CMake:How To Build KDE4 Software

Let's just start with a simple example for an application, let's name it, well, kFoo:

# give the project a name, so that the project files
# for KDevelop/XCode/MSVC will have a good name
project(kfoo)

# find the KDE 4 installation
find_package(KDE4 REQUIRED)

# setup the required include dirs
include_directories( ${KDE4_INCLUDES} )

# the source files of your project
set(mySources main.cpp mywidget.cpp mypart.cpp)

# automoc handling
kde4_automoc( ${mySources} )

# create an executable named kfoo from the sources
kde4_add_executable(kfoo ${mySources})

# link kfoo to the kdeui and the kparts libraries
target_link_libraries(kfoo ${KDE4_KDEUI_LIBS} ${KDE4_KPARTS_LIBS} )

# install kfoo, its desktop file and its icons
install_targets( /bin kfoo)
install_files( ${XDG_APPS_DIR} FILES kfoo.desktop)
kde4_install_icons( ${ICON_INSTALL_DIR} hicolor)
