#******************************************************************************
#*
#* FreeType build system - top-level Makefile
#*
#* This file is designed for GNU Make, do not use it with another Make tool.
#* It works as follows :
#*
#* - when invoked for the first time, this Makefile will include
#* the rules found in `freetype/config/detect.mk'. They are in charge
#* of detecting the current platform.
#*
#* A summary of the detection will be displayed, and the file `config.mk'
#* will be created in the current directory
#*
#*
#* - when invoked later, this Makefile will include the rules found in
#* `config.mk'. This sub-Makefile will define some system-specific
#* variables (like compiler, compilation flags, object suffix, etc..),
#* then include the rules found in `freetype/config/freetype.mk',
#* used to build the library.
#*
#* See the comments in `config/detect.mk' and `config/freetype.mk' for
#* more details on host platform detection and library builds..
