This is particularly an issue on macOS, where de facto package manager Homebrew will install libraries that are compiled for the specific version of macOS that the build machine is running, rendering the wheels useless for any previous version. And brew will not install the right arch for cross compilation of Apple Silicon wheels.
For these reasons, it's strongly recommended to not use brew for native library dependencies. Instead, we recommend compiling the library yourself. If you compile in the [`CIBW_BEFORE_ALL`](options.md#before-all) step, cibuildwheel will have already set the appropriate `MACOSX_DEPLOYMENT_TARGET` env var, so the library will target the correct version of macOS.

For build steps, Homebrew is still a great resource - you can [look up the build formula](https://formulae.brew.sh/) and use that as a starting point.

### macOS: Passing DYLD_LIBRARY_PATH to delocate
macOS has built-in [System Integrity protections](https://developer.apple.com/library/archive/documentation/Security/Conceptual/System_Integrity_Protection_Guide/RuntimeProtections/RuntimeProtections.html) which limits the use of `DYLD_LIBRARY_PATH` and `LD_LIBRARY_PATH` so that it does not automatically pass to children processes. This means if you set `DYLD_LIBRARY_PATH` before running cibuildwheel, or even set it in `CIBW_ENVIRONMENT`, it will be stripped out of the environment before delocate is called.

### macOS: Library dependencies do not satisfy target MacOS
Since delocate 0.11.0 there is added verification that the library binary dependencies match the target macOS version. This is to prevent the situation where a wheel platform tag is lower than the actual minimum macOS version required by the library. To resolve this error you need to build the library to the same macOS version as the target wheel (for example using `MACOSX_DEPLOYMENT_TARGET` environment variable).
Alternatively, you could set `MACOSX_DEPLOYMENT_TARGET` in `CIBW_ENVIRONMENT` to correctly label the wheel as incompatible with older macOS versions.
Alternatively, you could set `MACOSX_DEPLOYMENT_TARGET` in `environment` to correctly label the wheel as incompatible with older macOS versions.
This error may happen when you install a library using a package manager like Homebrew, which compiles the library for the macOS version of the build machine. This is not suitable for wheels, as the library will only work on the same macOS version as the build machine. You should compile the library yourself, or use a precompiled binary that matches the target macOS version.
