  16 # This file is designed for GNU Make, do not use it with another Make tool!
  17 #
  18 # It works as follows:
  19 #
  20 # - When invoked for the first time, this Makefile includes the rules found
  21 #   in `PROJECT/builds/detect.mk'.  They are in charge of detecting the
  22 #   current platform.
  23 #
  24 #   A summary of the detection is displayed, and the file `config.mk' is
  25 #   created in the current directory.
  26 #
  27 # - When invoked later, this Makefile includes the rules found in
  28 #   `config.mk'.  This sub-Makefile defines some system-specific variables
  29 #   (like compiler, compilation flags, object suffix, etc.), then includes
  30 #   the rules found in `PROJECT/builds/PROJECT.mk', used to build the
  31 #   library.
  32 #
  33 # See the comments in `builds/detect.mk' and `builds/PROJECT.mk' for more
  34 # details on host platform detection and library builds.
  35
  36
  37 # First of all, check whether we have `$(value ...)'.  We do this by testing
  38 # for `$(eval ...)' which has been introduced in the same GNU make version.
