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).
