Certain platform-related variables, in this case UNIX, must be set in a
platform module, because they get cleared after the toolchain file is
loaded. Such platform modules live in upstream CMake, but there is none
yet for INTEGRITY. This manifests in an undefined UNIX variable and
"System is unknown to CMake" warnings for the project and every
configure test.
Add the CMake module "Platform/Integrity" in the cmake/platforms
directory. Add this directory to CMAKE_MODULE_PATH to let CMake load
Platform/Integrity when the toolchain file set CMAKE_SYSTEM_NAME to
"Integrity".
CMake's module directory takes precedence, when loading platform
modules. This is special for platform modules and different from the
documented behavior of CMAKE_MODULE_PATH and include().
In case the user wants to provide their own platform modules via
CMAKE_MODULE_PATH, they can instruct Qt to not add its path by setting
QT_AVOID_CUSTOM_PLATFORM_MODULES to ON.
Make sure that configure tests with project files also load the custom
platform module.

This reverts commit 657525965b.
The change relied on reading the last value of the
CMAKE_MINIMUM_REQUIRED_VERSION variable before one of the Qt packages
is found to use it for the version check.
Even if a user project has a cmake_minimum_required() right at
the beginning of the project with a supported version specified,
the first project() call which loads a CMake toolchain file could
contain another cmake_minimum_required() call with a lower
(unsupported) version and that version would be used for the check,
failing the project configuration.
The Android NDK ships such a toolchain file, which requires version
'3.6'.
Thus, relying on the last value of CMAKE_MINIMUM_REQUIRED_VERSION is
not robust enough.

Qt6Config.cmake calls cmake_minimum_required to ensure a recent enough
CMake version is used in projects.
That call does not set policies in the calling subdirectory scope,
because find_package introduces a new policy scope.
If a project using Qt has a 'cmake_minimum_required(VERSION 3.1)'
call and is configured with a recent CMake, many policies will
still be set to OLD.
One such policy is CMP0071 (Run AUTOMOC on GENERATED files). The
policy value is queried at generation time rather than at target
definition time, which means we can't influence the policy value
(e.g. inside the implementation of qt_add_executable for example)
The inability to influence the policy value for targets created by our
own CMake functions is unfortunate and can lead to issues (in the case
of the above policy to compilation / linker issues).
Record the version of the last cmake_minimum_required call before
the Qt packages are found and error out if the version is lower than
the minimum supported one.
A project can reduce the error into a warning by specifying a
-DQT_FORCE_MIN_CMAKE_VERSION_FOR_USING_QT_IN_CMAKE_MIN_REQUIRED=3.xyz
option when configuring the project.
If the option is used and build issues arise, no official support is
given.
All the CMake example projects shipped with Qt specify a minimum
version of 3.16 already (which is the minimum for shared Qt builds),
so it shouldn't be an issue to require that in other user projects as
well.
Implementation wise, we follow the existing pattern to record
what the minimum and computed versions for static and shared Qt
builds are at qtbase configure time.
These are then checked before the Qt6 or QtFoo packages are
find_package'd.

This change introduces new behavior to error out when configuring user
projects if the CMake version used is too old for Qt to work with.
The main motivator is the requirement of new CMake features to ensure
object libraries are placed in the proper place on the link line in
static builds.
The minimum CMake version is computed based on whether Qt was
configured as shared or static libraries.
At the moment the required versions for building and using Qt are the
same.
The minimum versions are defined in qtbase/.cmake.conf in the
following variables
QT_SUPPORTED_MIN_CMAKE_VERSION_FOR_BUILDING_QT_SHARED
QT_SUPPORTED_MIN_CMAKE_VERSION_FOR_BUILDING_QT_STATIC
QT_SUPPORTED_MIN_CMAKE_VERSION_FOR_USING_QT_SHARED
QT_SUPPORTED_MIN_CMAKE_VERSION_FOR_USING_QT_STATIC
Qt Packagers can disable the version check when configuring Qt
by setting
QT_FORCE_MIN_CMAKE_VERSION_FOR_BUILDING_QT and
QT_FORCE_MIN_CMAKE_VERSION_FOR_USING_QT.
In this case it is the packagers responsibility to ensure such a Qt
works correctly with the specified CMake version.
User projects can also set QT_FORCE_MIN_CMAKE_VERSION_FOR_USING_QT
to disable the version check. Then it's the project's developer
responsibility to ensure such a Qt works correctly.
No official support is provided for these cases.
Implementation notes.
The versions required to build Qt are stored in
QtBuildInternalsExtra.cmake
whereas the versions required to use Qt are stored in a new
QtConfigExtras.cmake.
Also the policy range variables stored in
QtBuildInternalsExtra.cmake are now regular variables instead of cache
variables, to properly allow overrides per-repository.

