When CMP00126 is set to NEW, set(CACHE) doesn't remove regular
variable bindings with the same name as the cache variable.
This introduced an issue in qt_find_package, which called
find_package(CONFIG QUIET) to try and find a package config file, but
did not clean up the non-cache _FOUND variable which is automatically
set to 0 by CMake if no Config file is found.
Make sure to unset both the regular and cache _FOUND variables if either
the package config file was not found, or if none of the provided
targets found even if the Config file was found.
Also move the _DIR cache variable cleaning into the same code block.

CMake master / 3.22 introduced a behavior change in how conditions are
evaluated in the while command. It is now consistent with how if()
evaluates conditions.
This caused an issue in Qt code where a "(" opening parenthesis was

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

Also mention the location of the Config file that was specified by the
user when configuring the project or which CMake computed and stored

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

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.

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.

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.

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.

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.
