#* 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 root FreeType sub-Makefile, usually *
#* named `freetype/lib/Makefile.lib.' 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>.' *
#* *
#* OBJ_DIR: The location where the compiled object(s) file will be *
#* placed. *
#* *
#* 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_IFLAGS: 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. *
#* *
#* FT_CC: The C compiler to use. *
#* *
#* *
#* It sets the following variables, which are used by the parent Makefile *
#* after the call: *
#* *
#* BASE_H: The list of base layer header files on which the rest *
#* of the library (i.e., drivers) rely. *
#* *
#* BASE_OBJ_S: The single-object base layer. *
#* BASE_OBJ_M: A list of all objects for a multiple-objects build. *
#* BASE_EXT_OBJ: A list of base layer extensions, i.e., components *
#* found in `freetype/lib/base' which are not compiled *
#* within the base layer proper. *
