For example, * * #define FT_CONFIG_OPTIONS_H * #include * * 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.
