It's perfectly possible to create static plugins in an otherwise shared
Qt build, but the logic to import these plugins into applications was
assuming a fully static Qt build. We now handle this more granularly.
This works for in-source tools and tests as well, which don't go through
the same CMake machinery for plugins as user projects do. The only case
that does not currently work is in-source examples, as they don't share
any of the plugin machinery with neither Qt internal tools/tests or user
project, but that's a bigger architectural issue that goes beyond this
change.

When recording which package version to look for in
QtFooModuleDependencies.cmake and other files like it,
instead of using PROJECT_VERSION, use the version of the
package that contains the dependency.
For example if we're hypothetically building the qtdeclarative repo
from the 6.4 branch, against an installed 6.2 qtbase, then
the Qt6QmlModuleDependencies.cmake file will have a
find_package(Qt6Core 6.2) call because qtdeclarative's
find_package(Qt6Core) call found a 6.2 Core when it was configured.
This allows switching the versioning scheme of specific Qt modules
that might not want to follow the general Qt versioning scheme.
The first candidate would be QtWebEngine which might want to
follow the Chromium versioning scheme, something like
Qt 6.94.0 where 94 is the Chromium major version.
Implementation notes.
We now record the package version of a target in a property
called _qt_package_version. We do it for qt modules, plugins,
3rd party libraries, tools and the Platform target.
When we try to look up which version to write into the
QtFooModuleDependencies.cmake file (or the equivalent Plugins and
Tools file), we try to find the version
from a few sources: the property mentioned above, then the
Qt6{target}_VERSION variable, and finally PROJECT_VERSION.
In the latter case, we issue a warning because technically that should
never have to happen, and it's a bug or an unforeseen case if it does.
A few more places also need adjustments:
- package versions to look for when configuring standalone
tests and generating standalone tests Config files
- handling of tools packages
- The main Qt6 package lookup in each Dependencies.cmake files
Note that there are some requirements and consequences in case a
module wants to use a different versioning scheme like 6.94.0.
Requirements.
- The root CMakeLists.txt file needs to call find_package with a
version different from the usual PROJECT_VERSION. Ideally it
should look for a few different Qt versions which are known to be
compatible, for example the last stable and LTS versions, or just
the lowest supported Qt version, e.g. 6.2.6 or whenever this change
would land in the 6.2 branch.
- If the repository has multiple modules, some of which need to
follow the Qt versioning scheme and some not,
project(VERSION x.y.z) calls need to be carefully placed in
subdirectory scopes with appropriate version numbers, so that
qt_internal_add_module / _tool / _plugin pick up the correct
version.
Consequences.
- The .so / .dylib names will contain the new version, e.g. .so.6.94
- Linux ELF symbols will contain the new versions
- syncqt private headers will now exist under a
include/QtFoo/6.94.0/QtFoo/private folder
- pri and prl files will also contain the new version numbers
- pkg-config .pc files contain the new version numbers
- It won't be possible to write
find_package(Qt6 6.94 COMPONENTS WebEngineWidgets) in user code.
One would have to write find_package(Qt6WebEngineWidgets 6.94)
otherwise CMake will try to look for Qt6Config 6.94 which won't
exist.
- Similarly, a
find_package(Qt6 6.4 COMPONENTS Widgets WebEngineWidgets) call
would always find any kind of WebEngine package that is higher than
6.4, which might be 6.94, 6.95, etc.
- In the future, if we fix Qt6Config to pass EXACT to its
subcomponent find_package calls,
a find_package(Qt6 6.5.0 EXACT COMPONENTS Widgets WebEngineWidgets)
would fail to find WebEngineWidgets, because its 6.94.0 version
will not be equal to 6.5.0. Currently we don't pass through EXACT,
so it's not an issue.

CMake has logic to rewrite build rpaths that contain
CMAKE_STAGING_PREFIX to instead point to CMAKE_INSTALL_PREFIX.
This breaks running executables from the build directory, because
their build rpath will point to a location where the libraries might
not exist yet (we didn't install Qt yet).
Work around this by setting CMAKE_STAGING_PREFIX to a fake path, so
that CMake does not do the rewriting anymore.
CMAKE_STAGING_PREFIX needs to be set at subdirectory scope, not
function scope, which is why
qt_internal_apply_staging_prefix_build_rpath_workaround() is a macro
that is called from within each Qt internal function that creates
a target.
The workaround can be disabled by configuring with
-DQT_NO_STAGING_PREFIX_BUILD_RPATH_WORKAROUND=ON
The downside of this workaround is that it breaks per-subdirectory
install rules like 'ninja src/gui/install'.
Regular global installation like 'ninja install' works fine.
This is similar to what we do for tests in
qt_set_up_fake_standalone_tests_install_prefix()
introduced by 20292250d4
The reason it's not as good for other target types is because in
contrast to tests, we do want to install them.
In case if someone does call `ninja src/gui/install' they will most
likely get a permission error, telling them it's not possible to
install into

