CMake: Get toolchain file path from EMSDK env for Wasm user projects Try to to chainload the emscripten CMake toolchain file from the EMSDK env var if it is set, instead of requiring the user to explicitly specify a path to the file via QT_CHAINLOAD_TOOLCHAIN_FILE. The order in which the toolchain file is chainloaded becomes is as follows: 1) The initial toolchain file path that was specified when configuring qtbase is set written as the initial value of __qt_chainload_toolchain_file in qt.toolchain.cmake 2) If EMSDK env var is set, it overrides the value from 1) 3) If QT_CHAINLOAD_TOOLCHAIN_FILE cache var is supplied it overrides the value from 2) Whichever value ends up in __qt_chainload_toolchain_file is checked too see if the file exists. If it exists it gets included, if it doesn't, a warning is issued. This checking logic is a bit crude and should be improved and unified with the Android chainload checking, but the current change already improves the behavior for users of Qt.

CMake: Handle detection of linux-g++-32 mkspec If Qt is configured with -platform linux-g++-32 , make sure to add the -m32 compile options for all built targets. On 64 bit host OSes that provide both 32 and 64 bit libraries we need to exclude the 64 bit libraries from being picked up. The locations of the libraries are distro-specific. This change by default excludes the Ubuntu x86_64 libraries paths. Opt outs are provided, which when used, forces Qt builders to specify their own ignore paths in a custom CMake toolchain file. The compile option and default path exclusions are added to the Qt-generated CMake toolchain file as well, so they are reused when building other Qt repositories. Note that there is no foolproof way to tell CMake to ignore all x86_64 packages / libraries, even if CMake 3.23 CMAKE_IGNORE_PREFIX_PATH is used, because there might not be a single sysroot to exclude. Both x86 and x86_64 libraries can co-exist in the same sysroot, e.g in /usr One would have to list each package / library directory in CMAKE_IGNORE_PATH manually. Additionally, the PKG_CONFIG_LIBDIR environment variable is also set to Ubuntu specific prefixes, to ensure that pkg_check_modules -> pkg-config don't pickup x86_64 libraries.

# 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 building iOS projects with a single-arch Qt build Automatically set the CMAKE_OSX_SYSROOT and CMAKE_OSX_ARCHITECTURES values with the ones Qt was configured with, when configuring a user project with the Xcode generator and a single arch / sdk Qt build. This ensures that calling xcodebuild from the command line chooses the correct architecture and SDK when building the project. Allow to opt out of this behavior by passing QT_NO_SET_OSX_ARCHITECTURES and QT_NO_SET_OSX_SYSROOT.

CMake: Override simulator architecture to x86_64 for Xcode generator The simulator build of Qt for iOS is currently x86_64 only, instead of universal builds with an arm64 slice as well, since we don't support xcframeworks. This means we can't rely on Xcode's default simulator arch settings, which on an Apple Silicon Mac will be arm64. Instead we override the simulator arch, like we do for qmake.

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.
