Description

For windows azure pipeline, now boost is not any more downloaded each time, but the one installed in the system is used. Currently, the version 1.72.0 of boost is used in the pipeline. In the future, if the maintainers of the pipeline update to a new boost version, it'll only necessary to change azure-pipelines.yml file.

This change should not change anything on currents developers, if of course they do not set the variable BOOST_ROOT_PIPELINE in their system.
