fb9cbd3b2a CMake: Clean up and simplify qt6_extract_metatypes implementation
Remove copying of json files in non-prefix builds.
Previously, this was done to mimic the directory layout of prefix
builds in a non-prefix build, but the extra complexity is not worth
it.
Keeping the files in the build directories of each repo in a
non-prefix build should be good enough.

As a result, we don't need to distinguish which file path should be
passed in INTERFACE_SOURCES. Now we have only 2 paths to consider, the
BUILD_INTERFACE one and the INSTALL_PREFIX one, rather than 3
different paths.

Move the code that handles installation closer together.

Rename the internal COPY_OVER_INSTALL option to
___QT_INTERNAL_NO_INSTALL.
We might want to expose it as a public option later, but it depends on
whether we will disable default installation for user projects.

Remove assignment of some properties that are not used anymore.

e0a0101290 CMake: Apply bitcode flags to internal plugin object lib initializers
All internal libraries, plugins, object libraries (resources, plugin
initializers) need to be built with bitcode flags when targeting iOS.

Internal here means all libraries added by qt_internal_add_X
functions or associated with internal libraries.

We didn't do that for plugin initializers, which were added not too
long ago.

Extract the logic that links to Qt::PlatformModuleInternal into a
separate function to be used for object libraries.
Use it for resources and plugin initializers. It will also be used
in qtdeclarative for qml plugin initializers.

3595613a0a CMake: Don't propagate -fapplication-extension to user projects
Both the compiler and linker -fapplication-extension flag should only
be applied when building Qt's libraries (not executables).

It's up to the user project whether their code will be restricted with
application-extension-only APIs.

In qmake that can be achieved by adding to the qmake project
  CONFIG += app_extension_api_only

In CMake it can be achieved by either adding the compiler and link flags
in the project directly (using target_X_options) or by setting the
appropriate setting in the Xcode project when using the Xcode
generator.

And we don't link anything when building Qt for iOS itself, we only

The final decision whether bitcode should be used is up to the Xcode

Bitcode compile flags are still added when building Qt itself.

adfb767bcc Move the logic associated with platform definition directory
Since platform definition directory is used as an interface include
path of the Qt::Platform target, it makes sense to define it for this
target only. Also the definition of cached values that contain
path to platform definition looks redundand.

The definition of QT_PLATFORM_DEFINITION_DIR from command line
doesn't make any sense since build procedure doesn't take it into
account when installing mkspecs and the use if the user-provided
QT_PLATFORM_DEFINITION_DIR value as a Qt::Platform include directory
causes inconsistency in the prefixed builds. INSTALL_MKSPECSDIR
and QT_QMAKE_TARGET_MKSPEC should be used instead.

451733bd57 CMake: Fix reconfiguration error when features have EMIT_IF conditions
Previously, if a feature was marked as not to be emitted and there was
no user provided value for that feature, the build system would still
save the user provided value in FEATURE_foo with a value of ON (if the
conditions were met).

After a reconfiguration, the build system would hit the code path that
checks if the user provided a value for the non-emitted feature, and
would then warn about it and reset the feature value to OFF.

This would cause errors when reconfiguring a user project, complaining
that a feature value has changed.

Make sure to not save the user provided value for a non-emitted
feature and to always set its internal feature value to OFF.

51ae235080 CMake: Use correct MSVC runtime library for Qt object libraries

-MT flag, the plugin initializer object libraries were still compiled
with the default -MD flag.

When an application linked to Qt, that caused linking to fail with
mismatched symbol errors between the application symbols and the
plugin initializer object library symbols.

Make sure to set the MSVC_RUNTIME_LIBRARY property on both plugin
initializer and resource object libraries, depending on the value of
QT_FEATURE_static_runtime.

We did set the property for resources added by
qt_internal_add_resource, but not for the resource created by
the public qt6_add_resources counterpart.

Building a CMake project with CMAKE_BUILD_CONFIG=Debug was broken for
non-prefix debug-and-release builds of Qt.

In debug-and-release builds we set EXCLUDE_FROM_ALL on tools in the
Debug configuration. In non-prefix builds we export(EXPORT) targets, and
that also contains the non-existent Debug variants of the tools.  In
prefix builds, we install(EXPORT) instead, which only exports what is
built and installed.

Consequently, we now remove the DEBUG-related import information if the
debug variant if the target binary does not exist.

