write a proper waf check for the lib that uses conf.check_cfg and
uselib_store. You then can simply add the libs as deps to your target.

The conf.check_cfg must of course provide the proper LDFLAGS including
the rpath.

Alternatively you can setup the environment variables manually like this:

    if Options.options.libcephfs_dir:
        conf.env['CPPPATH_CEPHFS'] = Options.options.libcephfs_dir + '/include'
        conf.env['LIBPATH_CEPHFS'] = Options.options.libcephfs_dir + '/lib'

Ymmv! ;)
