Cannot find -I/usr/local/cudnn/include

I am currently working with Jetson TX2 with cuda 10.2. When I tried to compile the darknet, it show that:
./src/convolutional_layer.c:282:24: error: ‘CUDNN_CONVOLUTION_FWD_PREFER_FASTEST’ undeclared (first use in this function); did you mean ‘CUDNN_CONVOLUTION_BWD_FILTER_ALGO_3’?
int forward_algo = CUDNN_CONVOLUTION_FWD_PREFER_FASTEST;
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
CUDNN_CONVOLUTION_BWD_FILTER_ALGO_3
I can cat the version of cudnn version as 8.0.0 but it seems that we can’t find the -I/usr/local/cudnn/include and there’s no such directory of cudnn.
