[BUG] Project no longer builds from source using Xcode 16.3

[heshuimu]

Describe the bug
Several issues occurred when building from source due to current wxWidgets version depends on old versions of zlib and libpng:
bulletphysics/bullet3#4607 (Not specific to wxWidgets, but the symptom was exactly the same)
wxWidgets/wxWidgets#24590

To Reproduce
On a Mac with Xcode 16.3 installed, build the CMake project as normally instructed.

Expected behavior
The project builds

Screenshots and/or logs
See two issues above.

Computer information:

• OS: macOS 15.4

I think it would be best to wait until wxWidgets fixes this upstream. In the meantime, does backdating to Xcode 16.2 work?
