aa4a1006cb Refactor qt_internal_add_plugin() and qt6_add_plugin()
Remove code duplication by calling qt6_add_plugin() from
qt_internal_add_plugin().

Separate out the public and internal arguments for the
variables defined in QtBuild.cmake for these functions.
Provide them via commands instead for greater robustness.
This separation allows other Qt repos to access the appropriate
set of keywords where they define commands that forward
on to *_add_plugin() in their implementations. Retain
the old variables for now to simplify the integration
steps for updating other repos. The old variables can
be removed once there are no more references left to
them in any repo.

78a64e310e qtdeclarative now directly handles more qml-specific logic
Associated changes in the qtdeclarative repo now ensure that arguments
for qml plugins are handled on the calling side. This reduces the
qml-specific logic needed in qtbase and gives qtdeclarative clearer
control over qml build and install locations.

As part of that work, the INSTALL_LOCATION keyword used in
qt_internal_record_rcc_object_files() has been renamed to
INSTALL_DIRECTORY to make it consistent with the keyword used for the
same concept in other commands.

43c28aa904 Use Core library for qmake instead of the Bootstrap library
Move the qmake-specific logic of the QLibraryInfo class to
qmake internals. 'qconfig.cpp.in' now stores information about
the library info entries to keep them consistent between qmake
and the Core library. qmake requires specific features enabled
in the Core library, so building qmake will be skipped if the
features are not enabled.

All flags directly related to the qmake have been removed from
Core lib.

a543e8f42e Fix QT_TOOL_PATH_SETUP_COMMAND
Commit 18fc9e1bf8 introduced a
Windows-only QT_TOOL_PATH_SETUP_COMMAND to make it possible to
call the tool of a module while building the module itself.
The "set PATH=..." command in QT_TOOL_PATH_SETUP_COMMAND was flawed,
because it contained escaped double quotes which made the set command ineffective.

Fix this by removing the escaping of the double quotes.
This was uncovered when porting qtscxml to CMake.

0274daf307 CMake: Rename QtBuildInternalsAndroid.cmake to QtAndroidHelpers.cmake
...and include it in QtBuild.cmake.

Commit e8d8b1a5e4 added two different code paths to include
QtBuildInternalsAndroid.cmake.

This was needed, because:

In a top-level build, we must not include files that are not yet
installed.  We have the source tree available, and
"${QT_SOURCE_TREE}/cmake" is in CMAKE_MODULE_PATH.
We can use the "module syntax" of the include() command.

In a per-repository build, when building against an installed qtbase, we
must not include files of the source tree, because that's not guaranteed
to be available.  However, Qt6BuildInternalsConfig.cmake is installed,
and we can directly include QtBuildInternalsAndroid.cmake, which is
right next to it.

We can circumvent this whole issue by moving the Android-related
functions out of the Qt6BuildInternals package and including it in
QtBuild.cmake.

For top-level builds it's desirable to have "ninja generate_docs" build
all tools needed to generate the documentation.

This is problematic since the doc-generating targets are created before

the doc tool target is not yet available.

This patch adds the functions qt_internal_defer_dependency and
qt_internal_add_deferred_dependencies.

c6a5cdcee6 CMake: Introduce Qt6::Startup target
Add an abstraction over Qt::WinMain (aka qtmain.lib) and
iOS's runtime linker entry point (_qt_main_wrapper).

The Core target will now link against the Startup target on all
platforms, instead of just WinMain on Windows.

The creation and linkage interface definition of the Startup target
is done at find_package(Qt6Core) time via the private call of
_qt_internal_setup_startup_target().

This will add automatic linkage of WinMain to executables marked with
the WIN32_EXECUTABLE property on Windows.
As well as the addition of the '-Wl,-e,_qt_main_wrapper' linker flag
when linking iOS executables.

Qt users can opt out of this behavior by either setting the
QT_NO_LINK_QTMAIN property or variable. This is in line with
Qt 5 behavior.

db21bad936 Port headersclean check to CMake
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.

57b94b58df CMake: Allow opting out of global target promotion
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.

9e044765ec CMake: Fix empty value of CMAKE_SIZEOF_VOID_P when looking for tools
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.

81ea5f1906 CMake: Prepare ground work for static Qml plugins importing
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

d50a7d635c CMake: Fix prl files of static Qt builds
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.

92ee9bd6b8 CMake: Properly handle CONFIG += thread aka Threads::Threads
mkspecs/features/qt.prf adds a dependency on the system threading
library if the Qt Core thread feature is enabled. Because qt.prf is
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
(I think).

As a result of this change, we shouldn't have to hardcode
Threads::Threads in other projects, because it's now a global public
dependency.

f69dbb0b41 CMake: Don't use std=gnu++11 when building Qt internal targets
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.

add_custom_command does not support generator expressions in OUTPUT

7b9904849f CMake: Fix _nolink targets to be optional on the consumer side
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.

1048d83fc2 Limit OpenGL deprecation silencing on Apple platform to Qt itself

we are aware of, so we don't need to see the warnings when building

Instead of applying the silencing globally for all Qt consumers,
both internal and external, we now limit the silencing to Qt itself.
That means user code that explicitly uses any of the deprecated APIs
will see the warnings. Note that this does not apply to merely using
any of the Qt OpenGL APIs. The user has to explicitly use the platform
APIs that have been deprecated.

The warnings need to be disabled on a build system level, so that
that they are passed as -D flags on the command line. If the defines
were done in Qt headers (qguiglobal.h e.g.), they would require the
user to always include this header before any of the Apple headers.

