NAME
ecm-kde-modules - ECM KDE Modules Reference
INTRODUCTION
Extra CMake Modules (ECM) provides several modules that provide default settings (like
installation directories, compiler flags and other CMake options) aimed at software
produced by the KDE modules; these are documented here. ECM also provides modules with
more general functionality, documented in ecm-modules(7), and ones that extend the
functionality of the find_package command, documented in ecm-find-modules(7).
To use these modules, you need to tell CMake to find the ECM package, and then add either
${ECM_MODULE_PATH} or ${ECM_KDE_MODULE_DIR} to the CMAKE_MODULE_PATH variable:
find_package(ECM REQUIRED NO_MODULE)
set(CMAKE_MODULE_PATH ${ECM_MODULE_DIR})
Using ${ECM_MODULE_PATH} will also make the other types of modules available.
ALL KDE MODULES
KDECMakeSettings
Changes various CMake settings to what the KDE community views as more sensible defaults.
It is recommended to include this module with the NO_POLICY_SCOPE flag, otherwise you may
get spurious warnings with some versions of CMake.
It is split into three parts, which can be independently disabled if desired.
Runtime Paths
The default runtime path (used on Unix systems to search for dynamically-linked libraries)
is set to include the location that libraries will be installed to (as set in
LIB_INSTALL_DIR), and also the linker search path.
Note that LIB_INSTALL_DIR needs to be set before including this module. Typically, this
is done by including the KDEInstallDirs module.
This section can be disabled by setting KDE_SKIP_RPATH_SETTINGS to TRUE before including
this module.
Testing
Testing is enabled by default, and an option (BUILD_TESTING) is provided for users to
control this. See the CTest module documentation in the CMake manual for more details.
This section can be disabled by setting KDE_SKIP_TEST_SETTINGS to TRUE before including
this module.
Build Settings
Various CMake build defaults are altered, such as searching source and build directories
for includes first and enabling automoc by default.
This section can be disabled by setting KDE_SKIP_BUILD_SETTINGS to TRUE before including
this module.
This section also provides an "uninstall" target that can be individually disabled by
setting KDE_SKIP_UNINSTALL_TARGET to TRUE before including this module.
By default on OS X, X11 and XCB related detections are disabled. However if the need would
arise to use these technologies, the detection can be enabled by setting APPLE_FORCE_X11
to ON.
A warning is printed for the developer to know that the detection is disabled on OS X.
This message can be turned off by setting APPLE_SUPPRESS_X11_WARNING to ON.
Since pre-1.0.0.
ENABLE_CLAZY option is added (OFF by default) when clang is being used. Turning this
option on will force clang to load the clazy plugins for richer warnings on Qt-related
code.
If clang is not being used, this won't have an effect. See
https://quickgit.kde.org/?p=clazy.git&a=blob&f=README&o=plain
Since 5.17.0
• Uninstall target functionality since 1.7.0.
• APPLE_FORCE_X11 option since 5.14.0 (detecting X11 was previously the default behavior)
• APPLE_SUPPRESS_X11_WARNING option since 5.14.0
KDECompilerSettings
Set useful compile and link flags for C++ (and C) code.
Enables many more warnings than the default, and sets stricter modes for some compiler
features. By default, exceptions are disabled; kde_target_enable_exceptions() can be used
to re-enable them for a specific target.
NB: it is recommended to include this module with the NO_POLICY_SCOPE flag, otherwise you
may get spurious warnings with some versions of CMake.
This module provides the following functions:
kde_source_files_enable_exceptions([file1 [file2 [...]]])
Enables exceptions for specific source files. This should not be used on source files in
a language other than C++.
kde_target_enable_exceptions(target <INTERFACE|PUBLIC|PRIVATE>)
Enables exceptions for a specific target. This should not be used on a target that has
source files in a language other than C++.
kde_enable_exceptions()
Enables exceptions for C++ source files compiled for the CMakeLists.txt file in the
current directory and all subdirectories.
Since pre-1.0.0.
KDEFrameworkCompilerSettings
Set stricter compile and link flags for KDE Frameworks modules.
The KDECompilerSettings module is included and, in addition, various defines that affect
the Qt libraries are set to enforce certain conventions.
For example, constructions like QString("foo") are prohibited, instead forcing the use of
QLatin1String or QStringLiteral, and some Qt-defined keywords like signals and slots will
not be defined.
NB: it is recommended to include this module with the NO_POLICY_SCOPE flag, otherwise you
may get spurious warnings with some versions of CMake.
