pbrt question about unresolved external symbol

Question

Recently, I am stduying pbrt(physically based rendering). However, I have a question in using it in VS2019. I have cmaked the pbrt system(using the command "git clone --recursive https://github.com/mmp/pbrt-v3/"), and included it in VS. After I have written a simple test codes:

#define GOOGLE_GLOG_DLL_DECL
#include "core\pbrt.h"
#include "core\geometry.h"
#include "core\transform.h"
#include <iostream>
using namespace pbrt;
int main() {
    Transform T = Scale(2,3,5);
    pbrt::Vector3f a(1, 1, 1);
    pbrt::Vector3f b(2, 1, 1);
    pbrt::Vector3f c = a + b;
    pbrt::Point3f p0(0, 0, 0);
    pbrt::Ray r(p0, a);
    std::cout << r << std::endl;
}

the VS2019 gives lot of unresolved external symbol errors, which I did not show all of them here:

What is wrong with pbrt? I think I did not do anthing wrong when cmake, and what I sopposed to do now? Thank you very much for answering this question.
