Provide them via commands instead for greater robustness.
This separation allows other Qt repos to access the appropriate

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.

(cherry picked from commit c19d957f45fa27f61b5ecc566f8dbc19f12a44c3)
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.

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).

Most internal targets already depended transitively on Qt::Platform

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

Note that Qt::Core should still list Platform as a public dependency,

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.

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.

In static per-repo builds, we have a mix of targets provided by
packages and targets provided by the main build. For the builds that
create the packages, we must avoid adding a dependency for the main
module library target on its associated plugin targets or else the
package config files end up with a cyclic dependency that cannot be
resolved when something tries to consume them. This only happens for
static builds because we have been attaching a linking relationship
to the main module library that isn't really a true dependency, we
attached it only for convenience of things linking to that module
library.
To preserve that convenience linking without breaking the config
packages, we use the QT_NO_CREATE_TARGETS condition to prevent CMake
seeing that relationship when generating the *Config.cmake files.
Creating these relationships will be delayed until the plugin's
*Config.cmake file is loaded, at which point it will add itself to
the main module library's imported target INTERFACE (this was already
done before, we just now rely solely on that).

even have an import library to link with. The only exception to this is
for static builds where plugins are created as STATIC libraries
instead, but only in certain controlled situations do we then link to
plugins. Even then, usage requirements are not expected to propagate to
the consumers, so these relationships should always be specified as
private.
This change warns on any PUBLIC usage requirements specified for a
plugin. This check is disabled by default to avoid spamming CI builds
for repos that haven't been fixed yet. The check can be enabled by a
CMake cache option, which is intended for developers to use locally
when fixing this issue in other repos (all plugins in qtbase should
not trigger this warning as a result of changes in this commit).
