ecm - Extra CMake Modules
The Extra CMake Modules package, or ECM, adds to the modules provided by CMake, including ones used by find_package() to find common software, ones that can be used directly in CMakeLists.txt files to perform common tasks and toolchain files that must be specified on the commandline by the user.
In addition, it provides common build settings used in software produced by the KDE community.
While the driving force of this module is to reduce duplication in CMake scripts across KDE software, it is intended to be useful for any software that uses the CMake build system.
To use ECM, add the following to your CMakeLists.txt:
find_package(ECM REQUIRED NO_MODULE) set(CMAKE_MODULE_PATH ${ECM_MODULE_PATH})
(note that you may want to append ${ECM_MODULE_PATH} to CMAKE_MODULE_PATH rather than discarding the existing value). You can then just include the modules you require, or use find_package() as needed. For example:
include(ECMInstallIcons)
Developers of KDE software will often want to use the KDE standard settings provided by ECM; they can do the following:
find_package(ECM REQUIRED NO_MODULE) set(CMAKE_MODULE_PATH ${ECM_MODULE_PATH}) include(KDEInstallDirs) include(KDECompilerSettings) include(KDECMakeSettings)
Note that any combination of the above includes can be used if you only want some of the settings. Some of the functionality of KDECMakeSettings can also be selectively disabled.
ECM provides four different types of modules.
The ${ECM_MODULE_DIR}, ${ECM_FIND_MODULE_DIR} and ${ECM_KDE_MODULE_DIR} variables may be used instead of ${ECM_MODULE_PATH} if you only need some of this functionality.
The ecm-developer(7) manual contains more information about developing for Extra CMake Modules.
