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.

60f36007a3 CMake: Don't cache QT_SYNCQT across builds
There is no need for this variable to be stored in CMake's cache.  We
don't perform expensive operations to set up QT_SYNCQT, and we even
unset the cache variable to ensure it gets recomputed on
reconfiguration.

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
source dir are reflected upon re-configuration in the build
tree (because qt_copy_or_install is called on every configure).

e1fe816d46 Implement generating of private cpp exports
Add the generating of private cpp exports for Qt modules.

Add the GENERATE_PRIVATE_CPP_EXPORTS option to qt_internal_add_module
that is the manual switch for private exports generator. Existing
modules in qtbase doesn't follow any strict convention of using
private cpp export. So there is no clue how to detect if generating of
the private exports is required or not for the module.

Use autogenerated private cpp exports in QtNetwork module.

CPP_EXPORT_HEADER_NAME argument of the qt_internal_add_module function
is replaced by the CPP_EXPORT_HEADER_BASE_NAME and has a different
meaning. The provided name is used as a base name for the private and
non-private headers that contains cpp exports. Header files suffixes
are constant: .h and _p.h for the non-private and private header files
accordingly.

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.

which was supposed to separate the arguments and write them into
config.opt.

However, passing arbitrary arguments after "-P script.cmake" only worked
by accident and is not supported.  As soon as arguments are passed that
are valid CMake arguments, like -help or -G, the CMake call would fail.

Now, we let configure.bat and qt-configure-module.bat write the
arguments as is into config.opt.in and let QtWriteArgsFile.cmake read

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

__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.

files anymore. Instead the OUTPUT_FILES option can be provided to get
the list of extracted files for further processing.

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.

825cb50c27 CMake: Improve component / package not found error messages
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.

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.

In CMake it can be achieved by either adding the compiler and link flags

451733bd57 CMake: Fix reconfiguration error when features have EMIT_IF conditions
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
conditions were met).

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
that a feature value has changed.

Make sure to not save the user provided value for a non-emitted
feature and to always set its internal feature value to OFF.

e80b010795 Use target_link_options to propagate object libraries
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.

c72b7b8e5e Revert "Make toolchain inspection more robust"
This reverts commit 7c62caa355.

Certain toolchain files cannot be read in CMake script mode with CMake
versions >= 3.20.

For example, the vcpkg toolchain file overrides add_executable, and
that fails with CMake 3.20:
CMake Error at D:/dev_tools/vcpkg/scripts/buildsystems/vcpkg.cmake:662 (function):
 Built-in flow control command "add_executable" cannot be overridden.

bb25536a3d CMake: Fix Vulkan to be found when targeting Android
Introduce two new packages WrapVulkanHeaders and WrapVulkan similar to
the OpenSSL wrapper packages.

WrapVulkanHeaders uses FindVulkan and is marked as found if Vulkan
headers are found (that's the only part the Qt build requires).

The WrapVulkan package is currently not used, but is there for
symmetry.

The Vulkan feature is now disabled by default on QNX, because the
QNX toolchain file in the CI does not set
CMAKE_FIND_ROOT_PATH_MODE-like variables and CMake ends up finding
host Vulkan headers causing the build to break.

82063d9af1 CMake: Pierce through LINK_ONLY deps in finalizer dep traversal
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
approach is still broken.

1981682687 CMake: Propagate sanitizer flags to public projects
Ensure that Qt user projects build with sanitizer flags if Qt was
configured with any of the sanitizers enabled.

To compile Qt with sanitizer support enable any of Qt sanitizer
features.

Passing -DECM_ENABLE_SANITIZERS=address to CMake is NOT supported
anymore.

When configuring Qt using CMake directly, pass
    -DFEATURE_sanitizer_address=ON
    -DFEATURE_sanitizer_undefined=ON
instead of
    -DECM_ENABLE_SANITIZERS=address;undefined

When configuring Qt with the configure script pass
    -sanitize address -sanitize undefined
as usual.

QtConfig.cmake now records the sanitizer options that should be
enabled for all consuming projects based on the enabled Qt features.
This applies to internal Qt builds as well as well as tests an
examples.

The recorded sanitizer options are assigned to the ECM_ENABLE_SANITIZERS
variable in the directory scope where find_package(Qt6) is called.
The ECMEnableSanitizers module is included to add the necessary flags to
all targets in that directory scope or its children.

This behavior can be opted out by setting the
QT_NO_ADD_SANITIZER_OPTIONS variable in projects that use Qt and might
be handling sanitizer options differently.
