Configure Qt with -DQT_FEATURE_headersclean=ON to enable the
check. There will be separate target for each module include
(e.g. QtCore_header_check), but the check will also be done
when the module is built for the first time.
There are notable differences to the qmake version:
- the build does not pick up anymore default defines or flags from
the module, or Qt. Instead options like -fPIC they have to be listed
explicitly. Also for this reason, we have to skip the vulkan-related
headers from the check, since vulkan/vulkan.h is not necessarily
in the compiler's default search path.
- some checks for nowadays unsupported compiler versions are
removed.
- -Wdouble-promotion -Wshorten-64-to-32 is not added for clang
builds; the qmake code path did never enforce that on CI
machines (it was non-Apple clang only), and the check currently
fails on these configurations.

The endless saga of fighting with qt_find_package and global target
promotion. In certain scenarios we want to opt out of target promotion
to global scope.
One such case is in qttools with WrapLibClang and Threads::Threads.
Threads::Threads will be found in the top-level scope via
Qt6Dependencies.
WrapLibClang is declared in src/ directory scope, and
then we try to promote it ands its dependencies to the global scope,
via qt_find_package() ->
qt_find_package_promote_targets_to_global_scope().
This fails because we can't promote Threads::Threads due to it being
added in a different subdirectory scope.
Introduce 2 new functions.
qt_internal_should_not_promote_package_target_to_global and
qt_internal_disable_find_package_global_promotion.
The first one is used to disable promotion of targets to global scope
in qt_find_package.
To mark a target not to be promoted, the second function is used.
It will be used by qttools for the WrapLibClang case.

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.

For qt_import_qml_plugins to work, it needs to have access to the Qml
plugin targets by the time find_package(Qt6Qml) is called.
To do that, we modify the generation of Qml plugin Config, Targets and
Dependencies files to go into a special 'QmlPlugins' subfolder of the
Qml package.
The Qml package will then GLOB include all the Config files in that
folder, to make them available whenever find_package(Qt6Qml) is
called.
This is similar to how the Qt plugins were glob included in the CMake
integration of Qt 5.15. In fact that glob including is missing in Qt 6
for regular Qt plugins, and should be implemented in a following
change. Currently the Qt Plugins config files that are included are
hardcoded to the list of known plugins at Qt configuration time.
As a drive-by to make this all work, the naming of the various Config
and Dependencies files has been normalized to include the Qt6 prefix.
This is done for both regular Qt plugins and Qml plugins.

Static Qt plugins should not be included in the list of libraries of
a prl file. They end up being there due to our circular dependency
trick where the plugins depend on the module they belong
to.
This in turn causes the giant static plugin generator expressions to
be processed in qt_collect_libs(), and the generated prl file ends up
having target names like Qt6::QJpegPlugin which are obviously not
linker flags.
To eliminate the static plugins from prl files, add an additional
dummy boolean generator expression '$<BOOL:QT_IS_PLUGIN_GENEX>'
that always evaluates to true. We can string match on this expression
in qt_collect_libs, and thus remove the whole static plugin genex
entry.
This should fix linking of apps with qmake that use a CMake-built
static Qt.

mkspecs/features/qt.prf adds a dependency on the system threading

loaded by any public or internal Qt project, it's essentially a public
dependency for any Qt consumer.
To mimic that in CMake, we check if the thread feature is enabled, and
and set the Threads::Threads library as a dependency of Qt6::Platform,
which is a public target used by all Qt modules and plugins and Qt
consumers.
We also need to create a Qt6Dependencies.cmake file so we
find_package(Threads) every time find_package(Qt6) is called.
For the .prl files to be usable, we have to filter out some
CMake implementation specific directory separator tokens
'CMAKE_DIRECTORY_ID_SEP' aka '::@', which are added because we call
target_link_libraries() with a target created in a different scope

The logic is a bit involved in qmake.
The Qt internal qt_common.prf adds CONFIG += strict_c++ which applies
to qt modules, qt plugins, qml plugins, qt helper libs, winmain and
qt_apps, qt_tools, but NOT tests (which is important because the tests
on Windows MinGW fail to build without the GNU extensions).
Then default_post.prf checks for the strict_c++ value and either uses
the strict or non-strict C++ standard flags. default_post.prf is
loaded for all qmake projects, not just the Qt internal ones.
Now CMake doesn't provide a transitive based option to disable C++
GNU extensions with a mechanism similar to target_compile_features.
It only provides the CXX_EXTENSIONS property and it's associated
CMAKE_CXX_EXTENSIONS variable. We can't set the variable at a
directory scope, because that is too coarse grained.
So we rely on setting the property via a function in every relevant
qt_add_<target> function.
Now the naming of the function is weird.
We name the function as qt_internal_<...>, because it's not meant to be
used by Qt users.
We prepend an underscore to the name because we need to place it in
Qt6CoreMacros, so that the function can be called by
qt_add_qml_module which IS a public function.
That's because in Qt5 load(qml_plugin) was private API, but in Qt 6 +
CMake we decided to make qt_add_qml_module() as public API.

