30 /* USER-SELECTABLE CONFIGURATION MACROS */
31 /* */
32 /* This file contains the default configuration macro definitions for */
33 /* a standard build of the FreeType library. There are three ways to */
34 /* use this file to build project-specific versions of the library: */
35 /* */
36 /* - You can modify this file by hand, but this is not recommended in */
37 /* cases where you would like to build several versions of the */
38 /* library from a single source directory. */
39 /* */
40 /* - You can put a copy of this file in your build directory, more */
41 /* precisely in `$BUILD/freetype/config/ftoption.h', where `$BUILD' */
42 /* is the name of a directory that is included _before_ the FreeType */
43 /* include path during compilation. */
44 /* */
45 /* The default FreeType Makefiles and Jamfiles use the build */
46 /* directory `builds/<system>' by default, but you can easily change */
47 /* that for your own projects. */
48 /* */
49 /* - Copy the file <ft2build.h> to `$BUILD/ft2build.h' and modify it */
50 /* slightly to pre-define the macro FT_CONFIG_OPTIONS_H used to */
51 /* locate this file during the build. For example, */
52 /* */
53 /* #define FT_CONFIG_OPTIONS_H <myftoptions.h> */
54 /* #include <freetype/config/ftheader.h> */
55 /* */
56 /* will use `$BUILD/myftoptions.h' instead of this file for macro */
57 /* definitions. */
58 /* */
59 /* Note also that you can similarly pre-define the macro */
60 /* FT_CONFIG_MODULES_H used to locate the file listing of the modules */
61 /* that are statically linked to the library at compile time. By */
62 /* default, this file is <freetype/config/ftmodule.h>. */
63 /* */
64 /* We highly recommend using the third method whenever possible. */
