Detailed description

It is not possible to build OpenCV with multiple Intel SIMD instructions and run it on machines that do not support the latest SIMD set enabled.

This requires multiple versions of OpenCV shared libraries to be built and provided with projects that uses them.

Steps to reproduce

Build OpenCV enabling AVX2 or SSE4.2 and then run it on a machine that does not have these SIMD extensions.
