For convenience, it's possible to use the ACTS build system to build the minimum required version of boost (currently 1.71.0). No source is bundled here, and if requested via "-DACTS_USE_SYSTEM_BOOST=OFF", only the filesystem, program_options, and test libraries will be built.

Warning: during installation, the built boost libraries will be installed alongside the ACTS libraries, with a version suffix. This location may be known to the system linker.
