| [JPEG XL](https://en.wikipedia.org/wiki/JPEG_XL) || `WITH_JPEGXL` | _ON_ | Not supported. (see note) |
All libraries required to read images in these formats are included into OpenCV and will be built automatically if not found at the configuration stage. Corresponding `BUILD_*` options will force building and using own libraries, they are enabled by default on some platforms, e.g. Windows.
@note OpenJPEG have higher priority than JasPer which is deprecated. In order to use JasPer, OpenJPEG must be disabled.
@note (All) Only one library for each image format can be enabled(e.g. In order to use JasPer for JPEG 2000 format, OpenJPEG must be disabled).
@note (JPEG 2000) OpenJPEG have higher priority than JasPer which is deprecated.
@note (JPEG XL) OpenCV doesn't contain libjxl source code, so `BUILD_JPEGXL` is not supported.
@warning OpenEXR ver 2.2 or earlier cannot be used in combination with C++17 or later. In this case, updating OpenEXR ver 2.3.0 or later is required.
