/* 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.
*/
