Possibly, it's related to the change in GCC 5+ versioning.
This was accommodated in Boost.Build in October 2018
that is, in Boost 1.69
(boostorg/build should use milestones for issues, IMO)

BTW, there are also CMake's issues in FindCMake.cmake
related to the compiler and architecture tag. So, you may have to
specify Boost_COMPILER and Boost_ARCHITECTURE hints
in order to help FindBoost.cmake recognise versioned names.

One of is what b2 --help says about --layout

"The default value is 'versioned' on Windows, and 'system' on Unix."
