#*     FTINIT_DRIVER_PATHS:  The list of include paths used to compile the  *
#*                           `ftinit' component which registers all font    *
#*                            drivers in the FT_Init_FreeType() function.   *
#*                                                                          *
#*     FTINIT_DRIVER_H:      The list of header dependencies used to        *
#*                           compile the `ftinit' component.                *
#*                                                                          *
#*     FTINIT_DRIVER_MACROS: The list of macros to be defined when          *
#*                           compiling the `ftinit' component.              *

#*  `Single-object compilation' means that each font driver is compiled     *
#*  into a single object file.  This is useful to get rid of all            *
#*  driver-specific entries.                                                *
#*                                                                          *
