# 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/builds/detect.mk'. They are in charge of detecting
# the current platform.
1999-12-17 00:11:37 +01:00
#
# 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/builds/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.
