Our internal build system sets the _ITERATOR_DEBUG_LEVEL value to 1 for the Debug builds. How could I specify the debug level when using --build-type=complete?

Below is a Powershell function that I use to build Boost libraries on Windows platforms.

function build_boost_libraries {
    $number_of_cores = (Get-CimInstance Win32_ComputerSystem).NumberOfLogicalProcessors
    $debug_level = "1"
    $prefix_dir = "$root_dir\src\vc140-x64\"
    ./bootstrap.bat --prefix="$prefix_dir" --with-libraries=chrono,thread,regex,filesystem,date_time,json,program_options,json,container,regex | Out-Null
    ./b2 --prefix="$prefix_dir" --build-dir="$build_dir" -j"$number_of_cores" --build-type=complete link=static link=shared threading=single threading=multi --layout=tagged --disable-icu --with-chrono --with-thread --with-date_time --with-filesystem --with-program_options --with-json --with-iostreams --with-atomic --with-container --with-regex cxxstd=14 define=_ITERATOR_DEBUG_LEVEL="$debug_level" install | Out-Null
}

Thanks,
