- /* 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 `$BUILD/config/ftoption.h', where `$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 <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 <config/ftmodule.h>. */

- /* */

- /* We highly recommend using the third method whenever possible. */
