When I desided to build opencv library I have found out that there are number of compiler options available that does nearly the same - speed up algorithms. For example: TBB, IPP, CUDA, pthreads, Eigen2/Eigen3, OpenCL and others. Are there any benchmarks or known recommendations of what options are better than others and what caveats should be known?

It depends on your system needs. CUDA for example is relevant only if you have NVIDIA grpahic card, IPP only if you have the correct intel processor.
