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).
