  # This sub-Makefile is in charge of detecting the current platform.  It sets
  # the following variables:
  #
  #   BUILD_DIR    The configuration and system-specific directory.  Usually
  #                `freetype/builds/$(PLATFORM)' but can be different for
  #                custom builds of the library.
  #
  # The following variables must be defined in system specific `detect.mk'
  # files:
  #
  #   PLATFORM     The detected platform.  This will default to `ansi' if
  #                auto-detection fails.
  #   CONFIG_FILE  The configuration sub-makefile to use.  This usually depends
  #                on the compiler defined in the `CC' environment variable.
  #   DELETE       The shell command used to remove a given file.
  #   COPY         The shell command used to copy one file.
  #   SEP          The platform-specific directory separator.
  #   COMPILER_SEP The separator used in arguments of the compilation tools.
  #   CC           The compiler to use.
  #
  # You need to set the following variable(s) before calling it:
  #
  #   TOP_DIR      The top-most directory in the FreeType library source
  #                hierarchy.  If not defined, it will default to `.'.
  
  # Set auto-detection default to `ansi' resp. UNIX-like operating systems.
  #
  PLATFORM     := ansi
  DELETE       := $(RM)

  # We define the BACKSLASH variable to hold a single back-slash character.
  # This is needed because a line like
  #
  #   SEP := \
  #
  # does not work with GNU Make (the backslash is interpreted as a line
  # continuation).  While a line like
  #
  #   SEP := \\
  #
  # really defines $(SEP) as `\' on Unix, and `\\' on Dos and Windows!
