| 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). |
