# 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 includes the rules found
# in `PROJECT/builds/detect.mk'. They are in charge of detecting the
# current platform.
#
# A summary of the detection is displayed, and the file `config.mk' is
# created in the current directory.
#
# - When invoked later, this Makefile includes the rules found in
# `config.mk'. This sub-Makefile defines some system-specific variables
# (like compiler, compilation flags, object suffix, etc.), then includes
# 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.
# First of all, check whether we have `$(value ...)'. We do this by testing
# for `$(eval ...)' which has been introduced in the same GNU make version.