Our only way to detect whether the user requests an Android build of Qt

This approach is fragile and bound to break should the Android toolchain

is set. In that case, we do not peek into the toolchain file.

e80b010795 Use target_link_options to propagate object libraries
target_link_options are placed by CMake at the beginning of a linker
line. This gives us an opportunity to use the function to propagate
object libraries. This change adds one more check in the root
Config.cmake file. If CMP0099 policy is enabled, CMake enables
propagating of the linking options when linking two static libraries
using the PRIVATE linking visibility, so we can rely on the correct
linking order and expect object libraries to be propagated.

Note that on the platforms where cmake version is higher than 3.16
Qt uses CMP0099 NEW in functions like qt_add_executable. This means
that at the moment of creating an executable target the TARGET_POLICY
genex will also be NEW, so we do not take into the account the user
defined CMP0099.

If the CMP0099 policy is not available for a certain CMake version
we skip the TARGET_POLICY check and simply disable propagation of
the object libraries using target_link_options for both user and Qt
libraries. This is applicable for the CMake versions 3.16 and less.

Linking approaches have the following priorities(from higher to lower)
after this change:
  - target_link_libraries - works if link order matters not or CMake
    version greater equal 3.21.
  - target_link_options - works if CMP0099 is set to NEW by user or
    if the CMake version is greater than or equal to 3.17 and an
    executable is created using Qt functions.
  - object library finalizer - works if CMake version is greater equal
    3.19 or qt6_finalize_target is called explicitly.
  - target_sources - is used when all the other approaches could not
    be used.

bb25536a3d CMake: Fix Vulkan to be found when targeting Android
Introduce two new packages WrapVulkanHeaders and WrapVulkan similar to

WrapVulkanHeaders uses FindVulkan and is marked as found if Vulkan
headers are found (that's the only part the Qt build requires).

The WrapVulkan package is currently not used, but is there for
symmetry.

The Vulkan feature is now disabled by default on QNX, because the
QNX toolchain file in the CI does not set
CMAKE_FIND_ROOT_PATH_MODE-like variables and CMake ends up finding
host Vulkan headers causing the build to break.

82063d9af1 CMake: Pierce through LINK_ONLY deps in finalizer dep traversal
Ensure that the finalizer approach of
__qt_internal_propagate_object_library considers $<LINK_ONLY:>
libraries when traversing the dependencies of a target.

The issue was discovered when using the Quick.Shapes QML module in a
static build. The module has both a backing library and a plugin.
The backing library has some resource objects associated with it.
When the targets are exported, the plugin INTERFACE_LINK_LIBRARIES
has a $<LINK_ONLY:QuickShapes> dependency.

This ensures that the library will be linked, but depending on which
linking approach in __qt_internal_propagate_object_library is used,
the resources might not be linked to the final executable.

The resources are linked correctly when using the
target_link_libraries approach, but not when using the finalizer or
target_sources approach.

This change fixes the finalizer approach, but the target_sources
approach is still broken.

1981682687 CMake: Propagate sanitizer flags to public projects
Ensure that Qt user projects build with sanitizer flags if Qt was
configured with any of the sanitizers enabled.

To compile Qt with sanitizer support enable any of Qt sanitizer
features.

Passing -DECM_ENABLE_SANITIZERS=address to CMake is NOT supported
anymore.

When configuring Qt using CMake directly, pass
    -DFEATURE_sanitizer_address=ON
    -DFEATURE_sanitizer_undefined=ON
instead of
    -DECM_ENABLE_SANITIZERS=address;undefined

When configuring Qt with the configure script pass
    -sanitize address -sanitize undefined
as usual.

QtConfig.cmake now records the sanitizer options that should be
enabled for all consuming projects based on the enabled Qt features.
This applies to internal Qt builds as well as well as tests an
examples.

The recorded sanitizer options are assigned to the ECM_ENABLE_SANITIZERS
variable in the directory scope where find_package(Qt6) is called.
The ECMEnableSanitizers module is included to add the necessary flags to
all targets in that directory scope or its children.

This behavior can be opted out by setting the
QT_NO_ADD_SANITIZER_OPTIONS variable in projects that use Qt and might
be handling sanitizer options differently.

d6e01ae05c Fix QT_HOST_DATA for builds setting INSTALL_MKSPECSDIR
In a Qt build that was configured with INSTALL_MKSPECSDIR set to
something different than INSTALL_DATADIR, the qmake property
QT_HOST_DATA was wrong. Consequently, mkspecs could not be loaded,
rendering qmake dysfunctional.

The reason was that we considered every QT_HOST_xxx property to have the
same value as QT_INSTALL_xxx in a non-cross build.
This is not true for QT_HOST_DATA, because users might want to set
INSTALL_DATADIR to "foo" but INSTALL_MKSPECSDIR to "bar/mkspecs".

