# This module defines also a bunch of variables used as locations for install directories
# for files of the package which is using this module. These variables don't say
# anything about the location of the installed KDE.
# They can be relative (to CMAKE_INSTALL_PREFIX) or absolute.
#
# BIN_INSTALL_DIR - the directory where executables will be installed (default is prefix/bin)
# SBIN_INSTALL_DIR - the directory where system executables will be installed (default is prefix/sbin)
# LIB_INSTALL_DIR - the directory where libraries will be installed (default is prefix/lib)
# CONFIG_INSTALL_DIR - the directory where config files will be installed
# DATA_INSTALL_DIR - the parent directory where applications can install their data
# ICON_INSTALL_DIR - the directory where the icons will be installed (default prefix/share/icons/)
# INFO_INSTALL_DIR - the directory where info files will be installed (default prefix/info)
# KCFG_INSTALL_DIR - the directory where kconfig files will be installed

# PLUGIN_INSTALL_DIR - the subdirectory relative to the install prefix where plugins will be installed (default is ${KDE4_LIB_INSTALL_DIR})
# IMPORTS_INSTALL_DIR - the subdirectory relative to the install prefix where imports will be installed
# SERVICES_INSTALL_DIR - the directory where service (desktop, protocol, ...) files will be installed
# SERVICETYPES_INSTALL_DIR - the directory where servicestypes desktop files will be installed
# SOUND_INSTALL_DIR - the directory where sound files will be installed

# XDG_DIRECTORY_INSTALL_DIR- the XDG directory
# XDG_MIME_INSTALL_DIR - the XDG mimetypes install dir
# DBUS_INTERFACES_INSTALL_DIR - the directory where dbus interfaces will be installed (default is prefix/share/dbus-1/interfaces)
# DBUS_SERVICES_INSTALL_DIR - the directory where dbus services will be installed (default is prefix/share/dbus-1/services )
# DBUS_SYSTEM_SERVICES_INSTALL_DIR - the directory where dbus system services will be installed (default is prefix/share/dbus-1/system-services )
#
# The variable INSTALL_TARGETS_DEFAULT_ARGS can be used when installing libraries
# or executables into the default locations.
# The INSTALL_TARGETS_DEFAULT_ARGS variable should be used when libraries are installed.
# It should also be used when installing applications.
# The variable MUST NOT be used for installing plugins.
# It also MUST NOT be used for executables which are intended to go into sbin/ or libexec/.
#
# Usage is like this:
# install(TARGETS kdecore kdeui ${INSTALL_TARGETS_DEFAULT_ARGS} )
#
# This will install libraries correctly under UNIX, OSX and Windows (i.e. dll's go
# into bin/.
#
#
# The following user adjustable options are provided:
#
# KDE4_ADD_KCFG_FILES (SRCS_VAR [GENERATE_MOC] [USE_RELATIVE_PATH] file1.kcfgc ... fileN.kcfgc)
# Use this to add KDE config compiler files to your application/library.
# Use optional GENERATE_MOC to generate moc if you use signals in your kcfg files.
# Use optional USE_RELATIVE_PATH to generate the classes in the build following the given
# relative path to the file.
#
# KDE4_ADD_WIDGET (SRCS_VAR file1.widgets ... fileN.widgets)
# Use this to add widget description files for the makekdewidgets code generator
# for Qt Designer plugins.
#
# KDE4_ADD_PLUGIN ( name [WITH_PREFIX] file1 ... fileN )
# Create a KDE plugin (KPart, kioslave, etc.) from the given source files.
# If WITH_PREFIX is given, the resulting plugin will have the prefix "lib", otherwise it won't.
#
# KDE4_ADD_TEST (testname file1 ... fileN)
# add a unit test, which is executed when running make test. The targets
# are build and executed only if the ENABLE_TESTING option is enabled.
# KDESRCDIR is set to the source directory of the test, this can be used
# with KGlobal::dirs()->addResourceDir( "data", KDESRCDIR )
#
# KDE4_ADD_MANUAL_TEST (testname file1 ... fileN)
# same as KDE_ADD_TEST() except that the test is not run on `make test`
#
# KDE4_INSTALL_ICONS ( path theme)
# Installs all png and svgz files in the current directory to the icon
# directory given in path, in the subdirectory for the given icon theme.
#
# KDE4_CREATE_MANPAGE ( docbookfile section )
# Create the manpage for the specified section from the docbookfile
# The resulting manpage will be installed to <installdest> when using
# INSTALL_DESTINATION <installdest>, or to <installdest>/<subdir> if
# SUBDIR <subdir> is specified.
#
# KDE4_INSTALL_AUTH_HELPER_FILES ( HELPER_TARGET HELPER_ID HELPER_USER )
# This macro adds the needed files for an helper executable meant to be used by applications using KAuth.
# It accepts the helper target, the helper ID (the DBUS name) and the user under which the helper will run on.
# This macro takes care of generate the needed files, and install them in the right location. This boils down
# to a DBus policy to let the helper register on the system bus, and a service file for letting the helper
# being automatically activated by the system bus.
# *WARNING* You have to install the helper in ${LIBEXEC_INSTALL_DIR} to make sure everything will work.
#
#
#
# A note on the possible values for CMAKE_BUILD_TYPE and how KDE handles
# the flags for those buildtypes. FindKDE4Internal supports the values
# Release, RelWithDebInfo and Debug:
#
# Release
# optimised for speed, qDebug/kDebug turned off, no debug symbols, no asserts
# RelWithDebInfo (Release with debug info)
# similar to Release, optimised for speed, but with debugging symbols on (-g)
# Debug
# optimised but debuggable, debugging on (-g)
# (-fno-reorder-blocks -fno-schedule-insns -fno-inline)
# MinSizeRel:
# optimization for smallest size, no debugging information
#
#
# The default buildtype is RelWithDebInfo.
# It is expected that the "Debug" build type be still debuggable with gdb
# without going all over the place, but still produce better performance.
# It's also important to note that gcc cannot detect all warning conditions
# unless the optimiser is active.
#
#
# This module allows to depend on a particular minimum version of kdelibs.
# To acomplish that one should use the appropriate cmake syntax for
# find_package. For example to depend on kdelibs >= 4.1.0 one should use
#
# find_package(KDE4 4.18.0 REQUIRED)
#
# In earlier versions of KDE you could use the variable KDE_MIN_VERSION to
# have such a dependency. This variable is deprecated with KDE 4.2.0, but
# will still work to make the module backwards-compatible.
