Getting back to 11.0 macOS deployment target in libcxx 17.0.6 #157

Hi, thanks for all the work you guys are putting into this!

As a newbie user, I'm naïvely trying to build Python wheels à la cibuildwheel but using conda as the environment. I'm aware of this discussion and Isuru's suggestion. I'm going down this foolish route thanks to Boost.Python...

All my conda libraries have 11.0 deployment targets on arm64 (as cibuildwheel likes it) except for libcxx 17.0.6 he7857fb_1, which is now on 12.0. This upsets delocate-wheel.

I've looked at #154 for more insight. If I try to install the alternate version (h5a255bb_1) with label libcxx_macos_lt_12, conda complains that package libcxx-17.0.6-h5a255bb_1 has constraint __osx <12 conflicting with __osx-13.6.7-0. This is fair enough, although I had hoped that this label would refer to deployment target and not actual OS version.

Am I using the libcxx_macos_lt_12 label wrong?

The alternative is to just grin and bear the minimum OS version of 12.0 in my wheels (not so bad either).

Or maybe this is a complete wild goose chase? 😅

Excellent!

Think you need the build/number 0 of 17.0.6 for macOS 10.13

Thanks, that's exactly what I ended up doing. I'm glad to hear it's a temporary issue.
