Let's just start with a simple example for an application, let's name it, well, kFoo. The CMakeLists.txt below gives the project a name, so that the project files for KDevelop/XCode/MSVC will have a good name. It will then find the KDE 4 installation on the system and setup the required include directories. The list of source files will be put into a variable named mySources, which will be automoced and then used to build an executable from it. The executable and its desktop file will finally be installed.

project(kfoo)

find_package(KDE4 REQUIRED)

include_directories( ${KDE4_INCLUDES} )

set(mySources main.cpp mywidget.cpp mypart.cpp)

kde4_automoc( ${mySources} )

kde4_add_executable(kfoo ${mySources})

target_link_libraries(kfoo ${KDE4_KDEUI_LIBS} ${KDE4_KPARTS_LIBS} )

install_targets( /bin kfoo)
install_files( ${XDG_APPS_DIR} FILES kfoo.desktop)

Ok, and now for a full-featured but non-working example.

Give the project a name, find KDE 4 and setup CMAKE_MODULE_PATH. This has the effect that cmake will also use check the ${CMAKE_SOURCE_DIR}/cmake directory for files if you use include(somefile) or find_package(something). Please note that this directory is added to the former contents of CMAKE_MODULE_PATH. This is important, since if find_package(KDE4) was successfully, it will have setup CMAKE_MODULE_PATH so that it points to the directory where the cmake files installed with kdelibs are located.

project(allForK)
find_package(KDE4 REQUIRED)
set(CMAKE_MODULE_PATH ${CMAKE_SOURCE_DIR}/cmake ${CMAKE_MODULE_PATH})