Since pre-1.0.0.
KDEInstallDirs
Define KDE standard installation directories.
Note that none of the variables defined by this module provide any information about the
location of already-installed KDE software.
Inclusion of this module defines the following variables:
KDE_INSTALL_<dir>

If KDE_INSTALL_DIRS_NO_DEPRECATED is set to TRUE before including this module, the
deprecated variables (listed in the square brackets above) are not defined.
In addition, for each KDE_INSTALL_* variable, an equivalent CMAKE_INSTALL_* variable is
defined. If KDE_INSTALL_DIRS_NO_DEPRECATED is set to TRUE, only those variables defined by
the GNUInstallDirs module (shipped with CMake) are defined. If
KDE_INSTALL_DIRS_NO_CMAKE_VARIABLES is set to TRUE, no variables with a CMAKE_ prefix will
be defined by this module (other than CMAKE_INSTALL_DEFAULT_COMPONENT_NAME - see below).
The KDE_INSTALL_<dir> variables (or their CMAKE_INSTALL_<dir> or deprecated counterparts)
may be passed to the DESTINATION options of install() commands for the corresponding file
type. They are set in the CMake cache, and so the defaults above can be overridden by
users.
Note that the KDE_INSTALL_<dir>, CMAKE_INSTALL_<dir> or deprecated form of the variable
can be changed using CMake command line variable definitions; in either case, all forms of
the variable will be affected. The effect of passing multiple forms of the same variable
on the command line (such as KDE_INSTALL_BINDIR and CMAKE_INSTALL_BINDIR is undefined.
The variable KDE_INSTALL_TARGETS_DEFAULT_ARGS is also defined (along with the deprecated
form INSTALL_TARGETS_DEFAULT_ARGS). This should be used when libraries or user-executable
applications are installed, in the following manner:
install(TARGETS mylib myapp ${KDE_INSTALL_TARGETS_DEFAULT_ARGS})
It MUST NOT be used for installing plugins, system admin executables or executables only
intended for use internally by other code. Those should use KDE_INSTALL_PLUGINDIR,
KDE_INSTALL_SBINDIR or KDE_INSTALL_LIBEXECDIR respectively.
Additionally, CMAKE_INSTALL_DEFAULT_COMPONENT_NAME will be set to ${PROJECT_NAME} to
provide a sensible default for this CMake option.
Note that mixing absolute and relative paths, particularly for BINDIR, LIBDIR and
INCLUDEDIR, can cause issues with exported targets. Given that the default values for
these are relative paths, relative paths should be used on the command line when possible
(eg: use -DKDE_INSTALL_LIBDIR=lib64 instead of -DKDE_INSTALL_LIBDIR=/usr/lib/lib64 to
override the library directory).
Since pre-1.0.0.
NB: The variables starting KDE_INSTALL_ are only available since 1.6.0. The APPDIR
install variable is available since 1.1.0.
KDETemplateGenerator
Packages KApptemplate/KDevelop compatible application templates
This module provides a functionality to package in a tarball and install project templates
compatible with the format used by KApptemplate and KDevelop. Useful for providing minimal
examples for the usage of the KDE Frameworks.
This module provides the following function:
kde_package_app_templates( TEMPLATES template1 [template2] [...] INSTALL_DIR directory)
INSTALL_DIR is the directory to install the template package to. In most cases you will
want to use the variable KDE_INSTALL_KTEMPLATESDIR from KDEInstallDirs.
TEMPLATES lists subdirectories containing template files; each <template> directory will
be packaged into a file named <template>.tar.bz2 and installed to the appropriate
location.
The template is a minimal source tree of an application as if it was an application
project by itself, with names (file names or text inside) the text files replaced by the
following placeholders when needed:
%{PROJECTDIRNAME}
%{APPNAMELC}-%{VERSION} for KAppTemplate
%{APPNAME}
project name as entered by user ex: MyKApp
%{APPNAMELC}
project name in lower case ex: mykapp
%{APPNAMEUC}
project name in upper case ex: MYKAPP
%{CPP_TEMPLATE}
license header for cpp file
%{H_TEMPLATE}
license header for h file
%{AUTHOR}
author name ex: George Ignacious
%{EMAIL}
author email ex: foo@bar.org
%{VERSION}
project version ex: 0.1
%{dest}
used in .kdevtemplate
%{src} used in .kdevtemplate
Multiple templates can be passed at once.
Since 5.18
