# - Function for installing icons
# This module provides the function ECM_INSTALL_ICONS().
# ECM_INSTALL_ICONS installs all icons in the current path that
# match a specific file naming convention into into the directory provided
# following the Freedesktop.org icon naming spec
# http://standards.freedesktop.org/icon-naming-spec/icon-naming-spec-latest.html
# The filenames of the icons in the directory must be in the following format
# in order to be installed
# themeSize-Group-name.extension
# The following file extensions are supported
# .png
# .mng
# .svgz
# Where the theme is one of:
# "hi" for hicolor
# "lo" for locolor
# "cr" for the crystal icon theme
# "ox" for the oxygen icon theme
# Size refers to the size of one dimension of the icon
# Typically, 16, 22, 32, 48, 64, 128 or 256
# For svgz files the size should be set to "sc"
# For example the file
# hi22-action-menu_new.png
# would be installed into
# PREFIX/hicolor/22x22/actions/menu_new.png
# a "map" of short type names to the directories
# unknown names should give empty results
# xdg icon naming specification compatibility
