I got error when I try to make caffe and type cmake ..:

My cudnn version is 8.6.0. In the newer cudnn versions, the version information has been moved from cudnn.h to cudnn_version.h. However, in older versions, the cudnn_version.h file does not exist. So if the cudnn_version.h file is not exist, the version information will be loaded from cudnn.h.
