When configuring a static Qt with the -qt-zlib option and the build
system creates a 3rd party header module QtZlib, syncqt
does not generate a QtZlib header file that would include all its
public headers.
Then when the QtSvgDepends header is generated, it would add an
#include <QtZlib> which would break compilation of the QtSvg PCH
file (which compiles QtSvgDepends).
We have logic to exclude addition of headers from regular 3rd party
static libraries, but not header only 3rd party libraries.
Adjust the code to handle header-only 3rd party libraries, as well as
make sure it works across repos by exporting the relevant properties.
As a drive-by, also rename and export some other informational
properties.

Each included qml Qt6FooPluginTargets.cmake file checks whether
all the dependency targets that are referenced in the file already
exist by the time the file is included.
If one of the referenced targets is missing, the file sets
${CMAKE_FIND_PACKAGE_NAME}_NOT_FOUND_MESSAGE with a message mentioning
which targets are missing and also sets
${CMAKE_FIND_PACKAGE_NAME}_FOUND to FALSE.
All our qml package Config.cmake and Targets.cmake files are
include()d by Qt6QmlPlugins.cmake using a file(GLOB) which means the
order in which the files are loaded is implementation-defined.
Furthermore we didn't check the above set variables after each
inclusion, which means the values are overridden and the last plugin
to be loaded determines whether the Qml package is found or not.
If the last included file sets no error, it effectively silences any
previously set error.
Ever since we added dependencies between the qml plugin targets
themselves, we hit the above situation and depending on the platform,
no error was shown because the last file overrode any errors.
But we finally got a specific platform (wasm) which unearthed the
problem (QTBUG-97478). This can happen for any static Qt build though.
To fix this properly, we will most likely have to rewrite the whole
inclusion mechanism to use find_package() so that dependencies
can be resolved recursively as needed. This is a non-trivial change
that will have to be addressed in both qtbase and qtdeclarative.
In the mean time, a stop-gap solution that this change implements is
to include all the files while ignoring any error messages.
Then include the files one more time and check for error message after
each included file.
All qml plugin targets should have been brought into scope with the
first round of inclusions, thus circumventing "missing referenced
target" errors, while still catching any other possible errors.

The QT_ADDITIONAL_PACKAGES_PREFIX_PATH variable was introduced to
allow specifying extra locations to find Qt packages.
The reason it was introduced instead of just using CMAKE_PREFIX_PATH
is because the Qt6 component find_package call uses NO_DEFAULT_PATH
which means CMAKE_PREFIX_PATH is ignored.
We use NO_DEFAULT_PATH to ensure we don't accidentally pick up
system / distro Qt packages.
The paths from QT_ADDITIONAL_PACKAGES_PREFIX_PATH are added to the
find_package PATHS option in the Qt6 package, each
ModuleDependencies.cmake file and some other places.
Unfortunately that's not enough to make it work for cross-builds.
Imagine the following scenario.
host qtbase, qtdeclarative installed in /host_qt
target qtbase installed in /target_qtbase
target qtdeclarative installed in /target_qtdeclarative
We want to cross-build qtlottie.
We configure qtlottie as follows
/target_qtbase/bin/qt-configure-module /qtlottie_src -- -DQT_ADDITIONAL_PACKAGES_PREFIX_PATH=/target_qtdeclarative
We expect the target QtQuick package to be found, but it won't be.
The reason is that QT_ADDITIONAL_PACKAGES_PREFIX_PATH is added to the
PATHs option, but we don't adjust CMAKE_FIND_ROOT_PATH.
Without adding the new paths in CMAKE_FIND_ROOT_PATH, CMake will
re-root the passed PATHs under the existing CMAKE_FIND_ROOT_PATH,
which is QT_TOOLCHAIN_RELOCATABLE_INSTALL_PREFIX, which evaluates to
/target_qtbase. There is no QtQuick package there.
To fix this, prepend the values of QT_ADDITIONAL_PACKAGES_PREFIX_PATH
to CMAKE_FIND_ROOT_PATH.
The location where we currently do CMAKE_FIND_ROOT_PATH manipulations
is in the qt.toolchain.cmake file, so to be consistent, we prepend the
new prefixes there as well.
We need to adjust both CMAKE_FIND_ROOT_PATH and CMAKE_PREFIX_PATH,
due the path re-rooting bug in CMake.
See https://gitlab.kitware.com/cmake/cmake/-/issues/21937 as well as
the existing comment in qt.toolchain.cmake marked with
REROOT_PATH_ISSUE_MARKER.
We also need to do a few more things to make the setup work
Because Qt6Config uses NO_DEFAULT_PATH, the CMAKE_PREFIX_PATH
adjustments we do in the toolchain file are not enough, so we still need
to add the same prefixes to the Qt6Config find_package PATHS option.
One would ask why do we need to adjust CMAKE_PREFIX_PATH at all then.
It's for find_package(Qt6Foo) calls to work which don't go through
the Qt6Config umbrella package.
To make the CMake re-rooting behavior happy, we need to ensure the
provided paths are absolute.
So we iterate over the values of QT_ADDITIONAL_PACKAGES_PREFIX_PATH,
to make them absolute. We do the same for the environment variable.
We need to append lib/cmake to the prefixes which are added to
CMAKE_PREFIX_PATH, otherwise the CMake re-rooting bug is hit.
We need to specify the Qt6 package location (${_qt_cmake_dir}) to the
PATHS option in the various Dependencies.cmake.in files, to ensure
that dependency resolution can jump around between the Qt6 dir and
the additional prefixes. Previously the dependency lookup code assumed
that all dependencies would be within the same prefix.
The same is needed for qt and qml plugin dependency lookup.

