Build the Debian ${debian_version} package of the ${project} library.

If the build succeed the directory dist/debian${debian_version} will
contains the packages.

optional arguments:
    --help     show this help text
    --install  install the packages generated at the end of
               the process using 'sudo dpkg'
    --debian7  Simulate a debian7 system (fail-safe)
    --debian8  Simulate a debian 8 Jessie system
    --debian9  Simulate a debian 9 Stretch system
