求助大佬，程序报这个错无法解析的外部符号 cudnnCreate，函数 main 中引用了该符号，怎么解决啊

include
include <cuda_runtime.h>
include <cudnn.h>

int main(int argc, char** argv)
{
// get gpu info
int numGPUs;
cudaGetDeviceCount(&numGPUs);
std::cout << “Found " << numGPUs << " GPUs.” << std::endl;
cudaSetDevice(0); // use GPU0
int device;
struct cudaDeviceProp devProp;
cudaGetDevice(&device);
cudaGetDeviceProperties(&devProp, device);
std::cout << “Compute capability:” << devProp.major << “.” << devProp.minor << std::endl;

cudnnHandle_t handle_;
cudnnCreate(&handle_);
std::cout << "Created cuDNN handle" << std::endl;

// create the tensor descriptor
cudnnDataType_t dtype = CUDNN_DATA_FLOAT;
cudnnTensorFormat_t format = CUDNN_TENSOR_NCHW;
int n = 1, c = 1, h = 1, w = 10;
int NUM_ELEMENTS = n * c * h * w;
cudnnTensorDescriptor_t x_desc;
cudnnCreateTensorDescriptor(&x_desc);
cudnnSetTensor4dDescriptor(x_desc, format, dtype, n, c, h, w);

// create the tensor
float* x;

// 创建 Unified Memory，这样cpu和memory都可以使用
cudaMallocManaged(&x, NUM_ELEMENTS * sizeof(float));
for (int i = 0; i < NUM_ELEMENTS; i++) x[i] = i * 1.00f;
std::cout << "Original array: ";
for (int i = 0; i < NUM_ELEMENTS; i++) std::cout << x[i] << " ";

// create activation function descriptor
float alpha[1] = { 1 };
float beta[1] = { 0.0 };
cudnnActivationDescriptor_t sigmoid_activation;
cudnnActivationMode_t mode = CUDNN_ACTIVATION_SIGMOID;
cudnnNanPropagation_t prop = CUDNN_NOT_PROPAGATE_NAN;
cudnnCreateActivationDescriptor(&sigmoid_activation);
cudnnSetActivationDescriptor(sigmoid_activation, mode, prop, 0.0f);

cudnnActivationForward(
    handle_,
    sigmoid_activation,
    alpha,
    x_desc,
    x,
    beta,
    x_desc,
    x
);

cudnnDestroy(handle_);
std::cout << std::endl << "Destroyed cuDNN handle." << std::endl;
std::cout << "New array: ";
for (int i = 0; i < NUM_ELEMENTS; i++) std::cout << x[i] << " ";
std::cout << std::endl;
cudaFree(x);
return 0;

}这个是代码
