#.rst:
# ECMInstallIcons
# ---------------
#
# Installs icons, sorting them into the correct directories according to the
# FreeDesktop.org icon naming specification.
#
# ::
#
# ecm_install_icons(<icon_install_dir> [<l10n_code>])
#
# Installs all icons found in ``CMAKE_CURRENT_SOURCE_DIR`` to the correct
# subdirectory of ``<icon_install_dir>``. ``<icon_install_dir>`` should
# typically be something like ``share/icons``, although users of the
# :kde-module:`KDEInstallDirs` module would normally do
#
# .. code-block:: cmake
#
# ecm_install_icons(${ICON_INSTALL_DIR})
#
# The icons must be named in the form::
#
# <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
#
# ``<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``.
#
# For example the file ``hi22-action-menu_new.png`` would be installed into
# ``<icon_install_dir>/hicolor/22x22/actions/menu_new.png``
