#**************************************************************************
#*
#* FreeType demo utilities sub-Makefile
#*
#* This Makefile is to be included by "freetype/demo/Makefile". Its
#* purpose is to compile MiGS (the Minimalist Graphics Subsystem)
#*
#* It is written for GNU Make. Other make utilities are not
#* supported.. !!
#*
#*
#* The following variables must be defined :
#*
#* CFLAGS : C flags to use when compiling the utilities. This
#* must NOT include the '-c' flag used to specify a
#* simple compilation.
#*
#* IFLAG : include path flag. This is typically "-I" but some
#* compilers use a different convention..
#*
#* LFLAG : add link directory flag. Usually '-L' but could be
#* different..
#*
#* OBJ_DIR : target location of the object files
#*
#* UTIL_DIR : location of the utilities sources. I.e. this
#* directory (usually "freetype/demo/graph").
#*
#*
#* It also defines the following variables
#*
#* SIMPLE_UTILS : list of object files for the non-graphical utilities
#*
#* GRAPH_UTILS : all object files, including the graphics sub-system
#*
#* GRAPH_FLAGS : additional compile flags for graphical apps
#* GRAPH_LINK : additional link flags for graphical apps
#*
