Can you use pkg_config for the zookeeper check?

You need something like this:

    if Options.options.with_zookeeper:
        conf.check_cfg(package='zookeeper', args='--cflags --libs',
                       msg='Checking for zookeeper', uselib_store="ZOOKEEPER")
        conf.CHECK_HEADERS('zookeeper_log.h', lib='zookeeper')

Cf source3/wscript, l. 1511 where we solve the same problem for glusterfs.

Hth!