Previously we only created object library static plugin initializers
for Qt plugins only, not user-project plugins.
The reason was that if a user tried to install the plugin target via
an export set, CMake would error out saying that the _init library is
not part of the same export set.
Introduce an OUTPUT_TARGETS option that would allow projects to get
the name of the generated _init target, so they can install it if
needed.
This was already done for qt6_add_qml_module, so we just introduce the
same option for qt6_add_plugin.
Now user static plugins will have an _init target created, which will
be propagated to consumers whenever the consumers link against the
plugin itself.
We also need an internal option to disable this propagation, because
it's handled a bit differently for Qt plugins which can be linked
either via finalizers or via usage requirements.

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.

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).

For each plugin, we create a custom target with it's OUTPUT_NAME such
that one simply can do 'ninja qtuiotouchplugin' to build it.
QTuiTouchPlugin has qtuiotouchplugin as OUTPUT_NAME, which is
problematic with Makefile generators on case-insensitive file systems.
See CMake upstream issue #21915 for details.
Work around this issue by not creating the custom target in this
situation.

Associated changes in the qtdeclarative repo now ensure that arguments
for qml plugins are handled on the calling side. This reduces the
qml-specific logic needed in qtbase and gives qtdeclarative clearer
control over qml build and install locations.
As part of that work, the INSTALL_LOCATION keyword used in
qt_internal_record_rcc_object_files() has been renamed to
INSTALL_DIRECTORY to make it consistent with the keyword used for the
same concept in other commands.

Contrary to its name, this command was also setting a target property.
Since it was only called in one place and that caller can just as
easily set the property instead, rename the command to make clear its
internal nature and refactor it so that the caller is responsible for
setting that property instead.
Also make it an error rather than just a warning if the command is used
for a target that doesn't belong to any module. Since this is now
unambiguously an internal command, we should always expect the target
to belong to a module.

The pro2cmake.py conversion script faithfully reproduced the .pro files
for the plugins, which specified the libraries as public. But in CMake,
the implications of this are that public usage requirements should then
be propagated to consumers. We don't expect any consumers, since a
plugin is created as a MODULE library in CMake, so for Windows we don't
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).

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.

The QT.<module>.DEFINES assignment in pri files needs to take into
account the module name when computing the define name. This is the
MODULE value that qmake specifies.
In CMake that would be the value of CONFIG_MODULE_NAME.
Previously the value of the define was computed in
qt_internal_module_info() without taking into account the module name.
While qt_internal_module_info() ended being used also for plugins and
other target types, the defines computed by it were meant to be used
only for Qt modules.
Thus remove the <result>_define assignment from
qt_internal_module_info and move its computation directly into
qt_internal_add_module, taking into account the value of
CONFIG_MODULE_NAME.
The only other use of module_define was in qt_internal_add_plugin but
that was merely a long overdue copy-paste error, qmake doesn't
propagate QT_FOO_LIB defines for plugins.
As result, a define special case in testlib is not needed anymore,
because the define is now computed properly.
Finally, QT_FOO_LIB should not be used while building the Qt module
itself, so instead of using PUBLIC_DEFINES option of
qt_internal_extend_target, use target_compile_definitions(INTERFACE)
directly.

WaylandClient -> qtwaylandscanner

- default_qpa_plugins accidentally depended on non-qpa plugins.
- All qpa plugins were enabled by default, including the wayland ones.
Fix the default_qpa_plugins target not to depend on regular non-qpa
plugins.
Also fix qpa plugins not to be enabled by default, but instead only
choose one qpa plugin to be the default (via evaluating the
DEFAULT_IF) condition.

Building a user project in Release configuration against a Qt built with
CMAKE_CONFIGURATION_TYPES=RelWithDebInfo;Debug led to the user project
being linked against the Debug Qt libraries. This is especially painful
with MSVC where debug and release runtimes are incompatible.
We now create *AdditionalTargetInfo.cmake files along the
exported *Targets.cmake files that set the IMPORT_*_<CONFIG> properties
to the values of the release config Qt was built with.
User projects built with an unknown
configuration (CMAKE_BUILD_TYPE=ArbitraryName) will link against a
release Qt. This can be controlled by setting the variable
QT_DEFAULT_IMPORT_CONFIGURATION to, for example, DEBUG in the user
project.