On Windows, if Qt is built with Vulkan support but the user's machine
does not have Vulkan, it should still be possible to configure and
build an application (if the application does not use Vulkan of
course).
When Qt is built with qmake, the special windows_vulkan_sdk.prf file
makes sure not to export build time Vulkan include headers into the
generated .pri files. The same file also tries to find the include
headers via an environment variable. If it isn't set, it just adds a
bogus "/include" include path, which doesn't fail a user's application
build.
This wasn't the case for an application built with CMake, because the
exported Vulkan_nolink target uncodinitionally referenced Vulkan's
target properties. Which means that if the Vulkan package was not
found, the application failed to configure.
To mimic qmake's behavior, make sure to query the target properties
only if the Vulkan target exists, via the TARGET_EXISTS generator
expression.
Apply the same logic to all _nolink targets. This might not be
entirely correct in all cases, but we can revise this behavior later
after more feedback. At the very least it allows building non-Vulkan
based applications.

by qmake (and not QtCore's QLibraryInfo) to determine the ext prefix

In the qmake build of Qt, qmake considers the host prefix as "location
where qmake is installed". This is usually the same as the ext prefix
but can be modified by the user at configure time.
In the CMake build, we don't build tools for the host but always for
the target platform. The QT_HOST_PATH is an external prefix we never
install to. That means, the qmake we build is always installed into
the ext prefix (CMAKE_STAGING_PREFIX or CMAKE_INSTALL_PREFIX).
Therefore, we can calculate the path of <ext_prefix>/bin relative to
<ext_prefix> and use this value for both,
QT_CONFIGURE_HOSTBINDIR_TO_HOSTPREFIX_PATH and
QT_CONFIGURE_HOSTBINDIR_TO_EXTPREFIX_PATH.
The "path of <ext_prefix>/bin relative to <ext_prefix>" is equivalent to
just the "path <prefix>/bin relative to <prefix>", meaning we can

PKG_CONFIG_EXECUTABLE, because there is no other good way. The
downside to this is that a lot of warning messages will be printed
that the pkg-config package can not be found.
The pkg-config feature needs to be computed in QtBuildInternals before
qtbase/src/configure.cmake, because it's too late to do it in that
file where a few qt_find_package calls already exist.
The feature value is also saved to QtBuildInternalsExtra, to make sure
that pkg-config is disabled whenever building another repo.
System prefix adjustment is done by removing paths from
CMAKE_SYSTEM_PREFIX_PATH.
Ideally we would remove also /usr as a path, to match what qmake does,
but that breaks find_program() calls for perl, python, etc.
We have to make sure that qt_find_package does not look in
PATH when looking for packages, which is the default behavior, because
PATH on macOS most likely contains /usr/local.
One last curiosity for future generations is that CMake 3.18+ has
merged a change to prioritise SDK locations over regular /usr/lib.

This adds the CMake equivalent to the classical -device-option key=value
configure argument:
-DQT_QMAKE_DEVICE_OPTIONS=key1=value1[;keyN=valueN]
The keys and values get dumped verbatim into qdevice.pri.
This patch also ports the machineTuple configure test. Its result is
written into qdevice.pri as value for the GCC_MACHINE_DUMP variable.

It's now possible to pass -DQT_QMAKE_TARGET_MKSPEC=foo to cmake. If the
value is not passed, then we will guess the mkspec like we did before.

For a cross-built, gcc-built Qt, the qmake build writes code into
qconfig.pri that adds the --sysroot flag to compiler and linker flags.
Follow suit in the CMake build.
To keep the diff small between the qmake-generated and CMake-generated
qconfig.pri files, the sysroot code is added at the top of
qconfig.pri, which is the reason for the new 'content' string variable.

When cross-compiling, we now create a target_qt.conf file that's to be
used with the host Qt's qmake. With "qmake -qtconf .../target_qt.conf"
projects can be cross-built against the cross-built Qt.
We also create wrapper scripts for the host qmake to save the user from
passing the -qtconf argument.

Before this change, the qt_lib_foo_private .pri files contained
absolute paths to libraries, e.g.
/usr/lib/x86_64-linux-gnu/libcups.so
Whereas the qmake build instead embeds link flags like -lcups.
Detect absolute library file paths, and transform them into link
flags. This should make the .pri files relocatable.
Fix the add_custom_commands to have the scripts as dependencies.
Make sure to pass the suffix, prefix and other options to the
qconfig.pri generation command as well.
Also reverse the order of the link flags, to mirror the order
that qmake generates for .pri files.

In a prefix build, this function uses install(PROGRAMS) which correctly
sets the executable bit. In a non-prefix build, we did file(COPY)
without explicitly setting executable permissions.
Now, we're also setting the executable bit for
qt_copy_or_install(PROGRAMS) calls in non-prefix builds.

A developer could write 'ninja host_tools' to build the qtbase tools
and their dependencies, and then configure another cross-compiling
build dir pointing to the previous host build. This shortens the
workflow for cross-building when working in qtbase.

Rather than embedding the full absolute path to the framework, we
should instead write a -framework Foo flag.
qmake seems to do this by specifying QMAKE_LIBS_FOO in the mkspec.
We'll try to get away with just deriving the name of the framework
from the path, to avoid having to introduce a mkspec equivalent
mapping for CMake.
This doesn't currently handle framework include paths, which qmake
also handled by harcoding QMAKE_INCDIR_FOO in the mkspec, and then
sysrootifying it via mkspecs/common/mac/sdk.prf.
Hopefully that's not really needed, given that -framework flag
should imply include paths as well.

Otherwise the Objective-C++ sources will be built with the default
compiler visibility (visible), and then linked with moc-generated
C++ sources that have the Qt overridden hidden visibility, resulting
in linker warnings such as:
ld: warning: direct access in function 'X' from file 'moc_foo.cpp.o'
to global weak symbol 'Y' from file 'bar.mm.o' means the weak symbol
cannot be overridden at runtime. This was likely caused by different
translation units being compiled with different visibility setting
