I just pushed a libmemcached.m4 into my branch - Brian should be merging
soon (I hope)
It has a macro AC_WITH_LIBMEMCACHED which you can use in your plugin file.
The macro will set ac_cv_have_memcached to yes if all is good. It also
defines an Automake conditional HAVE_MEMCACHED that you can use in your
makefile.
AND - it puts the flags into LIBMEMCACHED_CPPFLAGS and the
LIBMEMCACHED_LIBS.
So in your Makefile.am, you'll want to add something like:
AM_CPPFLAGS = ${GLOBAL_CPPFLAGS} ${LIBMEMCACHED_CPPFLAGS}
LDADD = ${LIBMEMCACHED_LIBS}
