# 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>`
  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 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 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.