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.

When a CMake release introduces a new policy that affects most Qt
modules, it may be appropriate to make each module aware of that newer
CMake version and use the NEW policy without raising the minimum CMake
version requirement. To reduce the churn associated with making that
change across all Qt modules individually, this change allows it to be
updated in a central place (qtbase), but in a way that allows a Qt
module to override it in its own .cmake.conf file if required (e.g. to
address the issues identified by policy warnings at a later time). The
policies are modified at the start of the call to
qt_build_repo_begin().
For commands defined by the qtbase module, qtbase needs to be in
control of the policy settings at the point where those commands are
defined. The above mechanism should not affect the policy settings for
these commands, so the various *Config.cmake.in files must not specify
policy ranges in a way that a Qt module's .cmake.conf file could
influence.
Starting with CMake 3.12, policies can be specified as a version range
with the cmake_minimum_required() and cmake_policy() commands. All
policies introduced in CMake versions up to the upper limit of that
range will be set to NEW. The actual version of CMake being used only
has to be at least the lower limit of the specified version range.
This change uses cmake_minimum_required() rather than cmake_policy()
due to the latter not halting further processing upon failure.

Nevertheless the option is useful for testing how Qt builds with a

A counterpart change is needed in qt5 to ensure the minimum CMake

Ideally we would use the same 'check the CMake minimum version` code
in all our repositories, but that will cause lots of duplication because
we can't really find_package() the code and doing something like
include(../qtbase/foo.cmake) hardcodes assumptions about repo
locations.
So for now we don't bump the minimum version in child repo
cmake_minimum_required calls (qtsvg, qtdeclarative, etc).
Instead we record both the minimum supported version and the computed
minimum version (in case a different version was forced) in
QtBuildInternalsExtra.cmake.
Then we require qtbase's computed min version in
qt_build_repo_begin().
This won't set policies as cmake_minimum_required would, but at least
it propagates what minimum CMake version should be used for child
repos.
We might still have to bump the versions in child repos at some point.

If a consumer wants to cross-compile a Qt app, they need to provide
the host Qt path location.
When building Qt in the CI we embed the Qt host path into the
generated CMake toolchain file for convenient building of other Qt
modules.
But once Qt is built, packaged and installed on a user's machine, most
likely the Qt host path will not be the same. In such a case, if the
user wants to use the convenience toolchain, they should explicitly
provide the Qt host path via the QT_HOST_PATH and
QT_HOST_PATH_CMAKE_DIR variables.
Show an error message if the values are not provided or don't exist
on the file system.
It's possible that in the future the Qt installer will patch the
toolchain file, or provide additional info, to point to the host
Qt installation so that the user doesn't have to do it manually.
But until that's done, a friendly error message is a good way to
inform the user what they should do.

Public consumers of the qt toolchain file will most likely not have
their compilers in the same location where they were on the Qt build
machine.
Only set the compiler paths if none was set already, and the paths
actually exist.
This seems to become a trend in the generated toolchain file, and is
only a stop-gap solution.
A proper solution (two different toolchain files) may follow.

A previous change accidentally broke what we we set for

The QT_HOST_PATH variable should use an absolute path as it was
done before.
The QT_HOST_PATH_CMAKE_DIR variable incorrectly used the value of

Rather than force setting the apple sysroot and Qt host paths, first
check if they are not already defined on the command line and if they
aren't, check that the paths with which Qt was configured exist.
The goal of the patch is to not set invalid paths, like when using a
Qt built in the CI, which will have a different host path / sysroot
compared to what a user has locally.

qt_install_qml_files is removed because it's dead code.

