How to link a static cuda library to a cpp project in visual studio

Hi, I have built a simple cuda project in visual studio that works perfectly fine when it is compiled alone.
However I want to use it in a cpp project, so I’ve referenced the project in my cpp one and added the include folder and the dependencies files.
I have also changed the cuda project configuration type as a static library.

Here is a typical header file of the cuda project

// whatever.h
#pragma once 

#include <vector>
std::vector<double> doMath(const std::vector<double>& input);

and here a typical cu file of the cuda project

#include "whatever.h"

#include "cuda_runtime.h"
#include "device_launch_parameters.h"

__global__ void kernel(double* input, double* output)
// ...

void doMath(const std::vector<double>& input)
   double* dInput;
   cudaMalloc(&dInput, input.size() * sizeof(double));
   cudaMemcpy(dInput, input.begin(), input.size() * sizeof(double), cudaMemcpyHostToDevice);

   double* dOutput;
   cudaMalloc(&dOutput, input.size() * sizeof(double))

   kernel<<<1,1>>>(dInput, dOutput);
   std::vector<double> output(input.size());
   cudaMemcpy(output.begin(), dOutput, input.size() * sizeof(double), cudaMemcpyDeviceToHost);

  return output;

The main file of the cpp project looks like this

// main.cpp
#include <iostream>
#include <vector>
#include "whatever.h"

int main()
   std::vector<double> input = {0,1,2,3,4,5,6};
   std::vector<double> output = doMath(input);

   for(double o: output) std::cout << o << ' ';

   return 0;

Why do I get this error “error LNK2019: unresolved external symbol cudaMalloc” ?
Why isn’t it working, I haven’t use any cuda code in the header files.
How can I make this work ?
