   7 # ACX_CONFIGURE_DIR(SRC-DIR-NAME, BUILD-DIR-NAME, EXTRA-ARGS)
   8 # ---------------------------
   9 #
  10 # Configure a subdirectory.  This is an alternative to
  11 # AC_CONFIG_SUBDIRS that allows pointing the source directory
  12 # somewhere else.  The build directory is always a subdirectory of the
  13 # top build directory.  This is heavilly based on Autoconf 2.64's
  14 # _AC_OUTPUT_SUBDIRS.
  15 #
  16 # Inputs:
  17 #   - SRC-DIR-NAME is the source directory, relative to $srcdir.
  18 #   - BUILD-DIR-NAME is `top-build -> build'
  19 #   - EXTRA-ARGS is an optional list of extra arguments to add
  20 #     at the end of the configure command.
