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 ...)'.
