With clang 16 and libcxx this is causig build error such as:
/usr/include/exiv2/value.hpp:54:17: error: no template named 'auto_ptr' in namespace 'std'; did you mean simply 'auto_ptr'?
        typedef std::auto_ptr<Value> AutoPtr;
Reverting upstream commit https://gitlab.gnome.org/GNOME/gexiv2/-/commit/2eb5c2c9ac1d36bee7089117e1f4825162a9409d
helps solve them for now.

There is on going work for exiv2-0.28
