C++ 如何为VS2017配置AlgLib？

我正在编译一个alglib示例程序（有一些更改）：

我直觉地认为问题就在这里：

但我不能理解它的头绪。下一步是什么？

我遇到了一个类似（不确切）的问题，只需将编译好的cpp文件添加到我的项目中并将“包含在项目中”设置为true，问题就解决了

#pragma once


# include "Source\RFLearn.h" \\appropriate header for this simple .cpp program.
# include <LinAlg.h>
# include <stdint.h>
# include <chrono> // for in-game frame clock.


int RFLearn::test_function()
{
    alglib::real_2d_array a, b, c;
    int n = 2000;
    int i, j;
    double timeneeded, flops;

    // Initialize arrays
    a.setlength(n, n);
    b.setlength(n, n);
    c.setlength(n, n);
    for (i = 0; i<n; i++)
        for (j = 0; j<n; j++)
        {
            a[i][j] = alglib::randomreal() - 0.5;
            b[i][j] = alglib::randomreal() - 0.5;
            c[i][j] = 0.0;
        }

    // Set global threading settings (applied to all ALGLIB functions);
    // default is to perform serial computations, unless parallel execution
    // is activated. Parallel execution tries to utilize all cores; this
    // behavior can be changed with alglib::setnworkers() call.
    alglib::setglobalthreading(alglib::parallel);

    // Perform matrix-matrix product.
    flops = 2 * pow((double)n, (double)3);
    auto timer_start = std::chrono::high_resolution_clock::now();
    alglib::rmatrixgemm(
        n, n, n,
        1.0,
        a, 0, 0, 0,
        b, 0, 0, 1,
        0.0,
        c, 0, 0);
    auto timer_end = std::chrono::high_resolution_clock::now();
    auto duration = timer_end - timer_start;
    timeneeded = static_cast<double>(duration.count());

    // Evaluate performance
    printf("Performance is %.1f GFLOPS\n", (double)(1.0E-9*flops / timeneeded));

    return 0;
}