mkspecs/features/qt.prf adds a dependency on the system threading
library if the Qt Core thread feature is enabled. Because qt.prf is
loaded by any public or internal Qt project, it's essentially a public
dependency for any Qt consumer.
To mimic that in CMake, we check if the thread feature is enabled, and
and set the Threads::Threads library as a dependency of Qt6::Platform,
which is a public target used by all Qt modules and plugins and Qt
consumers.
We also need to create a Qt6Dependencies.cmake file so we
find_package(Threads) every time find_package(Qt6) is called.
For the .prl files to be usable, we have to filter out some
CMake implementation specific directory separator tokens
'CMAKE_DIRECTORY_ID_SEP' aka '::@', which are added because we call
target_link_libraries() with a target created in a different scope
(I think).
As a result of this change, we shouldn't have to hardcode
Threads::Threads in other projects, because it's now a global public
dependency.

While trying to implement the 'host artifact reuse' Coin instructions
change, a bug surfaced where the qemu configurations didn't find
the host tools and instead tried to use the cross-compiled tools
while building qtbase, which failed due to not finding the
runtime linker (another unsolved issue).
Before the host artifact reuse change, the host tools were found
successfully.
The difference that caused the issue is that the target install prefix
was a direct subfolder of the host prefix.
host - /home/qt/work/qt/install
target - /home/qt/work/qt/install/target
Before the host reuse change the install prefixes were as follows
host - /home/qt/work/qt/install/host
target - /home/qt/work/qt/install/target
While looking for the Qt6CoreTools package, we temporarily set
CMAKE_FIND_ROOT_PATH and CMAKE_PREFIX_PATH to contain first
'/home/qt/work/qt/install' and then '/home/qt/work/qt/install/target'.
CMake then reroots the CMAKE_PREFIX_PATH values onto values in
CMAKE_FIND_ROOT_PATH, making an MxN list of prefixes to search.
Rerooting essentially means concatenating 2 paths, unless the
considered prefix is a subfolder of the root path.
What happened was that the first considered value was
'/home/qt/work/qt/install/home/qt/work/qt/install', a non-existent
location that gets discarded.
The second considered value was '/home/qt/work/qt/install/target.
The second value is the result of seeing that
'/home/qt/work/qt/install/target' is a subfolder of
'/home/qt/work/qt/install' and thus the root path is stripped.
All of this is done in cmFindPackageCommand::FindConfig() ->
cmFindCommon::RerootPaths.
The behavior above caused the target tools be found instead of the
host ones.
Before the host reuse change, both of the initial constructed prefixes
were discared due to them not existing, e.g.
'/home/qt/work/qt/install/target/home/qt/work/qt/install/target'
and '/home/qt/work/qt/install/host/home/qt/work/qt/install/host'
One of the later prefixes combined CMAKE_FIND_ROOT_PATH ==
'/home/qt/work/qt/install/host' + CMAKE_PREFIX_PATH == '/' resulting
in '/home/qt/work/qt/install/host/' and this accidentally found the
host tools package.
We actually stumbled upon this issue a while ago when implementing Qt
5.14 Android CMake support in 52c799ed44
That commit message mentions the fix is to add a "lib/cmake"
suffix to the PATHS option of find_package().
This would cause the subfolder => strip root behavior mentioned
above.
So finally the fix.
First, make sure not to append QT_HOST_PATH in the toolchain file,
there shouldn't be any need to do that, give that we temporarily set
it when looking for Tools packages.
Second, recreate the subdir scenario in the Qt toolchain file by
setting CMAKE_FIND_ROOT_PATH to the current (relocated) install
prefix as usual, but also setting CMAKE_PREFIX_PATH to a new value
poining to the CMake directory.
Aka '/home/alex/qt' and '/home/alex/qt/lib/cmake'.
Third, when a QT_HOST_PATH is given, save 2 paths in the generated Qt
toolchain: QT_HOST_PATH and QT_HOST_PATH_CMAKE_DIR. There are the host
equivalents of the target ones above. Use these values when looking
for host tools in Qt6CoreModuleDependencies.cmake, again facilitaing
the subdir behavior.
Note these are currently absolute paths and are not relocatable.
We'll have to figure out if it's even possible to make the host path
relocatable.
Finally as a cleanup, look for the Qt6HostInfo package in QtSetup
strictly in the given QT_HOST_PATH, so CMake doesn't accidentally find
a system Qt package.
