Changes in the buildsystem from KDE 4.0/4.1 to KDE 4.2
Starting with KDE 4.0.0 source compatibility is guaranteed, this
doesn't apply only to the C++ sources, but also to the
- The reduced link interface, details see below. It may be possible that an application which linked against KDE 4.0/4.1 now fails due to unresolved symbols. In this case the libraries which provide these symbols have to be added to the TARGET_LINK_LIBRARIES() calls. This happens only if symbols are used but the library is not linked again. This can be considered a bug in the cmake files of these applications. Applications which explicitely link against all libraries they use will build successfully with KDE 4.2.
Required CMake Version
At least version 2.6.2 of CMake is required now. With KDE 4.0 and 4.1 version 2.4.5 was required.
KDE4_ALWAYS_USE_FULL_RPATH doesn't exist anymore.
