8b09c9d690 CMake: Fix config tests not finding module-provided CMake packages
This amends commit 165e01d5d5.

Above commit broke the code that adds "${PROJECT_SOURCE_DIR}/cmake" to
CMAKE_MODULE_PATH.  The semicolon that separates entries of
CMAKE_MODULE_PATH must be escaped.  Otherwise, the semicolon separates
elements of the flags list.

Additionally, fix the QT_AVOID_CUSTOM_PLATFORM_MODULES code path which
lacked the addition of "${PROJECT_SOURCE_DIR}/cmake".

326b91ea78 Fix missing QT.<module>.run_depends entries in module .pri files
The .pri files for public Qt modules were missing run_depends entries.
Those entries are used by qmake when linking plugins of a static Qt
build.  In shared builds, run_depends entries are used to decide whether
to add the -rpath-link argument to the linker.  In that matter,
run_depends entries serve a similar purpose as CMake's
IMPORTED_LINK_DEPENDENT_LIBRARIES.

In Qt5, run_depends entries consist of the qmake values QT_PRIVATE and
QT_FOR_PRIVATE.

QT_PRIVATE contains the Qt modules that are privately linked to the
public module, and QT_FOR_PRIVATE are the dependencies of the private
module.  That loosely translates to LINK_LIBRARIES of the public module
and INTERFACE_LINK_LIBRARIES of the private module.

Private modules whose public counterparts are already public
dependencies don't have to be added to run_depends.

f19668ce65 Don't use libs in /usr/local for configure tests by default on macOS
Since commit f3c7d22dd0 we do not use
libraries from /usr/local and other non-system locations on macOS.  But
our configure tests still did.  This led to discrepancies between
find_package calls in configure tests and the Qt project itself.

Mentioned commit removed /usr/local and friends from
CMAKE_SYSTEM_PREFIX_PATH.  But we can't pass this variable to the
configure tests, because CMake sets it up and overwrites our value.

Pass CMAKE_SYSTEM_PREFIX_PATH and CMAKE_SYSTEM_FRAMEWORK_PATH as
QT_CONFIGURE_TEST_CMAKE_SYSTEM_{PREFIX|FRAMEWORK}_PATH variables to
tests.

Tests with separate project files that call find_package() must add code
like this after the project() command:

if(DEFINED QT_CONFIGURE_TEST_CMAKE_SYSTEM_PREFIX_PATH)
    set(CMAKE_SYSTEM_PREFIX_PATH
        "${QT_CONFIGURE_TEST_CMAKE_SYSTEM_PREFIX_PATH}")
endif()
if(DEFINED QT_CONFIGURE_TEST_CMAKE_SYSTEM_FRAMEWORK_PATH)
    set(CMAKE_SYSTEM_FRAMEWORK_PATH
        "${QT_CONFIGURE_TEST_CMAKE_SYSTEM_FRAMEWORK_PATH}")
endif()

Adjust pro2cmake accordingly.

165e01d5d5 CMake: Ensure that UNIX is set for INTEGRITY
Certain platform-related variables, in this case UNIX, must be set in a
platform module, because they get cleared after the toolchain file is
loaded.  Such platform modules live in upstream CMake, but there is none
yet for INTEGRITY.  This manifests in an undefined UNIX variable and
"System is unknown to CMake" warnings for the project and every
configure test.

Add the CMake module "Platform/Integrity" in the cmake/platforms
directory.  Add this directory to CMAKE_MODULE_PATH to let CMake load
Platform/Integrity when the toolchain file set CMAKE_SYSTEM_NAME to
"Integrity".

CMake's module directory takes precedence, when loading platform
modules.  This is special for platform modules and different from the
documented behavior of CMAKE_MODULE_PATH and include().

In case the user wants to provide their own platform modules via
CMAKE_MODULE_PATH, they can instruct Qt to not add its path by setting
QT_AVOID_CUSTOM_PLATFORM_MODULES to ON.

Make sure that configure tests with project files also load the custom
platform module.

