A page to document the variables, macros and other useful stuff we have to use CMake as the KDE4 buildsystem.

You may also want to visit the automatically generated documentation for FindKDE4Internal.cmake, which is generated directly from the current FindKDE4Internal.cmake and may be more up-to-date.

[edit] Buildtypes

CMake supports different build types for compiling the source code. The following built-in build types are available to the CMake buildsystem:

Release
optimized for speed, no debug symbols or qDebug/kDebug messages, no asserts
RelWithDebInfo
similiar to release, but with debug symbols for backtraces (-g). This is the default if none other is chosen.
Debug
optimized for speed, but debuggable (you can still single-step through functions and set most breakpoints) and with debug symbols for backtraces (-g)
DebugFull
no optimizations, full debug support and information (-g3). Note that some compiler warnings rely on the optimizer being available.
Profile
adds coverage flags (-ftest-coverage -fprofile-arcs) to DebugFull.
None
the build flags are manually set using the CMAKE_CXX_FLAGS option.

You can tell CMake the desired build type by passing the relevant type as command line option, for instance:

cmake /path/to/source -DCMAKE_BUILD_TYPE=Debug

[edit] Macros

Lots of useful macros: (Question: Is there a URL to download these macros?)

  • KDE4_ADD_UI_FILES (SRCS_VAR file1.ui ... fileN.ui)

Use this to add Qt designer ui files to your application/library.

  • KDE4_ADD_UI3_FILES (SRCS_VAR file1.ui ... fileN.ui)

Use this to add Qt designer ui files from Qt version 3 to your application/library.

  • KDE4_ADD_KCFG_FILES (SRCS_VAR [GENERATE_MOC] file1.kcfgc ... fileN.kcfgc)

Use this to add KDE config compiler files to your application/library.

Use optional GENERATE_MOC to generate moc if you use signals in your kcfg files.

  • KDE4_ADD_WIDGET_FILES (SRCS_VAR file1.widgets ... fileN.widgets)

Use this to add widget description files for the makekdewidgets code generator for Qt Designer plugins.

  • KDE4_ADD_PLUGIN ( name [WITH_PREFIX] file1 ... fileN )

Create a KDE plugin (KPart, kioslave, etc.) from the given source files.

It supports KDE4_ENABLE_FINAL.

If WITH_PREFIX is given, the resulting plugin will have the prefix "lib", otherwise it won't.

It creates and installs an appropriate libtool la-file.

  • KDE4_ADD_KDEINIT_EXECUTABLE (name [NOGUI] [RUN_UNINSTALLED] file1 ... fileN)

Create a KDE application in the form of a module loadable via kdeinit.

A library named kdeinit_<name> will be created and a small executable which links to it.

It supports KDE4_ENABLE_FINAL

If the executable has to be run from the buildtree (e.g. unit tests and code generators used later on when compiling), set the option RUN_UNINSTALLED.

If the executable doesn't have a GUI, use the option NOGUI. By default on OS X application bundles are created, with the NOGUI option no bundles but simple executables are created. Currently it doesn't have any effect on other platforms.

  • KDE4_ADD_EXECUTABLE (name [NOGUI] [RUN_UNINSTALLED] file1 ... fileN)

Equivalent to ADD_EXECUTABLE(), but additionally adds some more features:

** support for KDE4_ENABLE_FINAL
** support for automoc
** automatic RPATH handling

If the executable has to be run from the buildtree (e.g. unit tests and code generators used later on when compiling), set the option RUN_UNINSTALLED.

If the executable doesn't have a GUI, use the option NOGUI. By default on OS X application bundles are created, with the NOGUI option no bundles but simple executables are created. Currently it doesn't have any effect on other platforms.

  • KDE4_ADD_LIBRARY (name [STATIC | SHARED | MODULE ] file1 ... fileN)

Equivalent to ADD_LIBRARY(), but additionally it supports KDE4_ENABLE_FINAL and under Windows it adds a -DMAKE_<name>_LIB definition to the compilation.

  • KDE4_ADD_UNIT_TEST (testname [TESTNAME targetname] file1 ... fileN)

Add a unit test, which is executed when running make test

It will be built with RPATH pointing to the build dir

The targets are always created, but only built for the "all" target if the option KDE4_BUILD_TESTS is enabled. Otherwise the rules for the target are created but not built by default. You can build them by manually building the target.

The name of the target can be specified using TESTNAME <targetname>, if it is not given the macro will default to the <testname>

  • KDE4_ADD_TEST_EXECUTABLE (name file1 ... fileN)

Add a test executable

It will be built with RPATH pointing to the build dir

The targets are always created, but only built for the "all" target if the option KDE4_BUILD_TESTS is enabled. Otherwise the rules for the target are created but not built by default. You can build them by manually building the target.

KDESRCDIR is set to the source directory of the test, this can be used with KGlobal::dirs()->addResourceDir( "data", KDESRCDIR ); to be able to use xmlgui and other things in the test, that normally require installation

  • KDE4_UPDATE_ICONCACHE()

Notifies the icon cache that new icons have been installed by updating mtime of ${ICON_INSTALL_DIR}/hicolor directory.

Installs all png and svgz files in the current directory that comply to the icon naming scheme to the icon directory given in path, in the subdirectory for the given icon theme.

  • KDE4_ADD_APP_ICON(appsources pattern)

Mac OS X and Windows only: Adds application icon to target source list. This macro adds an application icon to the specified target. Mac OS X notes: the application icon is added to a Mac OS X bundle so that Finder and friends show the right thing. You need to provide a 128x128 version of the icon for this to work. Windows notes: the application icon(s) are compiled into the application binary.

Parameters:

  1. 'appsources' - specifies the list of source files
  2. 'pattern' - regular expression for searching application icons

Examples: KDE4_ADD_APP_ICON(myapp_sources "pics/cr*-myapp.png") or KDE4_ADD_APP_ICON(myapp_sources "${KDE4_INSTALL_DIR}/share/icons/oxygen/*/apps/myapp.png")

  • KDE4_CREATE_HANDBOOK( docbookfile )

Create the handbook from the docbookfile (using meinproc)

  • KDE4_SET_CUSTOM_TARGET_PROPERTY - deprecated, do not use
  • KDE4_GET_CUSTOM_TARGET_PROPERTY - deprecated, do not use
  • KDE4_MOC_HEADERS
  • KDE4_HANDLE_AUTOMOC
  • KDE4_CREATE_FINAL_FILES
  • KDE4_REMOVE_OBSOLETE_CMAKE_FILES
  • KDE4_NO_ENABLE_FINAL
