#.rst:
# ECMInstallIcons
# ---------------
#
# Installs icons, sorting them into the correct directories according to the
# FreeDesktop.org icon naming specification.
#
# ::
#
# ecm_install_icons(ICONS <icon> [<icon> [...]]
# DESTINATION <icon_install_dir>
# [LANG <l10n_code>]
# [THEME <theme>])
#
# The given icons, whose names must match the pattern::
#
# <size>-<group>-<name>.<ext>
#
# will be installed to the appropriate subdirectory of DESTINATION according to
# the FreeDesktop.org icon naming scheme. By default, they are installed to the
# "hicolor" theme, but this can be changed using the THEME argument. If the
# icons are localized, the LANG argument can be used to install them in a
# locale-specific directory.
#
# ``<size>`` is a numeric pixel size (typically 16, 22, 32, 48, 64, 128 or 256)
# or ``sc`` for scalable (SVG) files, ``<group>`` is one of the standard
# FreeDesktop.org icon groups (actions, animations, apps, categories, devices,
# emblems, emotes, intl, mimetypes, places, status) and ``<ext>`` is one of
# ``.png``, ``.mng`` or ``.svgz``.
#
# The typical installation directory is ``share/icons``.
#
# .. code-block:: cmake
#
# ecm_install_icons(ICONS 22-actions-menu_new.png
# DESTINATION share/icons)
#
# The above code will install the file ``22-actions-menu_new.png`` as
# ``${CMAKE_INSTALL_PREFIX}/share/icons/<theme>/22x22/actions/menu_new.png``
#
# Users of the :kde-module:`KDEInstallDirs` module would normally use
# ``${ICON_INSTALL_DIR}`` as the DESTINATION, while users of the GNUInstallDirs
# module should use ``${CMAKE_INSTALL_DATAROOTDIR}/icons``.
#
# An old form of arguments will also be accepted::
#
# ecm_install_icons(<icon_install_dir> [<l10n_code>])
#
# This matches files named like::
#
# <theme><size>-<group>-<name>.<ext>
#
# where ``<theme>`` is one of
# * ``hi`` for hicolor
# * ``lo`` for locolor
# * ``cr`` for the Crystal icon theme
# * ``ox`` for the Oxygen icon theme
# * ``br`` for the Breeze icon theme
#
# With this syntax, the file ``hi22-actions-menu_new.png`` would be installed
# into ``<icon_install_dir>/hicolor/22x22/actions/menu_new.png``