99899dd299 Revert "CMake: Warn if cmake_minimum_required has an unsupported low version"
This reverts commit 657525965b.

The change relied on reading the last value of the
CMAKE_MINIMUM_REQUIRED_VERSION variable before one of the Qt packages
is found to use it for the version check.

Even if a user project has a cmake_minimum_required() right at
the beginning of the project with a supported version specified,
the first project() call which loads a CMake toolchain file could
contain another cmake_minimum_required() call with a lower
(unsupported) version and that version would be used for the check,
failing the project configuration.

The Android NDK ships such a toolchain file, which requires version
'3.6'.

Thus, relying on the last value of CMAKE_MINIMUM_REQUIRED_VERSION is
not robust enough.

657525965b CMake: Warn if cmake_minimum_required has an unsupported low version
Qt6Config.cmake calls cmake_minimum_required to ensure a recent enough
CMake version is used in projects.

That call does not set policies in the calling subdirectory scope,
because find_package introduces a new policy scope.

If a project using Qt has a 'cmake_minimum_required(VERSION 3.1)'
call and is configured with a recent CMake, many policies will
still be set to OLD.

One such policy is CMP0071 (Run AUTOMOC on GENERATED files). The
policy value is queried at generation time rather than at target
definition time, which means we can't influence the policy value
(e.g. inside the implementation of qt_add_executable for example)

The inability to influence the policy value for targets created by our
own CMake functions is unfortunate and can lead to issues (in the case
of the above policy to compilation / linker issues).

Record the version of the last cmake_minimum_required call before
the Qt packages are found and error out if the version is lower than
the minimum supported one.

A project can reduce the error into a warning by specifying a
-DQT_FORCE_MIN_CMAKE_VERSION_FOR_USING_QT_IN_CMAKE_MIN_REQUIRED=3.xyz
option when configuring the project.
If the option is used and build issues arise, no official support is
given.

All the CMake example projects shipped with Qt specify a minimum
version of 3.16 already (which is the minimum for shared Qt builds),
so it shouldn't be an issue to require that in other user projects as
well.

Implementation wise, we follow the existing pattern to record
what the minimum and computed versions for static and shared Qt
builds are at qtbase configure time.
These are then checked before the Qt6 or QtFoo packages are
find_package'd.

725b52141d CMake: Introduce QT_BUILD_ONLINE_DOCS flag for documentation builds
QDoc modifies its linking behavior depending on whether the -installdir
command line option was set or not; Without -installdir, QDoc will
use 'https://<url>' to link to targets loaded from external
documentation modules, instead of using relative paths.

Drop the -installdir if QT_BUILD_ONLINE_DOCS was set. This behavior matches
the 'build_online_docs' scope that was used for qmake documentation
targets, and is useful for documentation projects that are not part of
Qt but want to link to Qt docs simply by loading the index files of Qt's
modules.

5d840f0f7a CMake: Get toolchain file path from EMSDK env for Wasm user projects
Try to to chainload the emscripten CMake toolchain file from the
EMSDK env var if it is set, instead of requiring the user to explicitly
specify a path to the file via QT_CHAINLOAD_TOOLCHAIN_FILE.

The order in which the toolchain file is chainloaded becomes is as
follows:

1) The initial toolchain file path that was specified when configuring
   qtbase is set written as the initial value of
   __qt_chainload_toolchain_file in qt.toolchain.cmake
2) If EMSDK env var is set, it overrides the value from 1)
3) If QT_CHAINLOAD_TOOLCHAIN_FILE cache var is supplied it overrides
   the value from 2)

Whichever value ends up in __qt_chainload_toolchain_file is
checked too see if the file exists.
If it exists it gets included, if it doesn't, a warning is issued.

This checking logic is a bit crude and should be improved and unified
with the Android chainload checking, but the current change already
improves the behavior for users of Qt.

configuration. An example of that is qtscxml.

When building standalone tests, qt_build_tests includes a repo
specific TestsConfig.cmake file to call find_package on the modules
that were built as part of that repo.

