How to add MKL with TBB threading to application that uses TBB under Visual Studio?

I have installed IntelSWTools 2017.4:
c:\Program Files (x86)\IntelSWTools\compilers_and_libraries\windows

My application uses TBB:
Release(/MD): tbb\lib\intel64\vc12\tbb.lib -> redist\intel64\tbb\vc12\tbb.dll
Debug(/MDd): tbb\lib\intel64\vc12\tbb_debug.lib -> redist\intel64\tbb\vc12\tbb_debug.dll

How to add MKL with TBB threading (so that there would be only one TBB instance) to application that uses TBB?

The problem is that mkl_tbb_thread_dll.dll (as I understand) linked with:
tbb\lib\intel64\vc_mt\tbb.lib -> redist\intel64\tbb\vc_mt\tbb.dll
which is different from what my application uses.

Is redist\intel64\tbb\vc_mt\tbb.dll for mkl_tbb_thread_dll.dll can be changed to redist\intel64\tbb\vc12\tbb.dll ?
If yes how to be with Debug build (somehow rename redist\intel64\tbb\vc12\tbb_debug.dll to tbb.dll)?

It seems there were discussion about the issue. As i recalled, you should be able to link the wanted tbb library with mkl_tbb_thread.lib .

vc_mt folder contains dlls which are statically linked to VC runtime. If you want to use the other tbb tied with MSVS version and runtime library., please try ,

if with Release(/MD)

Under Configuration Properties > linker > General Additional Directory. add the wanted tbb path : tbb\lib\intel64\vc12
add redist\intel64\tbb\vc12\ in your system environment variable PATH.
reopen your MSVS and recompiled your exe.

Here i assume you are link MKL manually. If you are link MKL Automatically. (please switch it ) and follow the instruction in manually parts.

and please let us know if any issues.

Thanks for help,

Thanks for help,
link with mkl_tbb_thread.lib (instead of mkl_tbb_thread_dll.lib) solves my issue.
