28 dnl adds support for --with-gdlib-prefix and --with-gdlib-config
29 dnl command line options
31 dnl Test for gdlib, and define GDLIB_CFLAGS, GDLIB_LIBS and GDLIB_CONFIG_NAME
32 dnl environment variable to override the default name of the gdlib-config script
33 dnl to use. Set GDLIB_CONFIG_PATH to specify the full path to gdlib-config -
34 dnl in this case the macro won't even waste time on tests for its existence.
