[Boost-build] How to resolve Boost error: Candidate function not viable: expects an l-value for 1st argument

Hello,

I am trying to resolve this error: "5. Candidate function [with LoggerT =
boost::log::v2s_mt_posix::sources::severity_logger_mt<boost::log::v2s_mt_posix::trivial::severity_level>]
not viable: expects an l-value for 1st argument".

This error results in the inability to use the function "make_record_pump",
in my .cxx file, because "make_record_pump" is not recognized as a function
due to the previous error.

I am attempting to compile this project on Xcode 10.2, after building the
project with the newest version of CMake.  I have built boost
(version 1.69.0) and installed the dynamic libraries with homebrew.

Additionally, I have attached a series of screenshots to help portray this
issue, and if there might be any more information I could provide, please
let me know.

Thank you,
Austin Tapp
