BoostToolsetId.cmake

# - Translate CMake compilers to the Boost.Build toolset equivalents
# To build Boost reliably when a non-system compiler may be used, we
# need to both specify the toolset when running bootstrap.sh *and* in
# the user-config.jam file.
#
# This module provides the following functions to help translate between
# the systems:
#
#  function Boost_Get_ToolsetId(<var>)
#           Set var equal to Boost's name for the CXX toolchain picked
#           up by CMake. Only supports GNU and Clang families at present.
#           Intel support is provisional
#
