# 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`.

    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 `KDEInstallDirs` module would normally use `${KDE_INSTALL_ICONDIR}` as the DESTINATION, while users of the GNUInstallDirs module should use `${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`

Since pre-1.0.0.
