# KDEInstallDirs5

Define KDE standard installation directories for Qt5/KF5 based software.

Note that none of the variables defined by this module provide any information about the location of already-installed KDE software.

Also sets `CMAKE_INSTALL_PREFIX` to the installation prefix of ECM, unless that variable has been already explicitly set by something else (since 5.61 and with CMake >= 3.7).

Inclusion of this module defines the following variables:

`KDE_INSTALL_<dir>`

  destination for files of a given type

`KDE_INSTALL_FULL_<dir>`

  corresponding absolute path

If `KDE_INSTALL_USE_QT_SYS_PATHS` is set to `TRUE` before including this module, the default values for some variables are instead queried from Qt5’s qmake (where mentioned in the parentheses above). If not set, it will default to `TRUE` if Qt5’s qmake is found and it’s `QT_INSTALL_PREFIX` is the same as `CMAKE_INSTALL_PREFIX`, otherwise default to `FALSE`. This variable should NOT be set from within CMakeLists.txt files, instead is intended to be set manually when configuring a project which uses KDEInstallDirs (e.g. by packagers).

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 if the `KDE_INSTALL_<dir>`, `CMAKE_INSTALL_<dir>` or deprecated form of the variable are set before `include(KDEInstallDirs)`, they won’t be overwritten by `KDEInstallDirs`. This is useful if you eg. want to use CMake command line variable definitions to set custom values. There are however some other implications you need to be aware of: `GNUInstallDirs` defines `CMAKE_INSTALL_<dir>` variables, before hence `KDEInstallDirs` will not overwrite them if it is included later. In most cases this is unintended and if you need to include `GNUInstallDirs` you should always do that after after you included `KDEInstallDirs`.

If you set custom values to `KDE_INSTALL_<dir>` or `CMAKE_INSTALL_<dir>` as described above always both forms of the variable will be affected. The effect of passing multiple forms of the same variable eg. on the command line (such as `KDE_INSTALL_BINDIR` and `CMAKE_INSTALL_BINDIR`) is undefined and should be avoided.

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 5.82.0, prior to that available as `KDEInstallDirs`.

NB: The variables starting `KDE_INSTALL_` are available since 1.6.0, unless otherwise noted with the variable.

The `KDE_INSTALL_PREFIX_SCRIPT` option will install a ${CMAKE_INSTALL_PREFIX}/prefix.sh file that allows to easily incorporate the necessary environment variables for the prefix into a process.
