# By default we don't want to allow mixing compilers for building different repositories, so we
# embed the initially chosen compilers into the toolchain.
# This is because on Windows compilers aren't easily mixed.
# We want to avoid that qtbase is built using cl.exe for example, and then for another repo
# gcc is picked up from %PATH%.
# The same goes when using a custom compiler on other platforms, such as ICC.
#
# There are a few exceptions though.
#
# When crosscompiling using Boot2Qt, the environment setup shell script sets up the CXX env var,
# which is used by CMake to determine the initial compiler that should be used.
# Unfortunately, the CXX env var contains not only the compiler name, but also a few required
# arch-specific compiler flags. This means that when building qtsvg, if the Qt created toolchain
# file sets the CMAKE_CXX_COMPILER variable, the CXX env var is ignored and thus the extra
# arch specific compiler flags are not picked up anymore, leading to a configuration failure.
#
# To avoid this issue, disable automatic embedding of the compilers into the qt toolchain when
# cross compiling. This is merely a heuristic, becacuse we don't have enough data to decide
# when to do it or not.
# For example on Linux one might want to allow mixing of clang and gcc (maybe).
#
# To allow such use cases when the default is wrong, one can provide a flag to explicitly opt-in
# or opt-out of the compiler embedding into the Qt toolchain.
#
# Passing -DQT_EMBED_TOOLCHAIN_COMPILER=ON will force embedding of the compilers.
# Passing -DQT_EMBED_TOOLCHAIN_COMPILER=OFF will disable embedding of the compilers.

CMake: Fix usage of cache variables in qt.toolchain.cmake We have some cache variables that are used in our qt.toolchain.cmake toolchain file, for example QT_CHAINLOAD_TOOLCHAIN_FILE. When CMake runs a configure test with try_compile, our toolchain file is included again, but only a restricted set of variables is available. Add the variables that are used in our internal toolchain file to CMAKE_TRY_COMPILE_PLATFORM_VARIABLES. This makes them visible for try_compile calls operating on source files. Also pass the variables via the environment to support try_compile calls that operate on whole projects.

CMake: Fix default architecture selection for macOS and iOS Before this change, we created a CMake toolchain file for iOS and macOS universal which propagated the initially configured CMAKE_OSX_ARCHITECTURES values to user projects. So if Qt was configured with 2 arches, configuring a CMake user project using the generated toolchain file would also build the user project targeting those 2 arches. The reason for this that the same toolchain file is used for configuring both Qt and users projects and we needed to ensure that other Qt repos are built with the same set of arches. That unfortunately led the multiple arches to carry over into user projects. This is different from qmake behavior which configured user projects with 1 arch only. Instead of the toolchain file explicitly setting CMAKE_OSX_ARCHITECTURES for all projects, save the initial list of arches into QT_OSX_ARCHITECTURES. Then if the toolchain file detects that we're building a Qt repo (by checking for the presence of QT_REPO_MODULE_VERSION) set CMAKE_OSX_ARCHITECTURES to QT_OSX_ARCHITECTURES to propagate the initial list of arches. For user projects we want to have some sensible defaults. For macOS projects, leave the decision of the architecture to build to CMake. For iOS Xcode projects, leave the decision to Xcode. For iOS Ninja projects, set the architecture to the first value of the architectures used when configuring Qt. As a side note this fixes an issue in our CI where we configured macOS Qt with 2 architectures and then tried to run CMake build tests for both architectures on a machine that doesn't have the universal SDK. This led to build failures. Because the CMake build tests act as regular user projects, now they are configured with a single architecture that is automtically detected by CMake.

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.

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.

CMake: Fix usage of cache variables in qt.toolchain.cmake We have some cache variables that are used in our qt.toolchain.cmake toolchain file, for example QT_CHAINLOAD_TOOLCHAIN_FILE. When CMake runs a configure test with try_compile, our toolchain file is included again, but only a restricted set of variables is available. Add the variables that are used in our internal toolchain file to CMAKE_TRY_COMPILE_PLATFORM_VARIABLES. This makes them visible for try_compile calls operating on source files. Also pass the variables via the environment to support try_compile calls that operate on whole projects.
