exiv2: Update to 0.28.1

[alchymy]

Macports shows exiv2 @0.27.6_0, looks like there is now a 0.28.1 version. Can't see any other tickets on this. Need 0.28.1 for a stellarium build. Any way to get 0.28.1 into my current Macports install?

Thanks for the reminder; I do need to update that.

The exiv2 0.28.1 update is straightforward enough but the library's major version changes so everything that links with the library needs a rebuild. Let me check if there are any problems with those first.

Thanks!

There are a couple dozen ports that depend on exiv2. I only checked a handful of them on December 28, but half of those I checked did not build with this new version and need patches, so updating exiv2 is not straightforward and will require an extended concerted effort to identify and fix all of the problems at once, an effort which I'm not currently continuing.

Replying to alchymy:

Need 0.28.1 for a stellarium build.

Per #69170 exiv2 appears to be optional for stellarium and you can disable its use and thus prevent the build failure by using the CMake flag -DCMAKE_DISABLE_FIND_PACKAGE_exiv2=ON.
