When cross-compiling with CMake, before this patch pkgconfig calls would find libraries which are part of the host system and not the target system. The current approach used is based of the discussion present in https://gitlab.kitware.com/cmake/cmake/-/merge_requests/4478, and should be considered a temporary solution until the issue is properly addressed in upstream CMake.
