If still relevant, I have modified the code into a single header file that successfully compiles on Windows10 (VS19, C++20).
note: add the following library to link (e.g. proj-properties->linker->input: Additional Dependencies)
Ws2_32.lib

mainly supporting non-win32 headers pole.h & unistd.h...
below is the code for single-header tqdm.h:


//! this file was modified by chanangaza into a single-header file. it includes some adjustments to make it compile on Windows.

        Parameters
        ----------
        iterable  : iterable, optional
            Iterable to decorate with a progressbar.
            Leave blank to manually manage the updates.
        desc  : str, optional
            Prefix for the progressbar.
        total  : int, optional
            The number of expected iterations. If unspecified,
            len(iterable) is used if possible. As a last resort, only basic
            progress statistics are displayed (no ETA, no progressbar).
            If `gui` is True and this parameter needs subsequent updating,
            specify an initial arbitrary large positive integer,
            e.g. int(9e9).
        leave  : bool, optional
            If [default: True], keeps all traces of the progressbar
            upon termination of iteration.
        file  : `io.TextIOWrapper` or `io.StringIO`, optional
            Specifies where to output the progress messages
            [default: sys.stderr]. Uses `file.write(str)` and `file.flush()`
            methods.
        ncols  : int, optional
            The width of the entire output message. If specified,
            dynamically resizes the progressbar to stay within this bound.
            If unspecified, attempts to use environment width. The
            fallback is a meter width of 10 and no limit for the counter and
            statistics. If 0, will not print any meter (only stats).
        mininterval  : float, optional
            Minimum progress update interval, in seconds [default: 0.1].
        maxinterval  : float, optional
            Maximum progress update interval, in seconds [default: 10.0].
        miniters  : int, optional
            Minimum progress update interval, in iterations.
            If specified, will set `mininterval` to 0.
        ascii  : bool or str, optional
            If unspecified or False, use unicode (smooth blocks) to fill
            the meter.
            The fallback is to use ASCII characters " 123456789#".
        disable  : bool, optional
            Whether to disable the entire progressbar wrapper
            [default: False].
        unit  : str, optional
            String that will be used to define the unit of each iteration
            [default: it].
        unit_scale  : bool, optional
            If set, the number of iterations will be reduced/scaled
            automatically and a metric prefix following the
            International System of Units standard will be added
            (kilo, mega, etc.) [default: False].
        dynamic_ncols  : bool, optional
            If set, constantly alters `ncols` to the environment (allowing
            for window resizes) [default: False].
        smoothing  : float, optional
            Exponential moving average smoothing factor for speed estimates
            (ignored in GUI mode). Ranges from 0 (average speed) to 1
            (current/instantaneous speed) [default: 0.3].
        bar_format  : str, optional
            Specify a custom bar string formatting. May impact performance.
            If unspecified, will use '{l_bar}{bar}{r_bar}', where l_bar is
            '{desc}{percentage:3.0f}%|' and r_bar is
            '| {n_fmt}/{total_fmt} [{elapsed_str}<{remaining_str},
{rate_fmt}]'
            Possible vars: bar, n, n_fmt, total, total_fmt, percentage,
            rate, rate_fmt, elapsed, remaining, l_bar, r_bar, desc.
        initial  : int, optional
            The initial counter value. Useful when restarting a progress
            bar [default: 0].
        position  : int, optional
            Specify the line offset to print this bar (starting from 0)
            Automatic if unspecified.
            Useful to manage multiple bars at once (eg, from threads).
        gui  : bool, optional
            WARNING: internal parameter - do not use.
            Use tqdm_gui(...) instead. If set, will attempt to use
            matplotlib animations for a graphical output [default: False].
        Returns

        out  : decorated iterator.
