MKLINC-NOTFOUND or MKLLIB-NOTFOUND are not found

[portgasray]

Env:

• version: 2019_R3
• ubuntu 18.04

I met this error when building inference engine after cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local -DGEMM=MKL -DMKLROOT=/usr/local/lib/mklml -DENABLE_MKL_DNN=ON -DENABLE_CLDNN=ON ..
I already updated the submodule and performed install_dependencies.sh.

Here is the output (part)

Hello, cmake searches for libmklml_gnu.so and libmklml_intel.so libraries in the /lib folder.
Could you check if these files are present in the /usr/local/lib/mklml/lib folder?

there is no /usr/local/lib/mklml/lib or /usr/local/lib/mklml

[asuhov]

You specified this path in the cmake command: -DMKLROOT=/usr/local/lib/mklml

To build the inference engine with MKL, please download MKL package at https://github.com/intel/mkl-dnn/releases/download/v0.19/mklml_lnx_2019.0.5.20190502.tgz and specify a path to unpacked MKL with the include and lib folders in the -DMKLROOT parameter.

[portgasray]

thank you, I had already passed compiling dldt!

[portgasray]

I remembered that I used the official install_gui , then passed!

I have similar issue but on windows. I'm trying to build the lib with this command:
cmake -G "Visual Studio 16 2019" -A x64 -DCMAKE_BUILD_TYPE=Release -DGEMM=MKL -DENABLE_MKL_DNN=ON -DMKLROOT=../dnnl_win_1.2.0_cpu_tbb ..
where ../dnnl_win_1.2.0_cpu_tbb is a folder which contains 1.2.0 version of mkl-dnn with include and lib dir both present.

@portgasray I meet the same problem as you, but I confused how you solve the problem?
