10 # ---------------------------
12 # Configure a subdirectory. This is an alternative to
13 # AC_CONFIG_SUBDIRS that allows pointing the source directory
14 # somewhere else. The build directory is always a subdirectory of the
15 # top build directory. This is heavilly based on Autoconf 2.64's
19 # - SRC-DIR-NAME is the source directory, relative to $srcdir.
20 # - BUILD-DIR-NAME is `top-build -> build'
