### OpenCV single-core benchmarking

How can I benchmark OpenCV with parallelism disabled, i.e. on a single core of the CPU? Is this possible without rebuilding the libraries? Should I insert an #undef HAVE_PARALLEL_FRAMEWORK somewhere?

### Disable parallelism

How can I benchmark OpenCV on Windows (Visual Studio) with parallelism disabled, i.e. on a single core of the CPU? Is this possible without rebuilding the libraries? Should I insert an #undef HAVE_PARALLEL_FRAMEWORK somewhere?somewhere? I haven't noticed a CMake option to disable compilation with the Parallel Patterns Library, among other parallel frameworks.
