#* IMPORTANT NOTE: This Makefile is intended for GNU Make! *
#* If you provide Makefiles for other make utilities, *
#* please place them in `freetype/lib/arch/<system>'. *
#* *
#* *
#* This file is to be included by the FreeType Makefile.lib, located in *
#* the `freetype/lib' directory. Here is the list of the variables that *
#* must be defined to use it: *
#* *
#* *
#* BASE_DIR: The location of the base layer's directory. This is *
#* usually `freetype/lib/base'. *
#* *
#* ARCH_DIR: The location of the architecture-dependent directory. *
#* This is usually `freetype/lib/arch/<system>'. *
#* *
#* DRIVERS_DIR: The location of the font driver sub-dirs, usually *
#* `freetype/lib/drivers'. *
#* *
#* OBJ_DIR: The location where the compiled object(s) file will be *
#* placed. *
#* *
#* BASE_H: A list of pathnames to the base layer's header files on *
#* which the driver depends. *
#* *
#* FT_CFLAGS: A set of flags used for compilation of object files. *
#* This contains at least the include paths of the arch *
#* and base directories + optimization + warnings + ANSI *
#* compliance. *
#* *
#* FT_IFLAG: The flag used to specify an include path on the *
#* compiler command line. For example, with GCC, this is *
#* `-I', while some other compilers use `/i=' or `-J', *
#* etc. *
#* *
#* FT_OBJ: The suffix of an object file for the platform; can be *
#* `o', `obj', `coff', `tco', etc. depending on the *
#* platform. *
#* *
#* *
#* It also updates the following variables defined and used in the main *
#* Makefile: *
#* *
#* DRV_OBJ_S: The list of driver object files in *
#* single-object mode. *
#* *
#* DRV_OBJ_M: The list of driver object files in *
#* multiple-objects mode. *
#* *
#* 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. *
#* *
