why do we need to link this file? We only miss mkldnn_version.h, right?

Earlier it was linked to the entire 3rdparty/mkldnn/include folder. However it does not contain mkldnn_version.h there. In this change, I only link to required files instead of linking to the entire folder.

Did you verify if it works? I remember mkldnn.h may depend on other header files in the original folder.

Yes, I could verify it works fine in my local branch.

make -j$(nproc)
export LD_LIBRARY_PATH=/usr/local/cuda/lib:$LD_LIBRARY_PATH
pip install --no-cache-dir horovod

Here is the files in my include:

(mxnet) ubuntu@ip-172-31-7-88:~/src/mxnet$ ls include/mkldnn/
mkldnn.h  mkldnn_version.h

I see the including chain is: ndarray.h -> mkldnn.hpp -> mkldnn.h -> mkldnn_types.h and mkldnn_version.h.
