# 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.
