Since platform definition directory is used as an interface include

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

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

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.

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

This is needed for a change in qtdeclarative to allow building the
Q_IMPORT_PLUGIN-containing object library initializer of a qml plugin.
Show an error if the qml plugin has no class name, it's needed for
plugin initialization so it's mandatory to have a class name.
Show an error if a class name is not found when computing the import
macro for a plugin (both for a regular qt plugin and a qml plugin).
When querying for the class name of a target, query both a Qt6::
prefixed target as well as a non-prefixed one, with the Qt one
taking precedence.
This is to allow querying the class name of user project created qml
plugins.
Currently regular qt user plugins don't use the object library
initializer approach. This will likely be revisited in the future.

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

This would allow a project to find Qt packages in a subdirectory scope

E.g. it fixes errors like

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

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

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.

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
