/* 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. */ | |
