cause of the breakage. I recently posted a question to the mailing
list how to work around broken find modules. Maybe Ryan Pavlik's answer
http://www.mail-archive.com/cmake@cmake.org/msg32351.html could be
helpful for KDE as well. It doesn't solve the current breakage, though,
because it needs modifications to the KDE CMake modules.

Best regards,
Marcel Loose.
