 20# The following variables (set by other Makefile components, in the
 21# environment, or on the command line) are used:
 22#
 23#   BUILD_DIR      The architecture dependent directory,
 24#                  e.g. `$(TOP_DIR)/builds/unix'.  Added to INCLUDES also.
 25#
 26#   OBJ_DIR        The directory in which object files are created.
 27#
 28#   LIB_DIR        The directory in which the library is created.
 29#
 30#   DOC_DIR        The directory in which the API reference is created.
 31#
 32#   INCLUDES       A list of directories to be included additionally.
 33#
 34#   DEVEL_DIR      Development directory which is added to the INCLUDES
 35#                  variable before the standard include directories.
 36#
 37#   CFLAGS         Compilation flags.  This overrides the default settings
 38#                  in the platform-specific configuration files.
 39#
 40#   FTSYS_SRC      If set, its value is used as the name of a replacement
 41#                  file for `src/base/ftsystem.c'.
 42#
 43#   FTDEBUG_SRC    If set, its value is used as the name of a replacement
 44#                  file for `src/base/ftdebug.c'.  [For a normal build, this
 45#                  file does nothing.]
 46#
 47#   FTMODULE_H     The file which contains the list of module classes for
 48#                  the current build.  Usually, this is automatically
 49#                  created by `modules.mk'.
 50#
 51#   BASE_OBJ_S
 52#   BASE_OBJ_M     A list of base objects (for single object and multiple
 53#                  object builds, respectively).  Set up in
 54#                  `src/base/rules.mk'.
 55#
 56#   BASE_EXT_OBJ   A list of base extension objects.  Set up in
 57#                  `src/base/rules.mk'.
 58#
 59#   DRV_OBJ_S
 60#   DRV_OBJ_M      A list of driver objects (for single object and multiple
 61#                  object builds, respectively).  Set up cumulatively in
 62#                  `src/<driver>/rules.mk'.
 63#
 64#   CLEAN
 65#   DISTCLEAN      The sub-makefiles can append additional stuff to these two
 66#                  variables which is to be removed for the `clean' resp.
 67#                  `distclean' target.
