"function is not an element of std" when using cppimport

I want to use this Github Repo: https://github.com/zekyll/OMPEval to get the equity of ranges. I also want to use this cpp code in my main python code, so I am trying to import my cpp code, which uses this github repo, into my main python code. Because I am still just trying out if the code works, I use python in cmd (on my windows 10 machine), so my code looks like this in the command line:

import cppimport.import_hook
import Scoring

Where Scoring is the main cpp file.

Scoring.cpp

//cppimport

/*
<%
setup_pybind11(cfg)
%>
*/

#include <omp/EquityCalculator.h>

#include "Scoring.h"

#include <array>
#include <vector>
#include <iostream>
#include <tuple>
#include <algorithm>

#include <iostream>
#include <algorithm>
#include <random>
#include <iterator>

#include <pybind11/pybind11.h>

#include <pybind11/stl.h>
#include <pybind11/complex.h>
#include <pybind11/functional.h>
#include <pybind11/chrono.h>


namespace py = pybind11;
using namespace pybind11::literals;


// here is a bunch of crap from my previous attempts trying to get a different repo working but it is unnecessary as I am not using it anymore


double montecarlo_omp(){
    omp::EquityCalculator eq;
    std::vector<omp::CardRange> ranges{"QQ+,AKs,AcQc", "A2s+", "random"};
    uint64_t board = omp::CardRange::getCardMask("2c4c5h");
    uint64_t dead = omp::CardRange::getCardMask("Jc");
    double stdErrMargin = 2e-5; // stop when standard error below 0.002%
    auto callback = [&eq](const omp::EquityCalculator::Results& results) {
        std::cout << results.equity[0] << " " << 100 * results.progress
                << " " << 1e-6 * results.intervalSpeed << std::endl;
        if (results.time > 5) // Stop after 5s
            eq.stop();
    };
    double updateInterval = 0.25; // Callback called every 0.25s.
    unsigned threads = 0; // max hardware parallelism (default)
    eq.start(ranges, board, dead, false, stdErrMargin, callback, updateInterval, threads);
    eq.wait();
    auto r = eq.getResults();
    std::cout << std::endl << r.equity[0] << " " << r.equity[1] << " " << r.equity[2] << std::endl;
    std::cout << r.wins[0] << " " << r.wins[1] << " " << r.wins[2] << std::endl;
    std::cout << r.hands << " " << r.time << " " << 1e-6 * r.speed << " " << r.stdev << std::endl;
}


PYBIND11_MODULE(Scoring, m) {
    m.def("montecarlo", &montecarlo_omp);
}

Now this code is just straight up from the README of the repo and I haven't changed anything. But when I run my cmd python code it throws this error:

(I am german so sorry for the german error)

In VS Code, which is the program I am writing the code in, it shows no problems and no red squiggles. I think it has something to do with the setup of cppimport.

I am using the latest cppimport, which I have intalled through pip. In my error message though, it also says right at the beginnig:

cl : Befehlszeile warning D9002 : Unbekannte Option "-std=c++11" wird ignoriert.
cl : Befehlszeile warning D9002 : Unbekannte Option "-fvisibility=hidden" wird ignoriert.

I would appreciate any further help! Thanks in Advance!
