|

|
| + /* 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' */

| + /* 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, */
