How could I compile with cuda/thrust library in cudamex?

Hi, I am trying to build a mex with thrust library with the below code. I got an error.

C:\Program Files\MATLAB\R2020b\extern\include\tmwtypes.h(815): fatal
error C1189: #error:  "This code must be compiled using a 2's
complement representation for signed integer values"

How to correct the error? Is there any thrust library example in Matlab?

% compile command
src = 'test.cu';
path1 =['-I' fullfile(cudaPath,'include\thrust')];
mexcuda(path1,src);
% mex(path1,src);

test.cu

#include "mex.h"
#include <thrust/device_vector.h>
void mexFunction(int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[])
{
    mxDouble *key = mxGetPr(prhs[0]);
    size_t N1 = mxGetM(prhs[0]);
    thrust::device_vector<int> d_a(key, key + N1);
}

(After searching on the internet, I found Matlab seems not support library thrust unfortunately.)

It seems matlab not supported thrust library as I searched on the internet.

The example could run well since 2021a.
