8 # ---------------------------
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
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.