This patch modifies the two preprocessor definitions
QT_CONFIGURE_HOSTBINDIR_TO_HOSTPREFIX_PATH and
QT_CONFIGURE_HOSTBINDIR_TO_EXTPREFIX_PATH which are exclusively used
by qmake (and not QtCore's QLibraryInfo) to determine the ext prefix
and the host 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
safely use <prefix>, which is just CMAKE_INSTALL_PREFIX.

f3c7d22dd0 CMake: Don't use libraries in /usr/local by default on macOS
qmake builds of Qt don't use libraries in /usr/local because the
path is not considered a system path. Only the SDK path should be
used as a source of system libraries.

We should do the same for the CMake builds, which involves a couple of
things.

Tell CMake not to consider /usr/local (and a bunch of other
paths) as system prefix paths.

Disable pkg-config usage which by default is not used in qmake
Windows and macOS builds.

If a user wishes to use libraries located in /usr/local on macOS, they
can explicitly enable the behavior via -DFEATURE_pkg_config=ON.

In addition to enabling pkg-config, that will also disable the system
prefix modification described above.

Implementation notes

To disable pkg-config usage, we set an empty path for
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.

3ef14c8943 CMake: Fix framework handling for .pri files
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.

d7efb2a419 CMake: Fix include paths for AUTOMOC when using frameworks
The qml app was crashing when used by qtdeclarative auto tests. It
complained about unregistered QML types. qmltyperegistrar didn't
create registration info for these types. moc didn't output class info
about these types because the build system didn't provide the proper
include paths.

In qmake land, moc was given 2 sets of paths when building a module:
the non-installed framework dirs as -F flags, and also the
$repo_build_dir/include paths as regular -I flags.

In CMake land we only gave include paths to the non-installed
framework dirs as -I flags, not -F flags.
That's because AUTOMOC checks for a specific pattern in the include
paths to transform them into framework include paths
(existence of Foo.Framework/Headers symlink),
and we didn't pass such an include path.

Make sure to mimic what qmake does, and pass -I flags to
$repo_build_dir/include as public include paths, but only via
BUILD_INTERFACE aka when building Qt itself.

Also pass -F flags by specifying framework include paths in the
pattern that AUTOMOC expects.

06557312d2 CMake: Improve .prl dependency tracking
Previously .prl files were created via add_custom_command with a
POST_BUILD command. This means they were only created after linking
the libraries, and that whenever a relinking happened, dependees had
to rebuild many parts of their target.

Ideally we would use generator expressions in the OUTPUT argument, but
versions up-to CMake 3.18 don't support doing that.

A workaround is to create and depend on a .prl file name without
generator expressions, and as a side effect also create a .prl file
that does use generator expressions, but don't specify it as an
OUTPUT.

This seems to work well, and improves the dependency tracking issue,
at the cost of one more file copy per .prl file whenever it changes.

f626c73b28 CMake: Fix many failing qtdeclarative MinGW tests
A lot of qtdeclarative tests fail due to not finding the
QtTest qml plugin in ${prefix}/qml. This is just the symptom, the
problem is that the combination of CMake + MinGW + Qt relocatability
behaves incorrectly.

The value returned by
QLibraryInfo::location(QLibraryInfo::Qml2ImportsPath) for the
qmltestrunner executable is ${prefix}/bin/qml which is incorrect.

This happens due to a combination of things. The
c33916a279 change in qtbase introduced
checks to figure out whether an application is a windeployqt-ed app
to adjust the prefix path.

This check tries to find the import library libQt6Core.a in the lib
subfolder whenever the executed app dir path is equal to the
computed prefix path.

If it's found, the code assumes we are running a tool in
${prefix}/bin. If it's not found, the code assumes it's a
windeployqt'ed app, where the Qt .dlls are next to the executable.

Currently when QtCore is built with CMake targeting MinGW, we actually
create a libQt6Core.dll file instead of a Qt6Core.dll file, and also
an import library called libQt6Core.dll.a, instead of libQt6Core.a.

The prefix check code actually prepends an additional "lib", thus
trying to find the liblibQt6Core.a import library.

This fails, the code assumes a windeployqt'ed app, and returns the
currently executed app path dir as the prefix aka ${prefix}/bin in
the case of qmltestrunner, and thus none of the qml plugins are found.

To fix this, generated the shared library and the import library names
as qmake expects them, aka Qt6Core.dll and libQt6Core.a.

Some of this renaming was done for MinGW plugins and shared libraries,
but not for modules in 9b0e23ef8a.

Extract the duplicate code and apply it to all shared libraries built
by Qt on Windows. Adjust the prefix and suffix accordingly, depending
on whether we use MinGW or not.

58a7e4f0bc CMake: Implement workaround for failing linux static builds
In static builds, due to our CMake design for auto-linking plugins
being incorrect we sometimes cause link failures on Linux in leaf
modules, because the link line order is incorrect.

So far such failures were fixed by explicitly modifying the order of
libraries on the link line in each failing CMake project.

This proves to be problematic because the failures appear in seemingly
random integrations that don't even touch the build system parts.

Until we fix the design, another less performant but more
general / safe way is to increase the link interface multiplicity,
which causes a cycle of libraries to be repeated more than 2 times
on the link line, thus giving the ld linker more chances to figure out
which symbols are needed for linking.

Implement this for Linux static builds to avoid random integration
failures for people that know nothing about this issue.

The link multiplicity for all qt modules is increased to 3, thus
QtGui would be repeated 3 times on the link line of each dependent
library. The value is also configurable via the
QT_LINK_CYCLE_MULTIPLICITY cache variable.

1e1e6e288a CMake: Rename cpp compile check to HAVE_DASH_UNDEFINED_SYMBOLS
It used to be called HAVE_DASH_UNDEFINED_ERROR, but that always
cause Coin to print the compile check as the first build error snippet
because it contains the word "error", and whenever you get emails from
Gerrit the first snippet is always this compile check.

Rename it to avoid confusion in emails and Coin status reports.