That doesn't quite work with a repo-target-set build which is enabled
when the repo is built with a QT_BUILD_SINGLE_REPO_TARGET_SET value.

The TestsConfig.cmake file would be overridden with different contents
on each configuration.

Fix that by including the QT_BUILD_SINGLE_REPO_TARGET_SET value as
part of the TestsConfig.cmake file to be generated and included.

This means that when configuring the standalone tests, the same
QT_BUILD_SINGLE_REPO_TARGET_SET value should be passed, so that the
correct packages are found.

Add some debug statements to allow checking which TestsConfig.cmake
file is loaded when the standalone tests are configured with
--log-level=DEBUG.

c8dbb177f0 CMake: Allow opting out of building examples as ExternalProjects
We default to configuring examples as separate ExternalProjects when
using a developer / non-prefix Qt build.

This ensures we test that the examples configure successfully without
the pollution of the main Qt build (e.g. already found packages).

One down-side of this is that a developer's IDE doesn't see these
example targets, unless each project is loaded into the IDE
separately. This is cumbersome to do when refactoring or renaming
code across multiple example projects.

Allow configuring the example projects as part of the main Qt build
by setting QT_BUILD_EXAMPLES_AS_EXTERNAL to FALSE when configuring Qt.

Save the value of the variable in QtBuildInternalsExtra.cmake.in
so it's propagated to leaf repositories as well.

There is no need for this variable to be stored in CMake's cache.  We

We still store QT_SYNCQT in a global property, because the function
qt_ensure_sync_qt is called in different directory scopes, and we want
to avoid re-calculations for every subdir.

It's now possible for the user to set QT_SYNCQT (see QTBUG-88088 for
motivation).  Also, in a non-prefix build, changes to syncqt.pl in the

3c1125d9fe CMake: Create plugin initializers for static user plugins
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.

Amends 91c65dd80c

As a result of the implementation change, cleanup example projects
to ensure that they build successfully (the important part is
specifying the CLASS_NAME).

Only plugandpaint works properly with both shared and static Qt
builds.

echoplugin works with a shared Qt build, but not a static one due to
some assumptions in the C++ code about shared plugins.

styleplugin doesn't seem to work properly neither with shared Qt
builds nor static Qt builds, at least on macOS. But it builds fine.
For some reason even if the plugin is found, the style is not applied.

6b6d42f6b8 CMake: Fix QT_ADDITIONAL_PACKAGES_PREFIX_PATH for cross-builds
The QT_ADDITIONAL_PACKAGES_PREFIX_PATH variable was introduced to
allow specifying extra locations to find Qt packages.

The reason it was introduced instead of just using CMAKE_PREFIX_PATH
is because the Qt6 component find_package call uses NO_DEFAULT_PATH
which means CMAKE_PREFIX_PATH is ignored.
We use NO_DEFAULT_PATH to ensure we don't accidentally pick up
system / distro Qt packages.

The paths from QT_ADDITIONAL_PACKAGES_PREFIX_PATH are added to the
find_package PATHS option in the Qt6 package, each
ModuleDependencies.cmake file and some other places.

Unfortunately that's not enough to make it work for cross-builds.

Imagine the following scenario.

  host qtbase, qtdeclarative installed in /host_qt
  target qtbase installed in /target_qtbase
  target qtdeclarative installed in /target_qtdeclarative

We want to cross-build qtlottie.

We configure qtlottie as follows
 /target_qtbase/bin/qt-configure-module /qtlottie_src -- -DQT_ADDITIONAL_PACKAGES_PREFIX_PATH=/target_qtdeclarative

We expect the target QtQuick package to be found, but it won't be.

The reason is that QT_ADDITIONAL_PACKAGES_PREFIX_PATH is added to the
PATHs option, but we don't adjust CMAKE_FIND_ROOT_PATH.

