libmemcached path?

Question

Trying to follow these instructions: (http://dev.mysql.com/doc/refman/5.1/en/ha-memcached-interfaces-mysqludf.html)

shell> tar zxf memcached_functions_mysql-1.1.tar.gz
shell> cd memcached_functions_mysql-1.1
shell> # If memcached library is not found, set LDFLAGS=-Llibrary_directory before next command.
shell> ./configure --with-mysql=/usr/local/mysql/bin/mysql_config

When I run:

sudo ./configure --with-mysql=/usr/lib64/mysql/mysql_config

I get this at the end of output:

checking for libmemcached >= 0.17... configure: error: libmemcached not found

So I tried to set LDFLAGS as instructed above but don't know the "library_directory" path.

How can I find it?

Update 1: As per response below. libmemcached IS installed:

You're missing libmemcached-devel, it probably needs headers too.