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.

If a user project uses a Qt built with Vulkan support, but their system

The project will get compilation errors if it uses Vulkan headers, but

This use case was broken when fixing Vulkan to be found when building
Qt for Android.
Fix the regression with a combination of things
1) Mark the WrapVulkanHeaders package as optional (already the case)
2) Use the include directories directly when compiling Gui and OpenGL
3) Propagate WrapVulkanHeaders::WrapVulkanHeaders link requirement to
consumers only if the target exists. It won't exist if Vulkan
include dirs are not found
This also requires some changes in pri and prl file generation.
For prl file generation, we don't want to link to the
WrapVulkanHeaders target, so we filter out all dependencies that
use TARGET_NAME_IF_EXISTS for anything that calls
__qt_internal_walk_libs which includes qt_collect_libs.
For pri files, we make sure to generate a uses=vulkan/nolink clause
by inspecting a new _qt_is_nolink_target property on the target.
We also don't add include dirs to the pri file if the new
_qt_skip_include_dir_for_pri property is set.
This is intended for Vulkan, because there is separate qmake logic to
try and find the include dirs when configuring a user project.

In cmake, targets are used as an entity for modules. This causes a
number of problems when we want to manipulate a module as a separate
entity with properties associated with it.
The _qt_internal_module_interface_name target property is introduced to
represent the module entity. All modules write a name to this property,
which will subsequently expand into the module name matched with
the module name in qmake.
The 'qt_internal_module_info' function is responsible for providing the
correct values for the module properties used when working with a module
target.
Unlike qmake, for internal modules in cmake it is expected that the
Private suffix will be specified explicitly. In case the user wants to
have a different module name, an additional argument
MODULE_INTERFACE_NAME of the qt_internal_add_module function is
introduced.
This also changes the way how target dependencies are collected and
resolved. Since the 'Private' suffix no longer means an unique
identifier of the module 'Private' part, we look for the both Private
and non-Private package names when resolving dependencies.
TODO: This change doesn't affect the existing internal modules, so to
keep compatibility with the existing code the existing internal modules
create 'Private' aliases. The code that provides backward compatibility
must be removed once all internal modules will get the proper names.