Without adding the new paths in CMAKE_FIND_ROOT_PATH, CMake will
re-root the passed PATHs under the existing CMAKE_FIND_ROOT_PATH,
which is QT_TOOLCHAIN_RELOCATABLE_INSTALL_PREFIX, which evaluates to
/target_qtbase. There is no QtQuick package there.

To fix this, prepend the values of QT_ADDITIONAL_PACKAGES_PREFIX_PATH
to CMAKE_FIND_ROOT_PATH.

The location where we currently do CMAKE_FIND_ROOT_PATH manipulations
is in the qt.toolchain.cmake file, so to be consistent, we prepend the
new prefixes there as well.

We need to adjust both CMAKE_FIND_ROOT_PATH and CMAKE_PREFIX_PATH,
due the path re-rooting bug in CMake.
See https://gitlab.kitware.com/cmake/cmake/-/issues/21937 as well as
the existing comment in qt.toolchain.cmake marked with
REROOT_PATH_ISSUE_MARKER.

We also need to do a few more things to make the setup work

Because Qt6Config uses NO_DEFAULT_PATH, the CMAKE_PREFIX_PATH
adjustments we do in the toolchain file are not enough, so we still need
to add the same prefixes to the Qt6Config find_package PATHS option.

One would ask why do we need to adjust CMAKE_PREFIX_PATH at all then.
It's for find_package(Qt6Foo) calls to work which don't go through
the Qt6Config umbrella package.

To make the CMake re-rooting behavior happy, we need to ensure the
provided paths are absolute.
So we iterate over the values of QT_ADDITIONAL_PACKAGES_PREFIX_PATH,
to make them absolute. We do the same for the environment variable.

We need to append lib/cmake to the prefixes which are added to
CMAKE_PREFIX_PATH, otherwise the CMake re-rooting bug is hit.

We need to specify the Qt6 package location (${_qt_cmake_dir}) to the
PATHS option in the various Dependencies.cmake.in files, to ensure
that dependency resolution can jump around between the Qt6 dir and
the additional prefixes. Previously the dependency lookup code assumed
that all dependencies would be within the same prefix.

The same is needed for qt and qml plugin dependency lookup.

e7455644a2 CMake: Don't install metatypes files for user projects
Installing extracted metatypes json files for user projects was an
oversight. We shouldn't install anything on behalf of user projects,
but rather give them enough information so they can do it the
themselves.

Make all the install options of qt6_extract_metatypes internal,
change the behavior not to install the files by default, unless
__QT_INTERNAL_INSTALL is passed, which is used for the Qt build only.

__QT_INTERNAL_NO_INSTALL is now a no-op and should be removed from
projects.

This is behavior change for existing public API, but it's better to
fix this now before 6.2.0 release.

Introduce a new OUTPUT_FILES option to allow assigning the extracted
metatype file paths into a variable that the project provides.
The project can then install the files where they need them.

[ChangeLog][CMake] qt6_extract_metatypes does not install metatypes
files anymore. Instead the OUTPUT_FILES option can be provided to get
the list of extracted files for further processing.

d2359b2d4e Pick up *Tools components also from host Qt
Let find_package(Qt6 COMPONENTS LinguistTools) for a cross-compiled

Furthermore adding ${QT_HOST_PATH}/lib/cmake to PATHS argument
makes sure that find_package will work even with NO_DEFAULT_PATH.

Make sure not to match ShaderTools and Tools packages.
ShaderTools is the cross-compiled package, the host package name is
ShaderToolsTools.
Tools is the cross-compiled module from qttools.

dfabb5b677 CMake: Use __qt_internal_propagate_object_library for static plugins
Address TODO and use the new helper
__qt_internal_propagate_object_library function instead of
target_sources when linking static plugin initializers via usage
requirements.

Note that to work correctly this depends on using the
target_link_options object library linking approach, which means a
minimum CMake version of 3.17, which is already the case for static
Qt usage.
With CMake 3.21, it will use target_link_libraries approach instead.

