CMake: Fix building multi-arch universal macOS Qt Use the same approach we use for iOS, which is to set multiple CMAKE_OSX_ARCHITECTURES values and let the clang front end deal with lipo-ing the final libraries. For now, Qt can be configured to build universal macOS libraries by passing 2 architectures to CMake, either via: -DCMAKE_OSX_ARCHITECTURES="x86_64;arm64" or -DCMAKE_OSX_ARCHITECTURES="arm64;x86_64" Currently we recommend specifying the intel x86_64 arch as the first one, to get an intel slice configuration that is comparable to a non-universal intel build. Specifying the arm64 slice first could pessimize optimizations and reduce the feature set for the intel slice due to the limitation that we run configure tests only once. The first specified architecture is the one used to do all the configure tests. It 'mostly' defines the common feature set of both architecture slices, with the excepion of some special handling for sse2 and neon instructions. In the future we might want to run at least the Qt architecture config test for all specified architectures, so that we can extract all the supported sub-arches and instruction sets in a reliable way. For now, we use the same sse2 hack as for iOS simulator_and_device builds, otherwise QtGui fails to link due to missing qt_memfill32_sse2 and other symbols. The hack is somewhat augmented to ensure that reconfiguration still succeeds (same issue happened with iOS). Previously the sse2 feature condition was broken due to force setting the feature to be ON. Now the condition also checks for a special QT_FORCE_FEATURE_sse2 variable which we set internally. Note that we shouldn't build for arm64e, because the binaries get killed when running on AS with the following message: kernel: exec_mach_imgact: not running binary built against preview arm64e ABI. Aslo, by default, we disable the arm64 slice for qt sql plugins, mostly because the CI provisioned sql libraries that we depend on only contain x86_64 slices, and trying to build the sql plugins for both slices will fail with linker errors. This behavior can be disabled for all targets marked by qt_internal_force_macos_intel_arch, by setting the QT_FORCE_MACOS_ALL_ARCHES CMake option to ON. To disble it per-target one can set QT_FORCE_MACOS_ALL_ARCHES_${target} to ON.

# Certain targets might have dependencies on libraries that don't have an Apple Silicon arm64
# slice. When doing a universal macOS build, force those targets to be built only for the
# Intel x86_64 arch.
# This behavior can be disabled for all targets by setting the QT_FORCE_MACOS_ALL_ARCHES cache
# variable to TRUE or by setting the target specific cache variable
# QT_FORCE_MACOS_ALL_ARCHES_${target} to TRUE.
#
# TODO: Ideally we'd use something like _apple_resolve_supported_archs_for_sdk_from_system_lib
# from CMake's codebase to parse which architectures are available in a library, but it's
# not straightforward to extract the library absolute file path from a CMake target. Furthermore
# Apple started using a built-in dynamic linker cache of all system-provided libraries as per
# https://gitlab.kitware.com/cmake/cmake/-/issues/20863
# so if the target is a library in the dynamic cache, that might further complicate how to get
# the list of arches in it.
