[minizip] Is it really mandatory the use of minizip-ng compared to minizip provided by zlib?

Hi!

[Talking with my Debian Developer hat on]

I'm trying to package OCIO v2.3.2 in Debian and it seems like I'm forced to package minizip-ng tool as well because the building process won't pass the initial checks without that build dependency.
As far as I understand it, minizip-ng is just a simpler version of the minizip tool (now merged in zlib, already in Debian archives) so I'm wondering if it's not possible to use the "normal" minizip library as an alternative to the -ng version, maybe allowing the [Findminizip-ng](https://github.com/AcademySoftwareFoundation/OpenColorIO/blob/main/share/cmake/modules/Findminizip-ng.cmake) module to search for both, prioring the -ng version. That would allow me to upgrade the package in Debian quicker.

Thanks.

share/cmake/modules/Findminizip-ng.cmake と、依存関係を必要とする初期のビルドチェックから始めます。モジュールが minizip-ng と zlib が提供する minizip をどのように検索するかを比較し、そのうえで minizip-ng を優先して両方をサポートできるかどうかを判断します。互換性のある代替手段が利用可能な場合に minizip-ng を必須とせずに Debian パッケージングのビルドが通れば完了です。
