See the platform notes below for any # recommendations about icon sizes. # # ``SIDEBAR_ICONS`` can be used to add Mac OS X sidebar # icons to the generated iconset. They are used when a folder monitored by the # application is dragged into Finder's sidebar. Since 5.49. # # ``OUTFILE_BASENAME`` will be used as the basename for the icon file. If # you specify it, the icon file will be called ``.icns`` on Mac OS X # and ``.ico`` on Windows. If you don't specify it, it defaults # to ``.``. Since 5.49. # # # Windows notes # * Icons are compiled into the executable using a resource file. # * Icons may not show up in Windows Explorer if the executable # target does not have the ``WIN32_EXECUTABLE`` property set. # * One of the tools png2ico (See :find-module:`FindPng2Ico`) or # icotool (see :find-module:`FindIcoTool`) is required. # * Supported sizes: 16, 24, 32, 48, 64, 128, 256, 512 and 1024. # # Mac OS X notes # * The executable target must have the ``MACOSX_BUNDLE`` property set. # * Icons are added to the bundle. # * If the ksvg2icns tool from KIconThemes is available, .svg and .svgz # files are accepted; the first that is converted successfully to .icns # will provide the application icon. SVG files are ignored otherwise. # * The tool iconutil (provided by Apple) is required for bitmap icons. # * Supported sizes: 16, 32, 64, 128, 256 (and 512, 1024 after OS X 10.9). # * At least a 128x128px (or an SVG) icon is required. # * Larger sizes are automatically used to substitute for smaller sizes on # "Retina" (high-resolution) displays. For example, a 32px icon, if # provided, will be used as a 32px icon on standard-resolution displays, # and as a 16px-equivalent icon (with an "@2x" tag) on high-resolution # displays. That is why you should provide 64px and 1024px icons although # they are not supported anymore directly. Instead they will be used as # 32px@2x and 512px@2x. ksvg2icns handles this internally. # * This function sets the ``MACOSX_BUNDLE_ICON_FILE`` variable to the name # of the generated icns file, so that it will be used as the # ``MACOSX_BUNDLE_ICON_FILE`` target property when you call # ``add_executable``. # * Sidebar icons should typically provided in 16, 32, 64, 128 and 256px. # # Since 1.7.0. #============================================================================= # Copyright 2014 Alex Merry # Copyright 2014 Ralf Habacker # Copyright 2006-2009 Alexander Neundorf, # Copyright 2006, 2007, Laurent Montel, # Copyright 2007 Matthias Kretz # # Redistribution and use in source and binary forms, with or without # modification, are permitted provided that the following conditions # are met: # # 1.
