Currently our iOS CMake toolchain file sets the global
XCODE_EMIT_EFFECTIVE_PLATFORM_NAME property to OFF, to work
around a CMake issue regarding usage of object libraries in
conjunction with Xcode. The error was
The OBJECT library type may not be used for IMPORTED libraries under
Xcode with multiple architectures $(CURRENT_ARCH)
While this got rid of the error, it introduced a regression where
linking an executable against a static library in the same project
failed due to the library not being placed in a directory where Xcode
expects it to be.
clang: error: no such file or directory:
'~/build-untitled4-Qt_6_0_2_for_iOS/Debug/libuntitled4.a'
The actual library is created in Debug-iphoneos/libuntitled4.a
Note the -iphoneos suffix, which is related to the
EFFECTIVE_PLATFORM_NAME.
This could be further worked around by either explicitly setting the
library ARCHIVE_OUTPUT_DIRECTORY property in the project, or flipping
the value of the XCODE_EMIT_EFFECTIVE_PLATFORM_NAME to ON at the
end of the project. Both workarounds are not project-friendly.
In the mean time CMake got a fix for the original error
at https://gitlab.kitware.com/cmake/cmake/-/merge_requests/5771
which got released with CMake 3.20.0.
That was unfortunately not sufficient to remove our initial
workaround, because removing it would trigger a different
error at generation time
CMake Error:
Error evaluating generator expression:
$<TARGET_OBJECTS:Qt6::Quick_resources_1>
The evaluation of the TARGET_OBJECTS generator expression is only
suitable for consumption by CMake (limited under Xcode with multiple
architectures). It is not suitable for writing out elsewhere.
Fortunately, another fix landed in CMake 3.21.0 to address that
https://gitlab.kitware.com/cmake/cmake/-/merge_requests/6161
Because static builds (iOS) require CMake 3.21, with both of these
fixes we can now remove our workaround.
Even projects that set ARCHIVE_OUTPUT_DIRECTORY or flip
XCODE_EMIT_EFFECTIVE_PLATFORM_NAME to ON still continue to work
fine.
This also fixes installation of libraries, which also took into
account the effective platform name and thus caused a mismatch between
the expected output dir and the real one.

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.

that as well. Also, NDK r23b seems to have removed the part of code from

With this change, CMake will pass the value from the configure argument
-android-ndk-platform as -DANDROID_PLATFORM instead of
-DANDROID_NATIVE_API_LEVEL. Otherwise, if if -DANDROID_NATIVE_API_LEVEL

Previously when one wanted to use a cross-compiled Qt with a host Qt
installed in a non-default location, they'd have to provide both
QT_HOST_PATH and QT_HOST_PATH_CMAKE_DIR.
This change will now try to first check if ${QT_HOST_PATH}/lib/cmake
is a valid path on disk and use that. This is nicer to the user
because they don't need to specify 2 paths anymore.
Furthermore the path computation and sanity checks are now done after
any extra toolchain cmake files are loaded, to give an opportunity
to the files to set the paths first.
Finally, both variables need to be added to
__qt_toolchain_used_variables so they are passed along to try_compile
calls if the variables are specified manually.
Otherwise when the toolchain file is loaded by a try_compile project,
it will error out saying no host path found (as long as the initial
paths embedded in the toolchain are invalid).

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.

We want standalone tests added by qt_internal_add_test to be built as
universal executables, so we can build them on an intel machine and
run them on an ARM machine.
But CMake build tests will be built on the final machine that runs the
tests and it might lack a universal SDK. That's why they should be
built only targeting the architecture of the machine they're running
on.
Change the generated qt.tooclhain.cmake file to allow opting in or out
of building projects with the same architectures as Qt was configured
with.
Now standalone tests will be multi-arch, but CMake build tests will be

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.

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.