Move the unused determination of the host data dir to the QtLibraryInfo
lib and handle QT_HOST_DATA specially.

7ee4468a18 wasm: enable MODULARIZE option and set EXPORT_NAME
Make Emscripten generate a global constructor function
("createQtAppInstance()") instead of a global javascript
module object.

This enables more fine-grained control over module
instantiation; previously the module object would be
created when the runtime javascript was evaluated, and
the number of emscripten module/instances was limited
to one per page.

Set EXPORT_NAME to “createQtAppInstance” which avoids
collisions with other non-Qt Emscripten modules on
the same page. A further improvement would be to include
the app name in EXPORT_NAME, but this is not done at
this time.

Update the code in qtloader.js to call the constructor
function instead of working on a global module object.
The qtloader.js API is functional before the wasm and
Emscripten modules have been instantiated; store properties
and forward to the Emscripten module when it's created.

5fb99e3860 Check the impact of static link order for user projects
For user projects we run the static link order check once
'find_package(Qt6 ...)' is called.

If linker can resolve circular dependencies between static libraries
and object files we set the _qt_link_order_matters property of the
Qt::Platform target. This indicates the use of finalizers is not
required and we may rely on CMake-base propagation of resource
libraries and resource object files.

If linker could not resolve circular dependencies depending on
the _qt_resource_objects_finalizer_mode value:
  - Finalizer will be called and collected resource objects will be
    linked to the target directly.
  - Finalizer will be omitted and resource objects will be linked
    using the target_sources function implicitly. This only
    propagates resource one level up if consumer links the static
    library PUBLICly, but all symbols will be resolved correctly
    since object files are placed in the beginning of the linker line.

In the CMake version 3.21 we expect that CMake will take care about
the order of the resource object files in a linker line, it's
expected that all object files are located at the beginning of the
linker line.

TODO: Need to confirm that the CMake 3.21 meets the expectations.

561fc8107f CMake: Allow promoting the Qt libraries to be global targets
User projects can set the QT_PROMOTE_TO_GLOBAL_TARGETS variable to
true so that the various imported targets created by find_package(Qt6)
are promoted to global targets.

This would allow a project to find Qt packages in a subdirectory scope
while using those Qt targets from a different scope.

E.g. it fixes errors like

  CMake Error at CMakeLists.txt:5 (target_link_libraries):
  Error evaluating generator expression:

    $<TARGET_OBJECTS:Qt6::Widgets_resources_1>

  Objects of target "Qt6::Widgets_resources_1" referenced but no such
  target exists.

when trying to use a static Qt from a sibling scope.

Various 3rd party dependency targets (like Atomic or ZLIB) are not
made global due to limitations in CMake, but as long as those targets
are not mentioned directly, it shouldn't cause issues.

The targets are made global in the generated
QtFooAdditionalTargetInfo.cmake file.

To ensure that resource object libraries promoted, the generation
of the file has to be done at the end of the defining scope
where qt_internal_export_additional_targets_file is called,
which is achieved with a deferred finalizer.

Replaced all occurrences of target promotion with a helper function
which allows tracing of all promoted targets by specifying
--log-level=debug to CMake.

2c49f85380 CMake: Fix generated prl and pri files for MSVC
In MSVC static build, if we build Qt with 3rdparty library (e.g. zstd),
cmake will add"zstd" (without "-l" prefix) to Qt6Core.prl. Then we
use this Qt to build a qmake project, compilation will fail due to
missing zstd.obj. Without "-l" prefix, qmake will treat "zstd" as an
object file instead of a library.

Library names in qt_module.pri and qt_lib_*_private.pri are also
missing "-l" prefix.

This is because on most compilers, CMAKE_LINK_LIBRARY_FLAG equals
"-l". But on MSVC, it is an empty string. So we should pass
"-DLINK_LIBRARY_FLAG=-l" for MSVC.

Also add "-L/path/to/library" if the library path is not in default
linker search directories. This will write un-relocatable paths to prl
files only when using 3rdparty libraries to build Qt statically. Usually
it's not a problem.

In addition, CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES is also empty on
MSVC. So The third argument of "$<FILTER>" is empty, it is an invalid
generator expression. This means no include dir will be written to
qt_module.pri and qt_lib_*_private.pri on MSVC. So only use "$<FILTER>"
when CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES is not empty.

This removes the previous behavior of using the finalizer mode if
qt_import_plugins is called. Instead the old regular mode is used
if the above preconditions are not met.

