dnl @synopsis AX_SOCI
dnl 
dnl This macro tries to find Soci C API header and library locations.
dnl
dnl We define the following configure script flags:
dnl
dnl		--with-soci: Give prefix for both library and headers, and try
dnl			to guess subdirectory names for each.  (e.g. Tack /lib and
dnl			/include onto given dir name, and other common schemes.)
dnl		--with-soci-lib: Similar to --with-soci, but for library only.
dnl		--with-soci-include: Similar to --with-soci, but for headers
dnl			only.
