aab8a0ac6e CMake: Warn when using CMake 3.20.1 due to crashes in AUTOMOC
With CMake 3.20.1 AUTOMOC can crash or hang on Windows when used with
a Qt installation that supports moc depfiles due to missing
multi-threaded locking.
Warn and advise to use a different CMake version instead.

6cefc83875 CMake: Don't consider /opt/homebrew as a system path for arm64 macOS
Homebrew introduced a new default prefix for Apple Silicon machines,
so that both arm64 and x86_64 packages can be co-installed on a single
system.
The intel packages are installed into /usr/local and the arm64
packages are installed into /opt/homebrew.

For Qt building purposes, we don't want to find packages in any of
homebrew's prefixes unless explicitly requested by the user

Currently our arm64 macOS CI config does pick up system libs under new
prefix.
Remove the new path from the system prefixes.

9cd7d83069 Check if all required Qt targets are declared when finalizing the module
CMake makes possible to specify a target in the target_link_library
call even if the target is not declared yet. This adds flexibility to
the target declaration arrangement. For the Qt modules we have to
restrict freedom, because of the .prl files generating. If the Qt
module depends on another Qt module, the dependecy must be declared
before the module finalizing step, otherwise this will cause invalid
records in the module .prl file.

TODO: The dependency order issue could be solved by using conditional
genex's when generating step1 .prl file. But we ask developers to
depend on Qt module targets that have been defined before their usage.

The find script checked for UIKIT which is set during a Qt build
in QtPlaformSupport.cmake but is not set when building a user project.
This casused the find script to skip the iOS specific code that

that pass -DCMAKE_SYSTEM_NAME=iOS.

e379147f95 CMake: Fix default architecture selection for macOS and iOS
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.

b6dd5d7c3b CMake: Fix auto-importing of plugins in static Qt qmake projects
Previously the plugin .pri files that CMake generated for qmake
consumption contained an '-' to exclude the plugin from
auto-importing only if the plugin type was generic or a platform
plugin.

Now that plugin projects that should be excluded have a proper
 DEFAULT_IF FALSE
clause, we can simply query for the defaultness of the plugin
to know whether to exclude it in the generated .pri file.

This fixes an issue with Qt static builds and qtvirtualkeyboard.

The vkb plugin was not excluded and thus any simple QtGui app
linked to the vkb plugin in a static qmake project. This led to linker
issues because the vkb plugin also depends on a vkb quick plugin which
is not listed as a dependency.

qt_internal_add_executable has some special logic to link static
plugins in order to avoid issues with link cycles on exported
Qt module targets. This logic does not take into account if a plugin

On windows this caused duplicate symbol linking issues in static super

the same symbols.

Make sure to only link to default static plugins.

This will skip linking to qdirect2d because it's not a default qpa

70464b355e Specify QT_TESTCASE_BUILDDIR for Qt::Test users implicitly
QT_TESTCASE_BUILDDIR was implicitly defined by Qt::Test target for
library users in Qt5. By default, this definition will point to
CMAKE_CURRENT_BINARY_DIR. This logic works similarly to qmake logic.

From user's perspective it might be useful to not rely on standard
search paths, but specify own. This can be done by setting the
QT_TESTCASE_BUILDDIR property for the user's target. CMake will
substute the value of the QT_TESTCASE_BUILDDIR property into the
QT_TESTCASE_BUILDDIR definition.

The implicit QT_TESTCASE_SOURCEDIR also seems to be useful. According
to the current logic, it points to CMAKE_CURRENT_SOURCE_DIR.

4ed9402d7a Fix linking order of the resource objects
The generated object resource library depends on the Qt::Core library
because uses the functions defined in qresource.cpp. Dummy linking of
the Qt::Core to an object library has an effect only when the object
library is linked directly to the executable as a target. If we link
the object library as INTERFACE library we miss out all the objects
that need to be linked to the executable. This behavior is explained
here:

    https://bit.ly/3sFWKvI

Thus, the only option to link the object library objects to the
endpoint executable is to use TARGET_OBJECTS property in genex, as
it's already done. But that means we are losing all profits that
target actually has, especially linking the object library dependencies.

The combination of both of the above methods does the job. The only
thing that looks fragile so far is order. Currently, the order we
use in the target_link_library call applies to the linker command line.
This means the object library objects must always appear before the
object library target.

659817e287 CMake: Fix building multi-arch universal macOS Qt
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.

That check didn't account for a qualified qt module target name.

This failed configuration of qtsvg which checked for the existence of
a namespace-less 'Gui' in a per-repo build.

Make sure to prepend the Qt namespace to the qt module name and also
handle aliased target names.

As a drive-by, add a TODO item to figure out how to link executables
to plugins who's plugin type belong to a different repo, but both the
executable and plugin are built in the current repo.

aa4a1006cb Refactor qt_internal_add_plugin() and qt6_add_plugin()
Remove code duplication by calling qt6_add_plugin() from
qt_internal_add_plugin().

Separate out the public and internal arguments for the
variables defined in QtBuild.cmake for these functions.
Provide them via commands instead for greater robustness.
This separation allows other Qt repos to access the appropriate
set of keywords where they define commands that forward
on to *_add_plugin() in their implementations. Retain
the old variables for now to simplify the integration
steps for updating other repos. The old variables can
be removed once there are no more references left to
them in any repo.

98e8180e56 Fix error when re-configuring an already installed Qt repository
When building and installing a Qt repo that provides plugins for a Qt
module within a different repository (for example, qtimageformats
providing imageformat plugins for QtGui), re-configuring that repository
would result in configuration errors like

"add_library cannot create ALIAS target "Qt6::QTgaPlugin" because
another target with the same name already exists."

