/* USER-SELECTABLE CONFIGURATION MACROS */
/* */
/* This file contains the default configuration macro definitions for */
/* a standard build of the FreeType library. There are three ways to */
/* use this file to build project-specific versions of the library: */
/* */
/* - You can modify this file by hand, but this is not recommended in */
/* cases where you would like to build several versions of the */
/* library from a single source directory. */
/* */
/* - You can put a copy of this file in your build directory, more */
/* precisely in `$BUILD/freetype/config/ftoption.h', where `$BUILD' */
/* is the name of a directory that is included _before_ the FreeType */
/* include path during compilation. */
/* */
/* The default FreeType Makefiles and Jamfiles use the build */
/* directory `builds/<system>' by default, but you can easily change */
/* that for your own projects. */
/* */
/* - Copy the file <ft2build.h> to `$BUILD/ft2build.h' and modify it */
/* slightly to pre-define the macro FT_CONFIG_OPTIONS_H used to */
/* locate this file during the build. For example, */
/* */
/* #define FT_CONFIG_OPTIONS_H <myftoptions.h> */
/* #include <freetype/config/ftheader.h> */
/* */
/* will use `$BUILD/myftoptions.h' instead of this file for macro */
/* definitions. */
/* */
/* Note also that you can similarly pre-define the macro */
/* FT_CONFIG_MODULES_H used to locate the file listing of the modules */
/* that are statically linked to the library at compile time. By */
/* default, this file is <freetype/config/ftmodule.h>. */
/* */
/* We highly recommend using the third method whenever possible. */
