So, stitching together from your linked docs, something like (untested):

project
    : requirements
      [ requires cxx14_variable_templates cxx14_constexpr ]
      [ predef-require "BOOST_GCC == 0" or "BOOST_GCC_VERSION >= 60000" ]
      <define>BOOST_TEST_MODULE=Outcome
      <library>../../test/build//boost_unit_test_framework
    ;
