Disable ParModAuto cif required boost libs are not found. (#9171)

  - Instead of failing configuration completely when the required boost
    libraries are not found, simply disable ParModAuto and continue as it
    is an optional component anyway.

  - We can add a configuration option for this but seems like it is an
    overkill to add an option just for this at the moment.

  - We should probably handle the CPP runtime in a similar manner. Instead
    of requiring users to add yet another option to their configuration
    commandline.