This happened, because the find_package(Qt6 COMPONENTS Gui) calls pulled
in the Qt6*PluginConfig.cmake files that create imported targets for the
plugins we want to build.

To fix this, when building Qt, we now load only plugins that are
provided by repositories the currently building repository depends on.

We read the repo dependencies from dependencies.yaml when the
Qt6BuildInternals package is loaded, but only in static builds and only
if we're currently building a Qt repository.

To find out whether we're building a Qt repository, we check whether
QT_REPO_MODULE_VERSION is defined. We cannot check QT_BUILDING_QT,
because that variable is not available for the first find_package calls
in the repository's top-level project file.

In each Qt6*PluginConfig.cmake file, we bail out if the plugin's
repository is not one of the ones in QT_REPO_DEPENDENCIES.

9f444ce533 Add a way to install versioned hard-links for tools
Add the option argument INSTALL_VERSIONED_LINK to qt_internal_add_tool
and qt_internal_add_app. For tools/apps with this argument we create an
install rule that creates a versioned hard link. For example, for
bin/qmake we create bin/qmake6.

Note that this only applies to prefix builds.

Apply this argument to qmake.
The qt_internal_add_app change is necessary for qtdiag and in qttools.

59c3be7117 CMake: Fix qconfig.cpp embedded prefix in the CI
In the CI on a windows we configure Qt with the following prefix
-DCMAKE_INSTALL_PREFIX:PATH=\Users\qt\work\install

Note the lack of the drive letter.
This is intentional, so that we can abuse CMake's DESTDIR installation
mechanism to install into a custom path.

This causes trouble for static Qt builds in the CI.

Specifically when there is no qt.conf file next to qmake, qmake -query
will report a
  QT_INSTALL_PREFIX:/Users/qt/work/install
and ultimately qmake will fail to locate the module .pri files in such
a path, showing errors like:
  Project ERROR: Unknown module(s) in QT: core gui?

If a qt.conf is placed next to qmake (even an empty one), a differenct
code path is used in qmake to resolve the prefix, which returns a path
with a drive letter.

In a shared build, because the 'relocatable' feature is enabled by
default, a different code path is used and thus the prefix is
also successfully resolved.

So the problem is specific to static Windows Qt builds that have no
qt.conf file next to qmake.

This is the exact scenario that we encounter when running static
Qt tests (tst_qmake in particular).

To circumvent the issue, prepend a drive letter to the prefix
hardcoded into qconfig.cpp. Do that with
get_filename_component(REALPATH) which apparently resolves
to a fully qualified path.

5807e1ae81 Add plugins to Qt tools and executables for static builds
In static builds, we cannot allow any part of the main build to make a
call to find_package(Qt6...) where such a call may load a
Qt6*Plugins.cmake file. That would add additional dependencies to the
main module targets, setting up a circular dependency in the set of
*Config.cmake files which cannot be resolved. This scenario would be
triggered by per-repo builds or user projects.

But Qt's tools and other executables still need to load some plugins
in static builds. Sometimes a platform plugin may be enough, other
times we may want all supportable plugins (e.g. Qt Designer).
Therefore, add all plugins we can identify as relevant for an
executable that is part of the Qt build, but add them directly to the
executable without affecting the linking relationships between the
main module libraries.

Also remove the now unnecessary check for QT_BUILD_PROJECT_NAME in
top level builds because there should be no difference between per-repo
and top level builds any more (as far as linking static plugins is
concerned).

Examples that build as part of the main build will still build
successfully after this change, but they will not run if they require
a platform plugin. Examples need to be moved out to a separate build
where they can call find_package(Qt6) without QT_NO_CREATE_TARGETS
set to TRUE to be runnable (see QTBUG-90820).

even if the compiler is not icc or qcc.
Icc has the compiler id Intel according to

The compiler id for qcc is QCC according to

Qt requires CMake to be above 3.0.

d962c9ff85 CMake: Make Platform a dependency for all Qt internal targets
In particular that influences BundledLibrary targets.

Most internal targets already depended transitively on Qt::Platform
via Qt::Core as a public dependency. This was not the case for
BundledLibrary targets which don't link to Qt::Core.

This led to compilation issues in user projects when targeting
WebAssembly, due to mismatched flags between a bundled Harfbuzz vs
a user project. Probably other subtle issues as well (e.g. none of the
Windows specific compile definitions were passed to bundled libs).

Bundled libraries depend on PlatformCommonInternal already, so make
PlatformCommonInternal turn depend on the public Platform target.
I thought that was already the case, but we merely relied on the
Qt::Core dependency.

Note that Qt::Core should still list Platform as a public dependency,
so it gets propagated to user projects.

63a0d263cf Prevent static plugin triggering autogen dependency on reconfigure
A call to file(WRITE) will unconditionally update the file's timestamp
even if the file's contents don't change. The *Plugin.cpp file was
being written using configure_file() which avoids that, but the .cpp.in
file it was configuring from was being written out using file(WRITE)
every time CMake ran. Autogen saw that file as a dependency and then
regenerated the mocs_compilation.cpp file, which in turn results in
unnecessary rebuilds and relinking when nothing is actually changing.

The file(WRITE) - configure_file() dance is no longer needed anyway,
since the generated *Plugin.cpp file is very simple with no
substitutions required. Therefore, we can simplify that file's
generation with a single file(WRITE) that only executes if the file
contents will change or the file is missing.
