install it and follow the
[MKLDNN_README](https://github.com/apache/incubator-mxnet/blob/master/MKLDNN_README.md)

from source. v0.2.19 is the most recent version that ships with binaries.
Contributions of more recent binaries would be appreciated.

installed location, and `C:\incubator-mxnet` is the location of the source code
you just cloned in the previous step.
4. Create a build dir using the following command and go to the directory, for
example:
```
-mkdir C:\build
-cd C:\build
