If find_package(Qt6 REQUIRED COMPONENTS Core) is called, don't
propagate the REQUIRED option to all the dependencies of Core,
regardless if it's a 3rd party library, tool or another Qt package
dependency.
Propagating REQUIRED causes the find_dependency -> find_package call
to exit the calling file immediately when the package is not found,
not giving an opportunity for find_dependency to set the
_NOT_FOUND_MESSAGE variable.
Instead force all find_dependency / find_package calls
to be optional, set the calling _FOUND variable to FALSE if the
dependency is not found, also set the _NOT_FOUND_MESSAGE variable.
Then the find_package call that loaded FooModuleConfig.cmake file
will show that message as the reason for the package not being

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.

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.

In cmake, targets are used as an entity for modules. This causes a
number of problems when we want to manipulate a module as a separate
entity with properties associated with it.
The _qt_internal_module_interface_name target property is introduced to
represent the module entity. All modules write a name to this property,
which will subsequently expand into the module name matched with
the module name in qmake.
The 'qt_internal_module_info' function is responsible for providing the
correct values for the module properties used when working with a module
target.
Unlike qmake, for internal modules in cmake it is expected that the
Private suffix will be specified explicitly. In case the user wants to
have a different module name, an additional argument
MODULE_INTERFACE_NAME of the qt_internal_add_module function is
introduced.
This also changes the way how target dependencies are collected and
resolved. Since the 'Private' suffix no longer means an unique
identifier of the module 'Private' part, we look for the both Private
and non-Private package names when resolving dependencies.
TODO: This change doesn't affect the existing internal modules, so to
keep compatibility with the existing code the existing internal modules
create 'Private' aliases. The code that provides backward compatibility
must be removed once all internal modules will get the proper names.

By default, when using the Qt6 CMake package to look for components,

ensure that CMake doesn't accidentally find system (distro) packages.
Instead we limit the paths to one level up from where the Qt6 package
is.
Unfortunately that doesn't quite work for finding Qt packages that
might have been installed into a different prefix than where the main
Qt prefix is.
This happens when Qt addons are built by Conan, and installed into
a separate prefix.
To allow calls like find_package(Qt6 COMPONENTS ConanAddon) to work
in a scenario as described above, introduce a new variable called
QT_ADDITIONAL_PACKAGES_PREFIX_PATH which can be used to specify
additional paths where Qt CMake packages should be found.
This is similar to previously introduced QT_EXAMPLES_CMAKE_PREFIX_PATH

Additionally, allow disabling the NO_DEFAULT_PATH option by setting

Our initial approach to looking for host Qt tools when cross-compiling
to a platform with a different architecture bitness compared to the
host one was to unset CMAKE_SIZEOF_VOID_P before calling
find_package(Qt6FooTools) and then restoring the value.
That works to bypass the architecture bitness test in the
ConfigVersion files, but it also influences the paths that
find_package() searches in, specifically the lib<arch> paths like
/usr/lib64 will not be searched in.
Fortunately since CMake 3.14, write_basic_package_version_file() can
take an additional ARCH_INDEPENDENT parameter. This disables the
architecture bitness test when looking for the package, while allowing
to still search in the /usr/lib64 like paths.
Use it when creating the QtFooToolConfigVersion.cmake files.
One could argue we should actually check if the tool executables could
run on the host system where find_package is called for
cross-compilation.
We could do that in another change if the problem ever arises.

While trying to implement the 'host artifact reuse' Coin instructions
change, a bug surfaced where the qemu configurations didn't find
the host tools and instead tried to use the cross-compiled tools
while building qtbase, which failed due to not finding the
runtime linker (another unsolved issue).
Before the host artifact reuse change, the host tools were found
successfully.
The difference that caused the issue is that the target install prefix
was a direct subfolder of the host prefix.
host - /home/qt/work/qt/install
target - /home/qt/work/qt/install/target
Before the host reuse change the install prefixes were as follows
host - /home/qt/work/qt/install/host
target - /home/qt/work/qt/install/target
While looking for the Qt6CoreTools package, we temporarily set
CMAKE_FIND_ROOT_PATH and CMAKE_PREFIX_PATH to contain first
'/home/qt/work/qt/install' and then '/home/qt/work/qt/install/target'.
CMake then reroots the CMAKE_PREFIX_PATH values onto values in
CMAKE_FIND_ROOT_PATH, making an MxN list of prefixes to search.
Rerooting essentially means concatenating 2 paths, unless the
considered prefix is a subfolder of the root path.
What happened was that the first considered value was
'/home/qt/work/qt/install/home/qt/work/qt/install', a non-existent
location that gets discarded.
The second considered value was '/home/qt/work/qt/install/target.
The second value is the result of seeing that
'/home/qt/work/qt/install/target' is a subfolder of
'/home/qt/work/qt/install' and thus the root path is stripped.
All of this is done in cmFindPackageCommand::FindConfig() ->
cmFindCommon::RerootPaths.
The behavior above caused the target tools be found instead of the
host ones.
Before the host reuse change, both of the initial constructed prefixes
were discared due to them not existing, e.g.
'/home/qt/work/qt/install/target/home/qt/work/qt/install/target'
and '/home/qt/work/qt/install/host/home/qt/work/qt/install/host'
One of the later prefixes combined CMAKE_FIND_ROOT_PATH ==
'/home/qt/work/qt/install/host' + CMAKE_PREFIX_PATH == '/' resulting
in '/home/qt/work/qt/install/host/' and this accidentally found the
host tools package.
We actually stumbled upon this issue a while ago when implementing Qt
5.14 Android CMake support in 52c799ed44
That commit message mentions the fix is to add a "lib/cmake"
suffix to the PATHS option of find_package().
This would cause the subfolder => strip root behavior mentioned
above.
So finally the fix.
First, make sure not to append QT_HOST_PATH in the toolchain file,
there shouldn't be any need to do that, give that we temporarily set
it when looking for Tools packages.
Second, recreate the subdir scenario in the Qt toolchain file by
setting CMAKE_FIND_ROOT_PATH to the current (relocated) install
prefix as usual, but also setting CMAKE_PREFIX_PATH to a new value
poining to the CMake directory.
Aka '/home/alex/qt' and '/home/alex/qt/lib/cmake'.
Third, when a QT_HOST_PATH is given, save 2 paths in the generated Qt
toolchain: QT_HOST_PATH and QT_HOST_PATH_CMAKE_DIR. There are the host
equivalents of the target ones above. Use these values when looking
for host tools in Qt6CoreModuleDependencies.cmake, again facilitaing
the subdir behavior.
Note these are currently absolute paths and are not relocatable.
We'll have to figure out if it's even possible to make the host path
relocatable.
Finally as a cleanup, look for the Qt6HostInfo package in QtSetup
strictly in the given QT_HOST_PATH, so CMake doesn't accidentally find
a system Qt package.