With CMake version 3.16 or lower, currently, this won't work correctly
on Linux if there are dependencies wrapped in genexes because the
__qt_internal_propagate_object_library call will try to use
the still-by-default-enabled 'object_libraries' finalizer mode via
__qt_internal_collect_dependency_object_libraries and that stops
the usage of the target_sources approach to link the object files
directly.

This isn't a big deal though, because we already require CMake 3.20
as the minimum.
It might be a bigger deal if we will need any of this functionality
to work with 3.16 in shared Qt builds where the user project tries
to create and link against custom static plugins. But that's already
likely to be a can of worms even without this specific edge case.

5161d8d525 CMake: Remove qt6_enable_object_libraries_finalizer_mode
qt6_enable_object_libraries_finalizer_mode is not needed anymore
now that static Qt builds require CMake 3.21 and thus CMake takes
care of placing object library object files at the beginning of
the link line.

Rename qt6_enable_import_plugins_finalizer_mode to a more generic
qt6_set_finalizer_mode that can enable or disable multiple
different modes.

For now the only available mode is "static_plugins" which handles
the behavior of the old function name.

The mode can be enabled by calling

 qt6_set_finalizer_mode(${target} ENABLE MODES "static_plugins")

Note that the function is re-tagged as being in Technical Preview.

Ideally we would not need it at all. But we need to provide some
workaround for the limitations of linking Qt static plugins in CMake
on Linux-y platforms that use bfd ld or ld.gold.

The workaround does not work well with dependencies wrapped in
generator expressions which is why we can't confidently advertise it
as a proper solution.
Our hope is that this can be fixed in future upstream CMake versions
and the function can be removed.
See 6fcc272ac9 for details.

Adjust the tests due to the renamed and removed functions.

Provide better error messages when a Qt package / component is not
found.

Mention the location of the expected Config file on the file system,
whether it exists
Also mention the location of the Config file that was specified by the
user when configuring the project or which CMake computed and stored
in QtModule_DIR cache var.

Mention that a package is not found in case if the main target exposed
by that package is not found.

If the target is not found, mention that it might be due to
QT_NO_CREATE_TARGETS being set to TRUE (when it is set to true).
If it is set to true, the assumption is that the target must have been
defined by something else before the find_package call (either an
earlier find_package call without QT_NO_CREATE_TARGETS set to TRUE or
maybe it's the use case of Qt being built together with its examples
or it's a super build).

Unset _Qt_NOTFOUND_MESSAGE to ensure that the Qt6 not found error
message is not spilled into any subsequent find_package(Qt6) calls,
causing a cascade of unwarranted warnings / errors.
Make sure to unset it only if components were specified, so the
message is not shown or unset in any of the recursive
find_package(Qt6) calls which is a dependency for regular Qt module
packages.
This works fine, because find_package(Qt6) calls with components are
only done in project code and not done by the transitive dependency
code (which looks for Qt6Foo packages directly).

6518bcc167 CMake: Enforce minimum CMake version in user projects
This change introduces new behavior to error out when configuring user
projects if the CMake version used is too old for Qt to work with.

The main motivator is the requirement of new CMake features to ensure
object libraries are placed in the proper place on the link line in
static builds.

The minimum CMake version is computed based on whether Qt was
configured as shared or static libraries.

At the moment the required versions for building and using Qt are the
same.

The minimum versions are defined in qtbase/.cmake.conf in the
following variables

QT_SUPPORTED_MIN_CMAKE_VERSION_FOR_BUILDING_QT_SHARED
QT_SUPPORTED_MIN_CMAKE_VERSION_FOR_BUILDING_QT_STATIC
QT_SUPPORTED_MIN_CMAKE_VERSION_FOR_USING_QT_SHARED
QT_SUPPORTED_MIN_CMAKE_VERSION_FOR_USING_QT_STATIC

Qt Packagers can disable the version check when configuring Qt
by setting
QT_FORCE_MIN_CMAKE_VERSION_FOR_BUILDING_QT and
QT_FORCE_MIN_CMAKE_VERSION_FOR_USING_QT.

In this case it is the packagers responsibility to ensure such a Qt
works correctly with the specified CMake version.

