OpenEXR v3.4.0 added OpenJPH as dependency: https://github.com/AcademySoftwareFoundation/openexr/releases/tag/v3.4.0

Integration with OpenEXR uses the OpenJPH open-source library. For ease in managing the dependency, the OpenEXR CMake configuration supports automatically fetching and building OpenJPH internally, or linking against an external installation.
