Changes in the buildsystem from KDE 4.4 to KDE 4.5

Starting with KDE 4.5, CMake >= 2.6.4 is required.

Incompatible Changes

FindQt4.cmake: Imported Targets for the libraries

Other Changes

Required CMake version

Starting with KDE 4.5, CMake >= 2.6.4 is required (KDE 4.2 to 4.4 required 2.6.2).

Commit Policy for kdelibs/cmake/modules/

The commit policy introduced during the 4.3 development cycle is still active and must be followed.

Support for QtDeclarative

Support for the new QtDeclarative module has been added to FindQt4.cmake. To use it, you can use the new variables QT_QTDECLARATIVE_LIBRARY, QT_QTDECLARATIVE_INCLUDE_DIR, QT_QTDECLARATIVE_FOUND and QT_USE_QTDECLARATIVE.

New libraries: kemoticons, kidletime, kcmutils and kprintutils

With KDE 4.5 3 four new libraries were added to kdelibs: the kemoticons library, the kidletime library, the kcmutils library and the kprintutils library. These libraries come with their associated variables. So if you want to link against these libraries, use ${KDE4_KEMOTICONS_LIBS}, ${KDE4_KIDLETIME_LIBS}, ${KDE4_KCMUTILS_LIBS} and ${KDE4_KPRINTUTILS_LIBS} respectively. They don't require an additional include directory.

Improved RPATH settings

In the previous releases of KDE 4, the library installation directory was always added to the RPATH of libraries and executables. With KDE 4.5 this is now only done if the library installation directory is not one of the system default library directories. This means that e.g. /usr/lib is not added anymore to the RPATH.

Other minor changes

  • A cache variable KDE4_SERIALIZE_TOOL has been added. It is empty by default,

but you can set it to a tool to serialize resource-intensive commands in parallel builds.

  • Some improvements to make cross compiling KDE easier were committed to FindKDE4Internal.cmake, but we are still not ready for cross compiling.
  • The documentation was improved, e.g. the macro KDE4_ADD_APP_ICON() was undocumented before.

New Modules

Some completely new installed modules have been added during this cycle:

  • FindDBusMenuQt.cmake


Also added were FindDocBookXML.cmake and FindDocBookXSL.cmake, but both are used only internally inside kdelibs and both are not installed.
