Hey, this is the MXNet Label Bot.
Thank you for submitting the issue! I will try and suggest some labels so that the appropriate MXNet community members can help resolve it.
Here are my recommended labels: Installation, Build

Thanks for the issue. Looks like a problem finding a 3rd party package. When you cloned the repo did you use the --recursive flag?

Here's a link to the build from source instructions just in case.

Yes, --recursive flag was used.
And just now I did reproduce this bug on another computer with same software.

Don't try to build mxnet1.4.0, it is broken, I suggest you build mxnet1.3.1, it is still broken on windows 10, but unless with a lot of efforts, you can build it.

Please check this blog if you want to know how to build mxnet1.3.1 on windows.

@stereomatchingkiss , but I successfully build mxnet with ed83071 rev. With mkl, mkl blas, cuda, cudnn, opencv... However, I have not used it yet. Is it possible that the bugs will appear when it will be used?
And thanks for the great guide.

PS. Gtest I skip during the build.

but I successfully build mxnet with ed83071

It is a good news if you can build it on windows. How do you solve the issues of #13958 and #14343? I can build mxnet(1.3.1) with mkl too, problems is it always throw exception at runtime if you do the inference task by cpu(by gpu is fine).

ed83071 is a bit newer than 1.4.0, wonder if they fix the build issues on windows already?I am still waiting next stable release.

I did not make any changes to the code. As for Cmake, I do not remember exactly what changes I made to the configuration, but for sure nothing is critically important. Probably all of these issues were already fixed below or it was depend on VS version (my 2017, you as I understand 2015).

I don't use vc2017, since it always break support about cuda.
