This folder contains libraries and headers of a few very popular still image codecs
used by imgcodecs module.
The libraries and headers are preferably to build Win32 and Win64 versions of OpenCV.
On UNIX systems all the libraries are automatically detected by configure script.
In order to use these versions of libraries instead of system ones on UNIX systems you
should use BUILD_<library_name> CMake flags (for example, BUILD_PNG for the libpng library).

                      Refer to [LICENSE.md](libjpeg-turbo/LICENSE.md) for a roll-up of license terms.

                      Site: https://github.com/libjpeg-turbo/libjpeg-turbo
                      API is compatible with original libjpeg.

                      WITH_JPEG CMake option must be ON to add libjpeg or libjpeg-turbo support to imgcodecs.
                      BUILD_JPEG=ON selects libjpeg-turbo by default (since OpenCV 3.4.2).
                      Enable BUILD_JPEG_TURBO_DISABLE=ON to force using of libjpeg (this option is removed in OpenCV 4.0).
                      SIMD instructions are enabled by default. Use ENABLE_LIBJPEG_TURBO_SIMD to control SIMD instructions.