To build examples as part of a non-installed Qt prefix build,
not-yet-installed Config files need to be found by find_package()
calls inside example projects.
Facilitate that by propagating the CMAKE_PREFIX_PATH and
QT_EXAMPLES_CMAKE_PREFIX_PATH paths in all relevant find_package()
calls where NO_DEFAULT_PATH is used.
Also adjust the inclusion of the QtFeature.cmake file to be relative
to the qt6 directory, rather than the current list directory.
This is needed to successfully find the file when parsing a Config
file from a non-installed build directory.

For ICU we have multiple components, and ICU becomes a public dependency
to QtCore.
When storing the INTERFACE_QT_PACKAGE_COMPONENTS property, make sure to
store the entire list of components, not just the first component -- by
turning the semi-colon separated list into a space separated list.
When processing the components at find_dependency time, we need to
reverse that and pass COMPONENTS directly to ensure a correct parameter
expansion.

When the host system uses 64-bits for pointers and the target 32-bits,
then locating the tools dependencies would fail due to the mismatch.
Since the tools dependencies don't create linkable targets but merely
import executables, we can skip this check like in commit
914b367c7f.

This changes many different CMake places to mention Qt6 instead of
Qt5.
Note that some old qt5 cmake config files in corelib are probably not
needed anymore, but I still renamed and kept them for now.

In particular, Qt targets extended with other qt targets
(eg. Qt::VulkanSupport or Qt::LinuxAccessibilitySupport)
after the first add_qt_module were not taken into account when generating
Depends files.
Note that this patch updates the minimum required version
to CMake 3.15

Also make the tool package depend on all tool packages that correspond
to the qt module dependencies.
So find_package(Qt5Widgets) implicitly calls find_package(Qt5WidgetTools).
And find_package(Qt5WidgetsTools) will call find_package for
Qt5GuiTools, and Qt5CoreTools.
This enhances the user experience, so that in modules like qtsvg, you
don't have to specify both find_package(Qt5Widgets) and
find_package(Qt5WidgetsTools), but only the former.
Or when cross building, you only need to specify Qt5WidgetTools, to get
both Core and Gui tools.

This change introduces a new function called qt_find_package()
which can take an extra option called PROVIDED_TARGETS, which
associates targets with the package that defines those targets.
This is done by setting the INTERFACE_QT_PACKAGE_NAME and
INTERFACE_QT_PACKAGE_VERSION properties on the imported targets.
This information allows us to generate appropriate find_dependency()
calls in a module's Config file for third party libraries.
For example when an application links against QtCore, it should also
link against zlib and atomic libraries. In order to do that, the
library locations first have to be found by CMake. This is achieved by
embedding find_dependency(ZLIB) and find_dependency(Atomic) in
Qt5CoreDependencies.cmake which is included by Qt5CoreConfig.cmake.
The latter is picked up when an application project contains
find_package(Qt5Core), and thus all linking dependencies are resolved.
The information 'which package provides which targets' is contained
in the python json2cmake conversion script. The generated output of
the script contains qt_find_package() calls that represent that
information.
The Qt5CoreDependencies.cmake file and which which dependencies it
contains is generated at the QtPostProcess stop.
Note that for non-static Qt builds, we only need to propagate public
3rd party libraries. For static builds, we need all third party
libraries.
In order for the INTERFACE_QT_PACKAGE_NAME property to be read in any
scope, the targets on which the property is set, have to be GLOBAL.
Also for applications and other modules to find all required third
party libraries, we have to install all our custom Find modules, and
make sure they define INTERFACE IMPORTED libraries, and not just
IMPORTED libraries.
