------------------------------------
1. Create folder for build (for example `<home-dir>/my-hal-build`)
2. Go to created folder and run cmake: `cmake <opencv-src>/samples/hal/slow_hal`
2. Go to the created folder and run cmake: `cmake <opencv-src>/samples/hal/slow_hal`
3. Run make
After build you will find static library in the build folder: `libslow_hal.a`

3. Run make (or `make opencv_perf_core` to build the demonstration test executable only)
4. After build you can run the tests and verify that some functions are slower now:
```
./bin/opencv_perf_core --gtest_filter=*bitwise_and*