User projects can also set QT_FORCE_MIN_CMAKE_VERSION_FOR_USING_QT
to disable the version check. Then it's the project's developer
responsibility to ensure such a Qt works correctly.

No official support is provided for these cases.

Implementation notes.

The versions required to build Qt are stored in
QtBuildInternalsExtra.cmake
whereas the versions required to use Qt are stored in a new
QtConfigExtras.cmake.

Also the policy range variables stored in
QtBuildInternalsExtra.cmake are now regular variables instead of cache
variables, to properly allow overrides per-repository.

Some renaming of functions and variables was done for a bit more
clarity and easier grep-ability.

minimum CMake version of 3.20.

Qt builders and packagers can still opt out of the mentioned minimum
required version by configuring Qt with QT_FORCE_MIN_CMAKE_VERSION.
Such a Qt configuration is /NOT SUPPORTED/.

To facilitate these changes, the minimum version check has been moved
to happen after the BUILD_SHARED_LIBS option is computed by either
QtAutoDetect.cmake or set by a user provided cmake toolchain file.

Introduce a new QT_MIN_SUPPORTED_CMAKE_VERSION_FOR_STATIC_QT variable
in .cmake.conf to mark the minimum version for a static Qt build.

3c23317552 CMake: Make WrapVulkanHeaders target optional for QtGui consumers
If Vulkan headers are present on the system when qtbase is configured,
QtGui and QtOpenGL should be compiled with Vulkan support.

If a user project uses a Qt built with Vulkan support, but their system
is missing Vulkan headers, the project configuration needs to succeed.

The project will get compilation errors if it uses Vulkan headers, but
that's intended.

This use case was broken when fixing Vulkan to be found when building
Qt for Android.

Fix the regression with a combination of things
1) Mark the WrapVulkanHeaders package as optional (already the case)
2) Use the include directories directly when compiling Gui and OpenGL
3) Propagate WrapVulkanHeaders::WrapVulkanHeaders link requirement to
   consumers only if the target exists. It won't exist if Vulkan
   include dirs are not found

This also requires some changes in pri and prl file generation.

For prl file generation, we don't want to link to the
WrapVulkanHeaders target, so we filter out all dependencies that
use TARGET_NAME_IF_EXISTS for anything that calls
__qt_internal_walk_libs which includes qt_collect_libs.

For pri files, we make sure to generate a uses=vulkan/nolink clause
by inspecting a new _qt_is_nolink_target property on the target.

We also don't add include dirs to the pri file if the new
_qt_skip_include_dir_for_pri property is set.
This is intended for Vulkan, because there is separate qmake logic to
try and find the include dirs when configuring a user project.

As a drive-by, fix nolink handling for WrapOpenSSLHeaders.

42970e490a CMake: Bump min required CMake version for shared Qt builds to 3.16
Building a shared library Qt configuration already required a minimum
CMake version of 3.16, because we depend on CMake's Autogen.json files
which are used for metatype.json file generation.

If a lower version was used, a FATAL_ERROR was issued in
qt6_extract_metatypes.

This change is essentially moving the check to happen earlier in the
qtbase configure process.

User projects will now /also/ officially require a minimum of 3.16
(up from 3.14).

As a consequence, the min/max version policy range that is set in
the public QtFooConfig.cmake files is changed
from 3.14..3.19
to   3.16..3.20

The upper bound is raised because building and using Qt works fine
with all CMake 3.20 policies set to NEW.

[ChangeLog][CMake] Building Qt as shared libraries now requires
CMake version 3.16 or later. Building user projects with CMake using
that Qt installation also requires a CMake version of 3.16 or later.

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.

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.

We shouldn't force add the bitcode linker flags to user projects.
And we don't link anything when building Qt for iOS itself, we only
archive object files into static libraries.

The final decision whether bitcode should be used is up to the Xcode
project. That is controlled by Xcode's ENABLE_BITCODE option.

Bitcode compile flags are still added when building Qt itself.
