This is not bug. It can improve by linking Intel MKL to DlibDotNet.Native.Dnn.dll.

Do I need to compile myself from the source code? Does the version installed from nuget.org use MKL?

Yes. Intel MKL are distributed from intel web site.
You must do user registration to download it.
And do compile DlibDotNet.Native.Dnn with Inte MKL.
The following is sample CMake command
set CURDIR=%cd%
set DIRLINK=build_cpu
mkdir %DIRLINK%
cd %DIRLINK%
set DLIBVER=19.15
set INTEL_MKL=D:/Works/Lib/Intel/Math Kernel Library/2019.0.117/Windows/windows
cmake -G "Visual Studio 15 2017 Win64" -T host=x64 ^
-DDLIB_PATH=D:/Works/Lib/DLib/%DLIBVER% ^
-DUSE_AVX_INSTRUCTIONS=ON ^
-DUSE_SSE2_INSTRUCTIONS=ON ^
-DUSE_SSE4_INSTRUCTIONS=ON ^
-DLIB_USE_BLAS=ON ^
-DBLAS_libiomp5md_LIBRARY="%INTEL_MKL%/compiler/lib/intel64_win/libiomp5md.lib" ^

-DBLAS_mkl_intel_thread_dll_LIBRARY="%INTEL_MKL%/mkl/lib/intel64_win/mkl_intel_thread_dll.lib" ^
..
cmake --build . --config %1
from dlibdotnet.

But it may be easy after you install intel MKL to system.
Because dlib provides find_blas.cmake to link Intel MKL.
https://github.com/davisking/dlib/blob/master/dlib/cmake_utils/find_blas.cmake
However, I did not use it, so I do not know it works.

I compiled DlibDotNet.Native.Dnn with MKL from source(19.15.0.20180916, commit-d7e71be), DlibDotnet and DlibDotNet.Native from nuget, but they didn't work with benchmark. The error message is as follows:
dotnet run -c Release -- "-m=Models"

If I use DlibDotNet.Native.Dnn from nuget, they are work well.
Is there a problem in my compile script?

Intel MKL library is not source code. It means that you must deploy Intel MKL library dll (or so) files.
I deployed the following libraries.
- libimalloc.dll
- libiomp5md.dll
- mkl_avx.dll
- mkl_avx2.dll
- mkl_avx512.dll
- mkl_avx512_mic.dll
- mkl_blacs_ilp64.dll
- mkl_blacs_intelmpi_ilp64.dll
- mkl_blacs_intelmpi_lp64.dll
- mkl_blacs_lp64.dll
- mkl_blacs_mpich2_ilp64.dll
- mkl_blacs_mpich2_lp64.dll
- mkl_blacs_msmpi_ilp64.dll
- mkl_blacs_msmpi_lp64.dll
- mkl_cdft_core.dll
- mkl_core.dll
- mkl_def.dll
- mkl_intel_thread.dll
- mkl_mc.dll
- mkl_mc3.dll
- mkl_msg.dll
- mkl_pgi_thread.dll
- mkl_rt.dll
- mkl_scalapack_ilp64.dll
- mkl_scalapack_lp64.dll
- mkl_sequential.dll
- mkl_tbb_thread.dll
- mkl_vml_avx.dll
- mkl_vml_avx2.dll
- mkl_vml_avx512.dll
- mkl_vml_avx512_mic.dll
- mkl_vml_cmpt.dll
- mkl_vml_def.dll
- mkl_vml_mc.dll
- mkl_vml_mc2.dll
- mkl_vml_mc3.dll
- tbb.dll
- tbbmalloc.dll
- tbbmalloc_proxy.dll
These should be <IntelMKLLibrary_dir>\Windows\windows\redist\intel64_win*.

Perhaps, we need not to deploy all these dll. But I do not know which binary is unnecessary.

It requires these libraries:
- libiomp5md.dll
- mkl_core.dll
- mkl_def.dll
- mkl_intel_thread.dll
from dlibdotnet.