The removed behavior had ordering issues if qt_import_plugins was called
before target_link_libraries. The dependency walking would be done
before Qt dependencies were added and thus no plugins would be
linked.

d97fd7af2b Build examples in isolated sub-builds using ExternalProject
Examples are intended to show how to build against an installed Qt.
Building them as part of the main build means the way the Qt targets
are defined and created are not representative of an end user's build.
By building them as separate projects using ExternalProject, we can
more closely replicate the intended audience's environment. This
should allow us to catch more problems earlier.

Having examples built as part of the main build also creates problems
with some static builds where a tool built by the main build is needed
during configure time. This happens with other repos like qtdeclarative
but not (currently) with qtbase. Converting the examples in qtbase to
be built using ExternalProject is intended as a demonstrator for how
other repos can do similar. Until other repos are converted, they will
continue to work as they did before, with examples as part of the main
build for non-static builds only.

The new build-externally behavior is only supported for non-prefix
builds with this change. Prefix builds will continue to use the old
non-external method. Support for building examples externally in
prefix builds will be a separate change.

_qt_internal_add_library forwards arguments to add_library with some

whether Qt is configured as static or shared).

The new _qt_internal_add_library is now used in qt_add_plugin as well
as some internal library creating functions like
qt_internal_add_module.

This reduces some duplication of file name adjustments across
functions and creates a central point for creation of Qt-like
libraries (for some definition of Qt-like).

f9c850cc42 qmake: Pick default architecture on macOS based on uname
When dealing with a universal build of Qt, we would end up
using the QT_ARCH as the architecture for user projects,
but this architecture is always the primary one that Qt
was configured with.

Instead of relying on QT_ARCH, we start writing QT_ARCHS
(plural) to qconfig.pri, based on CMAKE_OSX_ARCHITECTURES,
and then use that to initialize QMAKE_APPLE_DEVICE_ARCHS.

We then resolve the active arch using uname -m, matching
what CMake does.

We still feed all the available architectures to the
Makefile or Xcode project, so that the user can build
for any of the available architectures without needing
a reconfigure.

5b64e5950c Do not expose Qt internals by the HEADER_MODULEs
HEADER_MODULEs use the INTERFACE visibility to link libraries. This
causes a transitional propagating of the Qt-internal compile definitions
and options to the user targets.

This commit avoids an implicit adding of the Qt::PlatformModuleInternal
library to the HEADER_MODULEs and stops propagation of the Qt-internal

425ff34aa1 Merge main and private targets of the internal modules
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.

4b09522c23 Add support for building and installing repo target sets
Introduce the concept of repository target sets, which is a named set of
targets within a Qt module repository.

In a Qt repository, a repo target set 'qtfoo' can be defined in the
top-level project file with
    qt_internal_define_repo_target_set(qtfoo DEPENDS Bar Baz)

The DEPENDS argument specifies Qt components that need to be
find_package'd when building the targets that belong to qtfoo.

In subdirectory project files, use
qt_internal_include_in_repo_target_set(qtfoo) to mark the file as
belonging to the repo target set.

To build and install a single repo target set, specify
QT_BUILD_SINGLE_REPO_TARGET_SET=qtfoo when configuring the Qt
repository.

6fcc272ac9 CMake: Introduce finalizer mode handling of static plugins
Allow linking all plugin initializer object libraries directly
into the final target (executable or shared library).

The finalizer mode is triggered when the project adds a call
to qt_import_plugins, as well when the project has an explicit
call to qt_finalize_executable or when it is defer called by
CMake 3.19+.

Otherwise the old non-finalizer mode is used, where each plugin
initializer object library is propagated via the usage
requirements of its associated module.

A user can explicitly opt in or out of the new mode by calling
qt_enable_import_plugins_finalizer_mode(target TRUE/FALSE)

The implementation, at configure time, recursively collects all
dependencies of the target to extract a list of used Qt modules.

From each module we extract its list of associated plugins and
their genex conditions. These genexes are used to conditionally
link the plugins and the initializers.

Renamed QT_PLUGINS property to _qt_plugins, so we can safely query the
property even on INTERFACE libraries with lower CMake versions.
QT_PLUGINS is kept for backwards compatibility with projects already
using it, but should be removed in Qt 7.

The upside of the finalizer mode is that it avoids creating link
cycles (e.g. Gui -> SvgPlugin -> Gui case) which causes CMake to
duplicate the library on the link line, slowing down link time as well
as possibly breaking link order dependencies.

The downside is that finalizer mode can't cope with generator
expressions at the moment. So if a Qt module target is wrapped in a
generator expression, it's plugins will not be detected and thus
linked.

