f65abc6344 CMake: Export QT_QPA_DEFAULT_PLATFORM in QtBuildInternalsExtra
The value is useful for QPA plugins built in repos other than qtbase,
to decide if it should be a default plugin or not.
Currently useful for qtwayland.

Also export a qmake value assignment when doing static builds, just
like src/gui/configure.pri does.

bcc7d34540 CMake: Provide a qt-internal-configure-tests script
This is meant to be called by our CI instructions to build standalone
tests of a Qt repository.

Currently it just calls qt-cmake with
-DQT_BUILD_STANDALONE_TESTS=ON, but it might contain more things in
the future.

The script also simplifies configuring standalone tests locally, due
to not having to remember the name of the magical variable.

Change our CI instructions to use the new script.

1b4ea4a1d8 CMake: Fix target dependency cycle regarding qpa plugins in qtwayland
With the introduction of the new 'default_qpa_plugins' custom target,
a target dependency cycle occurred in qtwayland:
qtwaylandscanner -> default_qpa_plugins -> a wayland qpa plugin ->
WaylandClient -> qtwaylandscanner

The issue is twofold:
- default_qpa_plugins accidentally depended on non-qpa plugins.
- All qpa plugins were enabled by default, including the wayland ones.

Fix the default_qpa_plugins target not to depend on regular non-qpa
plugins.

Also fix qpa plugins not to be enabled by default, but instead only
choose one qpa plugin to be the default (via evaluating the
DEFAULT_IF) condition.

5fa823491b CMake: Fix automatic sysrootification detection for qmake
The way we detected whether SysrootifyPrefix needs to be set was
incorrect.

We checked if extprefix == prefix => SysrootifyPrefix should be
true. But that was previously always the case for a non-prefix build,
which means it was not possible to build apps (due to qmake expecting
to find include dirs in the sysroot, despite the non-prefix Qt not
being installed anywhere into the sysroot).

Instead we should do what qmake does. Only set SysrootifyPrefix to
true if extprefix was not provided and a sysroot is available.

To make it work for iOS and Android, the sysroot detection code had to
be moved earlier than the SysrootifyPrefix detection.

4bf8f70bfe CMake: Let doc targets depend on doc tools in top-level build
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 targets. Thus, we must defer the dependency connection if
the doc tool target is not yet available.

This patch adds the functions qt_internal_defer_dependency and
qt_internal_add_deferred_dependencies.

7c23281db3 CMake: Fix headersclean to work on macOS
It appears there's a difference between the chosen macOS compiler path
in the CI versus the compiler path on my local machine.

In the CI the chosen compiler path ends up 'being /usr/bin/clang++'
whereas for me locally it's

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/c++

For some reason the headersclean commands succeed in the CI, but
locally they fail for me saying that standard library includes can not
be found, unless an explicit sysroot flag is specified.

I assume that in the CI the '/usr/bin/clang++' compiler shim chooses some
implcit sysroot, whereas the longer Xcode compiler expects an explicit
sysroot.
It's probably also affected by the fact that in the CI we pass an
explicit CMAKE_OSX_SYSROOT to a non-standard Xcode location e.g.

/Applications/Xcode11.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.15.sdk

Note the '11' in the Xcode app name.

Locally I don't pass a custom CMAKE_OSX_SYSROOT, and my Xcode is
installed in a regular location e.g /Applications/Xcode.app.

The sysroot flag and path is added to regular CXX compilation rules
inside CMake's core (in cmLocalGenerator.cxx).

Reuse the same variables that CMake uses and add them to our headersclean
command rules.

80a2878e20 CMake: Fix additional target info files
...for QT_BUILD_TOOLS_WHEN_CROSSCOMPILING.

qt_internal_export_additional_targets_file now gets two lists of target
names when run from qt_export_tools:
 - TARGETS containing actually existing targets, and
 - TARGET_EXPORT_NAMES containing the target names as they appear in the
   additional target info file.

Operations that require actual targets are run on the TARGETS, in the
additional target info file only TARGET_EXPORT_NAMES are written.

This distinction is required for the case where the host Qt lacks a
tool that is built in the target Qt.

Example: host Qt is built with DEVELOPER_BUILD=OFF, target Qt is built
with DEVELOPER_BUILD=ON. Then the host Qt lacks qmljs, but it is built
in the target Qt. TARGETS contains qmljs_native, and
TARGET_EXPORT_NAMES contains qmljs.

It appears that CMake's Xcode generator default behavior can't really
handle imported object libraries location, which Qt uses extensively
(all the qt_add_resource calls).

Specifically the project fails to configure with the following error
message:
The OBJECT library type may not be used for IMPORTED libraries under
Xcode with multiple architectures.

An issue was filed upstream at
https://gitlab.kitware.com/cmake/cmake/-/issues/21276

In the mean time, it looks like it's possible to work around the issue
by setting XCODE_EMIT_EFFECTIVE_PLATFORM_NAME global property to OFF.
This needs to be done before the very first project() call, so we do
it in the generated Qt toolchain file.

Note that the workaround only works if the CMake project is configured
with a single architecture given to CMAKE_OSX_ARCHITECTURES.
If multiple arches are given, it will fail with the same error
message.

28ed9e3e2d CMake: Set some additional info variables in Qt6CoreConfigExtras
Add info whether Qt was an infix built, and whether the reduce_exports
feature was enabled. These variable were set before in
Qt5CoreConfigExtras.cmake.

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.

22b72a6f7a win: Set correct target mkspec for qmake builds for arm64 builds
As there is no other way of obtaining information about Qt's paths at the
moment, windeployqt is still querying qmake for these information. For a
cross compiled Qt, the proper target mkspec has to be set in this case.

ab4acdbeb1 Do not build tests and examples by default for configure -cmake
Tests were never built by default, except for -developer-build.
Examples were build, but aren't anymore by default if you
run cmake directly.

Let the default be figured out by cmake, and only set
BUILD_EXAMPLES and BUILD_TESTING if the user has
expicitly passed them via -make or -nomake.
