[MKL-DNN] Unable to compile on linux #628
Description
Hi,
I'm trying to set up the javacpp/mkl-dnn project so I can play with some changes that I need.
As a first step, I tried to compile javacpp/mkl-dnn as-is, without any changes. I cloned the javacpp-presets, and issued mvn install --projects .,mkl-dnn from the parent project directory.
After downloading and processing mkl-dnn and mklml-lib, the compilation fails here:

[ERROR] mvn <goals> -rf :mkl-dnnI've successfully compiled vanilla mkl-dnn, and my arch-linux is recent and updated and set up with all usually required compilation tools. MKL is also present system-wide.
Now, since bytedeco libraries are regularily released, I guess that there is something that I'm doing wrong, but after re-reading the documentation, I can't guess what.
It seems to me that the problem is that cppbuild.sh fails to create the externals directory and unpack mklml-lib tar there. But why can it be?
