+ /* 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. */
