[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.

从 share/cmake/modules/Findminizip-ng.cmake 以及要求该依赖项的初始构建检查开始。比较该模块如何搜索 minizip-ng 和 zlib 提供的 minizip，然后确定是否可以在优先使用 minizip-ng 的情况下同时支持两者。当兼容的替代方案可用时，Debian 打包构建无需 minizip-ng 即可通过，就表示完成。
