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.
Most library source codes required to read/write images in these formats are bundled into OpenCV and will be built automatically if not found at the configuration stage
(except for some codecs that require external libraries, e.g. JPEG XL and AVIF).
Corresponding BUILD_* options will force building and using the bundled libraries; they are enabled by default on some platforms, e.g. Windows.
@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.
@note (EXR) OpenCV 5 doesn't contain OpenEXR source code, so `BUILD_OPENEXR` is not supported.
@note (JPEG XL) OpenCV doesn't contain libjxl source code, so `BUILD_JPEGXL` is not supported. Users must provide a system-wide installation of libjxl.
@note (AVIF) OpenCV doesn't contain libavif source code, so `BUILD_AVIF` is not supported. Users must provide a system-wide installation of libavif.
@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.
