OSX_ARCHITECTURES — CMake 4.3.0 Documentation

# OSX_ARCHITECTURES

Target specific architectures for macOS.

The `OSX_ARCHITECTURES` property sets the target binary architecture for targets on macOS (`-arch`). This property is initialized by the value of the variable `CMAKE_OSX_ARCHITECTURES` if it is set when a target is created. Use `OSX_ARCHITECTURES_<CONFIG>` to set the binary architectures on a per-configuration basis, where `<CONFIG>` is an upper-case name (e.g. `OSX_ARCHITECTURES_DEBUG`).
