### Do prebuilt binaries of the version 2.4.3 for windows use TBB and Eigen?

Hi all. Do prebuilt binaries of the version 2.4.3 for windows use TBB and Eigen?

I've searched for TBB and parallel_for through files. Search for "parallel_for" has revealed several entries.

Search for TBB has brought to me files C:\opencv\build\x64\vc10\bin\opencv_core243.dll and C:\opencv\build\x64\vc10\bin\opencv_core243d.dll These binary files contain the following text:

....
Use TBB:            NO
Use Eigen:          NO
....


Overall, this part of the hexdump looks like a compiled in CMake configuration. However, I didn't find a function which would print it.

So, 2 questions. 1. Is the TBB and Eigen support is switched on by default? 2. Is there any function, which can print building parameters?
