After the update to the CMake based build system the ability to
generate pkgconfig files, like it was with QMake, was lost.
This patch adds pkgconfig generation again via a new internal command
named qt_internal_export_pkg_config_file.
The functionality of this command consists in checking if the target
is internal. Then gets the compile definitions. It performs a search
for dependencies that is somewhat similar to
qt_get_direct_module_dependencies, although it won't recurse down for
more deps. Each dependency is then again, checked if it's internal or
has a public interface. Later these deps get deduplicated and lastly
a pkgconfig file is filled.
The resulting pkgconfig files of many of the Qt6 packages were
validated via invocations of `pkg-config --validate` and
`pkg-config --simulate` commands and later used to build local
projects plus tests that use the pkg-config provided details at
compilation time.
Although it has some limitations, with qt_internal_add_qml_module if
it specifies non-public deps these won't be listed and with non-Qt
requirements, notably in static builds, not being appended to the
PkgConfig file.

Bundle a default LaunchScreen.storyboard file for an iOS app and make
sure it's referenced in the generated Info.plist file.
When launching Qt examples, it ensures the app uses the whole screen
space on the device rather than just a square-ish part of it.
The storyboard file is a copy of the qmake one, which qmake adds
to the Xcode projects it generates.
A custom launch screen can be provided either by setting the
QT_IOS_LAUNCH_SCREEN variable or by setting the
QT_IOS_LAUNCH_SCREEN target property.
The value must be an absolute path to the launch screen file.
The automatic addition of the launch screen entry in the Info.plist
file can be prevented by setting the QT_NO_SET_IOS_LAUNCH_SCREEN
variable to TRUE.
The automatic bundling of the launch screen file in the application
bundle can be prevented by setting the
QT_NO_ADD_IOS_LAUNCH_SCREEN_TO_BUNDLE variable to TRUE.
The current implementation has a limitation that only one launch
screen storyboard and one iOS executable can exist within a project.
If there are multiple executables in the project, all of them will
use the launch screen that is specified last (the last
qt_add_executable call).
Because of this limitation, the API is marked as Technical Preview,
to be improved upon in the future. For now it simply serves as an
improvement to the out-of-the-box experience of iOS apps built
with CMake.

When building Qt repos, all find_package(Qt6) calls request a

This means trying to configure qtsvg from a 6.3 branch using a

and no such Qt6 package version exists.
There are certain scenarios where it might be useful to try to do

One of them is doing Qt development while locally mixing branches.
Another is building a 6.4 QtWebEngine against a 6.2 Qt.

will still be accepted.
The warning will show both when building Qt or using Qt in a user

Certain platform-related variables, in this case UNIX, must be set in a

yet for INTEGRITY. This manifests in an undefined UNIX variable and

Add the CMake module "Platform/Integrity" in the cmake/platforms

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

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.

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()

We want to remove the Qt .pro files for projects, except examples,
because examples are still meant to build with qmake.
To not lose coverage on examples built with qmake, add instructions that
will build the qtrepo/examples folder with qmake when the CMake
configuration has -DQT_BUILD_EXAMPLES=ON.
This means that such configurations will build examples both with CMake
and qmake.
Aside from making sure that our examples will still build with qmake, it
will gives us some some coverage that a CMake-built qmake works
correctly.
Implementation-wise, add new instructions files that can call qmake and
make depending on configuration and target type.

...and include it in QtBuild.cmake.
Commit e8d8b1a5e4 added two different code paths to include
QtBuildInternalsAndroid.cmake.
This was needed, because:
In a top-level build, we must not include files that are not yet
installed. We have the source tree available, and
"${QT_SOURCE_TREE}/cmake" is in CMAKE_MODULE_PATH.
We can use the "module syntax" of the include() command.
In a per-repository build, when building against an installed qtbase, we
must not include files of the source tree, because that's not guaranteed
to be available. However, Qt6BuildInternalsConfig.cmake is installed,
and we can directly include QtBuildInternalsAndroid.cmake, which is
right next to it.
We can circumvent this whole issue by moving the Android-related
functions out of the Qt6BuildInternals package and including it in
QtBuild.cmake.

Add a new function that returns the minimum CMake version required to
build Qt. Pass that value to cmake_minimum_required() when building
qtbase and its standalone tests.
The minimum supported CMake version is read from qtbase/.cmake.conf
and its value should be updated when the need arises. It's the main
source of truth for all repos.
Provide a way to lower the minimum CMake version at configure time by
passing a value via QT_FORCE_MIN_CMAKE_VERSION.
This is not an officially supported way of building Qt. If the
specified version is lower than Qt's supported minimum, show a
warning.
Nevertheless the option is useful for testing how Qt builds with a
different minimum CMake version due to different policies being
enabled by default.
Issue warnings for CMake versions that are higher than the minimum
version but are known to cause issues when building Qt.
A counterpart change is needed in qt5 to ensure the minimum CMake
version is set at the proper time for top-level builds.
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.

For top-level builds it's desirable to have "ninja generate_docs" build
all tools needed to generate the documentation.
This is problematic since the doc-generating targets are created before
the doc tool targets. Thus, we must defer the dependency connection if
the doc tool target is not yet available.
This patch adds the functions qt_internal_defer_dependency and
qt_internal_add_deferred_dependencies.

It appears that CMake's Xcode generator default behavior can't really
handle imported object libraries location, which Qt uses extensively
(all the qt_add_resource calls).
Specifically the project fails to configure with the following error
message:
The OBJECT library type may not be used for IMPORTED libraries under
Xcode with multiple architectures.
An issue was filed upstream at
https://gitlab.kitware.com/cmake/cmake/-/issues/21276
In the mean time, it looks like it's possible to work around the issue
by setting XCODE_EMIT_EFFECTIVE_PLATFORM_NAME global property to OFF.
This needs to be done before the very first project() call, so we do
it in the generated Qt toolchain file.
Note that the workaround only works if the CMake project is configured
with a single architecture given to CMAKE_OSX_ARCHITECTURES.
If multiple arches are given, it will fail with the same error
message.

Add an abstraction over Qt::WinMain (aka qtmain.lib) and
iOS's runtime linker entry point (_qt_main_wrapper).
The Core target will now link against the Startup target on all
platforms, instead of just WinMain on Windows.
The creation and linkage interface definition of the Startup target
is done at find_package(Qt6Core) time via the private call of
_qt_internal_setup_startup_target().
This will add automatic linkage of WinMain to executables marked with
the WIN32_EXECUTABLE property on Windows.
As well as the addition of the '-Wl,-e,_qt_main_wrapper' linker flag
when linking iOS executables.
Qt users can opt out of this behavior by either setting the
QT_NO_LINK_QTMAIN property or variable. This is in line with
Qt 5 behavior.

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.
