Boost Log 1.65.1 Linking Issue

Good morning,

I am trying to create a logger that uses Boost Log. I was successful
getting my code to compile with 1.63.0, so I know that I am not too far off
of the mark. cmake/make throws a linking issues whenever I attempt to
create a sink:

                typedef sinks::synchronous_sink<
sinks::text_ostream_backend > text_sink;
     boost::shared_ptr< text_sink > sink = boost::make_shared< text_sink
>();

or create file sink

logging::add_file_log
     (
keywords::file_name = log_specs.log_file,
keywords::rotation_size = 10 * 1024 * 1024,
keywords::time_based_rotation = sinks::file::rotation_at_time_point(0, 0,
0),
keywords::filter = min_severity || severity >= file_severity,
keywords::format =
(
     expr::stream
<< expr::format_date_time<boost::posix_time::ptime>("TimeStamp",
"%Y-%m-%d_%H:%M:%S.%f")
         << ": [" << severity << "]"
         << expr::smessage
),
keywords::auto_flush = true //flush to file..
     );

My code will compile 95% and then produce the following:

Can someone please help? I have tried everything from trying to dynamically
and statically link. I've added both "log" and "log_setup" to the
find_packages in cmake and have also explicitly specified the locations of
those libraries as well.

Please let me know if there is anything else to try.

Thanks
