# # FreeType build system -- top-level sub-Makefile # # Copyright 1996-2000, 2001, 2003, 2006 by # David Turner, Robert Wilhelm, and Werner Lemberg. # # This file is part of the FreeType project, and may only be used, modified, # and distributed under the terms of the FreeType project license, # LICENSE.TXT. By continuing to use, modify, or distribute this file you # indicate that you have read the license and understand and accept it # fully. # 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 `PROJECT/builds/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 `PROJECT/builds/PROJECT.mk', used to build # the library. # # See the comments in `builds/detect.mk' and `builds/PROJECT.mk' for more # details on host platform detection and library builds. .PHONY: all setup distclean modules # The `space' variable is used to avoid trailing spaces in defining the # `T' variable later. # empty := space := $(empty) $(empty) # The main configuration file, defining the `XXX_MODULES' variables.