91c65dd80c CMake: Build plugin initializers as object libs
Instead of compiling the plugin initializers as part of a user
project, pre-compile them as object libraries while building Qt.

The installed object libraries can then be used with

    target_sources(qt_module INTERFACE $<TARGET_OBJECTS:plugin_init>)

so that they are linked into the final executable or shared library
via qt module usage requirement propagation.

This reduces the build times of user projects.

The link line placement of the object files should be correct for all
linux-y linkers because the only dependency for the object files is
Core and the Gui -> plugin -> Gui -> Core cycle does not hamper that
from empirical observations.

As a consequence of the recent change not to link plugin initialization
object files into static libraries, as well not having to compile the
files in user projects, we can get rid of the
_qt_internal_disable_static_default_plugins calls in various places.

A side note.

Consider a user static library (L) that links to a Qt static library
(Gui) which provides plugins (platform plugins).

If there is an executable (E) that links to (L), with no direct
dependency to any other Qt module and the intention is that the
executable will automatically get the platform plugin linked,
then (L) needs to link PUBLIC-ly to (Gui) so that the plugin usage
requirements are propagated successfully.

This is a limitation of using

  target_sources(qt_module INTERFACE $<TARGET_OBJECTS:plugin_init>)

which will propagate object files across static libraries only if
qt_module is linked publicly.

One could try to use

  target_link_libraries(qt_module
                        INTERFACE $<TARGET_OBJECTS:plugin_init>)

which preserves the linker arguments across static libs even if
qt_module is linked privately, but unfortunately CMake will lose
dependency information on Core, which means the object files might be
placed in the wrong place on the link line.
As far as I know this is a limitation of CMake that can't be worked
around at the moment.

Note this behavior was present before this change as well.

Q_IMPORT_PLUGIN generates a global static symbol that initializes a
plugin. If this symbol is added to a static library and the library
is then linked to an executable, the linker decides that the symbol is
unused (because nothing references it) and discards it.

This means there's no point to compile the Q_IMPORT_PLUGIN containing
files into static libraries.

associated modules to not compile and link the plugin initialization
object file into a static library.

Allow collecting all public dependency CMake targets starting from

Note that the private dependencies of a non-static target (like a
shared library or executable) are not walked by the new mode.

Introduce a new function called
__qt_internal_collect_all_target_dependencies which uses the new
mode to collect the full private dependency list of a target.

The final list only contains targets, so no linker flags or file
paths.

582fdf06d1 Make a documentation-only build possible
Packagers usually build Qt per repo, but the documentation must be built
from the full Qt source archive to ensure that inter-repo links are set
up correctly. When building the documentation, it's desirable to avoid
building tools and re-use to tools of an existing Qt build.

One now can do a documentation-only build by configuring Qt like this:

    cmake /path/to/Qt/source -GNinja \
          -DQT_HOST_PATH=/path/to/Qt/installation

and build the documentation with

    ninja docs

To avoid building tools, this patch removes the DEPENDS arguments from
some add_custom_target calls in QtDocsHelpers.cmake and makes another
one conditional. The removed dependencies are added at the end of
qt_internal_add_docs. Adding of tool dependencies is not done if
QT_HOST_PATH is set.

52077d4f01 Inhibit CMake generator detection for qt-configure-module
When configuring a Qt module with qt-configure-module, we want to use
the same CMake generator that was used for building qtbase.
That generator is encoded in qt-cmake-private. But qt-configure-module
overrides the generator after trying to detect what generator should be
used. That auto-detection is only useful for qtbase-builds and top-level
builds. Turn it off for repo builds other than qtbase.

31ee3c84a7 CMake: Install prl files from all repo build dirs in a top-level build
Previously, in a top-level build we always generated the final prl
file somewhere under QT_BUILD_DIR (which is qtbase_build_dir). After
each repo was processed by QtPostProcess.cmake, we installed the prl
files found in PROJECT_BINARY_DIR.

For qtquickcontrols2 this meant that qml plugin prl files were placed
under qtbase/qml, but we tried installing the prl files from
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
the qtbase/plugins/imageformats folder. We then process
qtimageformats plugins, see webp, issue another install rule from
under qtbase/plugins/imageformats.
The first install rule will install both qjpeg and qwebp, the second
install rule will merely say all plugins are up-to-date.

f1c37ead59 Error out if requesting Android build without toolchain file
Passing Android-related variables to the initial CMake call would have
no effect if no (or an empty) value of CMAKE_TOOLCHAIN_FILE was
specified. To alleviate user confusion, yield an error if an Android
build was apparantly requested, but the toolchain file is missing.
