Usage: perl Makefile.PL [options]
Configure GD module.
Options:
-options "JPEG,FT,PNG,GIF,XPM,ANIMGIF" feature options, separated by commas
-lib_gd_path path path to libgd
-lib_ft_path path path to Freetype library
-lib_png_path path path to libpng
-lib_jpeg_path path path to libjpeg
-lib_xpm_path path path to libxpm
-lib_zlib_path path path to libpng
If no options are passed on the command line. The program will
attempt to autoconfigure itself with the gdlib-config program (present
in GD versions 2.0.27 or later). Otherwise it will prompt for these
values interactively.