For qtquickcontrols2 this meant that qml plugin prl files were placed

qtquickcontrols2/qml, which didn't have any prl files.
In a static Qt build, qmake's qt.prf calls qmlimportscanner to
identify which plugins should be linked to the executable. This worked
fine because the plugin .pri files were installed correctly.
None of the qml plugin library dependencies were linked in though.
This is supposed to happen in qmake's C++ code where it tries to
find the associated prl file of a linked library in order to extract
all its dependencies. Because no prl file was found, linking failed
with multiple undefined symbols.
Fix this by installing the prl files from QT_BUILD_DIR rather than
PROJECT_BINARY_DIR.
Note that this will create multiple install rules for certain files,
but it's harmless. An example is imageformats.
We process qtbase plugins, see qjpeg, issue an install rule from under

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

We read the repo dependencies from dependencies.yaml when the

To find out whether we're building a Qt repository, we check whether

When packaging different Qt versions for Linux distributions (or any
distribution with a common bin dir), Qt tools cannot be installed to
/usr/bin, because the executable names of the different Qt versions
clash.
To solve this conflict, our recommendation is to install Qt's tools to
/usr/lib/qt6/bin and to create versioned symlinks to user-facing tools
in /usr/bin.
User-facing tools are tools that are supposed to be started manually by
the user. They are marked in Qt's build system. Distro package
maintainers can now configure with
-DCMAKE_INSTALL_PREFIX=/usr
-DINSTALL_BINDIR=/usr/lib/qt6/bin
-DINSTALL_PUBLICBINDIR=/usr/bin
and will find a file called user_facing_tool_links.txt in the build
directory after the cmake run. Nothing will be installed to
INSTALL_PUBLICBINDIR.
Each line of user_facing_tool_links.txt consists of the installation
path of a user-facing application followed by a space and the versioned
link name in INSTALL_PUBLICBINDIR.
Example content:
/usr/lib/qt6/bin/qmake /usr/bin/qmake6
To actually create the versioned symlinks, the content of this file can
be fed to ln like this:
xargs ln -s < build-dir/user_facing_tool_links.txt
Or the package maintainer may decide to do something completely
different as suits their needs.
This patch adds the USER_FACING argument to qt_internal_add_tool to mark
tools as user-facing. In addition, every Qt created by
qt_internal_add_app is treated as user-facing.
The only tool this patch marks as user-facing in qtbase is qmake.

When doing a per-repository build of Qt, as it is done for the installer
packages, the build of qtbase has no knowledge of plugins that might be
built and installed from other repositories. That means we must not
write a fixed list of known plugins when exporting Qt modules of qtbase.
In particular, qtsvg adds imageformat plugins that are supposed to be
picked up by qtbase's QtGui module when linking a project against a
statically linked Qt.
${install-prefix}/lib/cmake/Qt6Gui/Qt6GuiPlugins.cmake missed the
include statements for qtsvg's plugin config files and operated on a
fixed list of plugins, all from qtbase.
Apart from that, the Qt6::Gui target's property QT_PLUGINS did only
contain the qtbase plugins.
This patch fixes the situation in the following way:
1. All Qt6*PluginConfig.cmake files in
${install-prefix}/lib/cmake/Qt6Gui are detected and included.
2. From those file names, the target names of the plugins are
deduced. This is safe as the file name of those generated files is a
direct result of the plugin's target name.
3. The QT_PLUGINS property of the module is updated with the detected
plugin target names.

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.

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.

Consider a Qt module with a 3rdparty library target in
PRIVATE_MODULE_INTERFACE, e.g. XKB::XKB in Qt6::GuiPrivate. Consumers of
GuiPrivate automatically depend on XKB::XKB. In order to do that they
must find_package(XKB ...). As all find_package calls for GuiPrivate are
in the same place as the ones for Gui, this package must be marked as
optional. Otherwise all consumers of Qt6::Gui would have to have the
xkbcommon package installed too.
This patch exports find_package calls for every 3rdparty public
dependency of private modules and marks them as optional.

Every public dependency of a Qt module results in a find_package call in

For example, vulkan is only needed if the user project actually uses Qt
classes that pull in vulkan headers.
This patch adds the option MARK_OPTIONAL to qt_find_package.
Dependencies that are marked as optional will not produce an error on
find failure.
