# ACX_CONFIGURE_DIR(SRC-DIR-NAME, BUILD-DIR-NAME)
|
|
# ---------------------------
|
|
#
|
|
# Configure a subdirectory. This is an alternative to
|
|
# AC_CONFIG_SUBDIRS that allows pointing the source directory
|
|
# somewhere else. The build directory is always a subdirectory of the
|
|
# top build directory. This is heavilly based on Autoconf 2.64's
|
|
# _AC_OUTPUT_SUBDIRS.
|
|
#
|
|
# Inputs:
|
|
# - SRC-DIR-NAME is the source directory, relative to $srcdir.
|
|
# - BUILD-DIR-NAME is `top-build -> build'
