Makefile build against official MKL and TBB possible?

[emmenlau]

Describe the bug I'd like to build DAAL for the standard CPU (no FPGA or GPU needed). I already have the Intel oneAPI Base Toolkit in my build and would like to build DAAL against that for MKL and TBB. When I try to build, it will not use the MKL from the oneAPI Base Toolkit. Would it be possible to support that, instead of the daal-specific MKL that is a binary download from Dependencies?

Environment:

• OS: Ubuntu 20.04 x86_64, Windows VS2019, macOS 11.6
• Compiler: Linux Clang 14.0.1, Visual Studio 2019 with ClangCl, Apple Clang from XCode 12

I have managed to change the makefile so that it will find TBB from my oneAPI installation. However this does not lead to a successful build, due to problems with linking TBB. It seems that oneDAL tries to link the static TBB when building a oneDAL DLL:

Anyone?

In general there are no plans to support build against MKL at the moment. In theory this would be possible - our fpk lib is subset of mkl functions with added prefix, so having some tool that would extract required functions and adding prefix would create similar fpk lib. Although there is also non mkl functions in fpk lib
