#*  This file is to be included by the root FreeType sub-Makefile, usually  *

#*     BASE_DIR:  The location of the base layer's directory.  This is      *
#*                usually `freetype/lib/base.'                              *

#*     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.                          *
