So, I tried applying those changes to my 1.57.0 version, along with the bcp
develop, and got a new error:

error: Unable to find file or target named
error:     '/boost/system//boost_system'
error: referred to from project at
error:     'libs/chrono/build'
error: could not resolve project reference '/boost/system'

Building the Boost C++ Libraries.

error: Unable to find file or target named
error:     '/boost/system//boost_system'
error: referred to from project at
error:     'libs/chrono/build'
error: could not resolve project reference '/boost/system'

Am I heading down a rabbit hole?  I'm okay with moving to bcp-develop, but
will that throw off the dependencies in the rest of my build's modules, if
they are from 1.57?
