Build a dynamically loadable module for *magick
By default, a dynamically loadable module is built for *magick (i.e. `--with-magick=module`) when: * ImageMagick or GraphicsMagick is found; * GModule is supported (`gmodule_supported` pkg-config variable). This can be overridden on the command line with: * `--without-magick` - to disable *magick usage; * `--with-magick[=yes]` - to restore the previous behavior; * `--disable-modules` - to disable the build of dynamic modules.
