NAME

6       ecm - Extra CMake Modules
7

INTRODUCTION

9       The  Extra  CMake Modules package, or ECM, adds to the modules provided
10       by CMake, including ones used by find_package() to  find  common  soft‐
11       ware, ones that can be used directly in CMakeLists.txt files to perform
12       common tasks and toolchain files that must be specified on the command‐
13       line by the user.
14
15       In  addition,  it  provides common build settings used in software pro‐
16       duced by the KDE community.
17
18       While the driving force of this module  is  to  reduce  duplication  in
19       CMake  scripts across KDE software, it is intended to be useful for any
20       software that uses the CMake build system.
21

USAGE

23       To use ECM, add the following to your CMakeLists.txt:
24
25          find_package(ECM REQUIRED NO_MODULE)
26          set(CMAKE_MODULE_PATH ${ECM_MODULE_PATH})
27
28       (note that you may want  to  append  ${ECM_MODULE_PATH}  to  CMAKE_MOD‐
29       ULE_PATH rather than discarding the existing value).  You can then just
30       include the modules you require, or use find_package() as needed.   For
31       example:
32
33          include(ECMInstallIcons)
34
35       Developers of KDE software will often want to use the KDE standard set‐
36       tings provided by ECM; they can do the following:
37
38          find_package(ECM REQUIRED NO_MODULE)
39          set(CMAKE_MODULE_PATH ${ECM_MODULE_PATH})
40          include(KDEInstallDirs)
41          include(KDECompilerSettings)
42          include(KDECMakeSettings)
43
44       Note that any combination of the above includes can be used if you only
45       want  some  of the settings.  Some of the functionality of KDECMakeSet‐
46       tings can also be selectively disabled.
47
48   Organization
49       ECM provides four different types of modules.
50
51       · Core modules provide helpful macros for use in project CMake scripts.
52         See ecm-modules(7) for more information.
53
54       · Find  modules extend the functionality of CMake’s find_package() com‐
55         mand.  See ecm-find-modules(7) for more information.
56
57       · KDE modules provide common settings for  software  produced  by  KDE;
58         much  of this may also be useful to other projects.  See ecm-kde-mod‐
59         ules(7) for more information.
60
61       · Toolchain files change the build tools and targets used by CMake. See
62         ecm-toolchains(7) for more information.
63
64       The ${ECM_MODULE_DIR}, ${ECM_FIND_MODULE_DIR} and ${ECM_KDE_MODULE_DIR}
65       variables may be used instead of ${ECM_MODULE_PATH} if  you  only  need
66       some of this functionality.
