| 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. |
