a39a0e5419 Fix build of modules outside of QtBase when cross-compiling
The Qt::Platform target includes the mkspecs/$spec directory, which we
must unconditionally install as long as we use it.

fe3bd212fc Merge remote-tracking branch 'origin/wip/qt6' into wip/cmake
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.

72066a3a58 Revert "cmake: Make CMake superbuilds work"
Builds fail on Windows, due to splitting on ':' on absolute file paths,
when handling syncqt injections.

Revert for now to get qt6 merge in faster.

This reverts commit 7559d508d1.

7559d508d1 cmake: Make CMake superbuilds work
In case of a CMake superbuild, the actual install root in a non-prefix
build is the top-level build directory (not $TOP_BUILDDIR/qtbase anymore).
This is more in line how CMake lays out things by default.

c7fd10a022 Allow building the tests directory as a standalone CMake project
At the moment, Coin builds tests as a separate qmake invocation
against an installed Qt. We need to support the same with CMake.

Change the tests subdirectory to be a standalone CMake project when
CMake does not detect an existing QtTest target while processing the
subdirectory. If the target exists, it means we are building the whole
repo, if the target does not exist, we need to call find_package
to find the installed Qt.

Refactor and move around a few things to make standalone tests build
successfully:
- add a new macro to set up paths to find QtSetup
- add a new macro to find all macOS frameworks
- add a new macro to set up building tests
- add a new macro that actually builds the tests
- export the INSTALL_CMAKE_NAMESPACE value into the BuildInternals
  Config file
- export the CMAKE_BUILD_TYPE value, because a test project doesn't
  have a .git subdir and thus defaults to be built in Release
  mode, even though qtbase might have been built in Debug, so to
  avoid the mixing, the propagate the build type
- stop overriding INSTALL_CMAKE_NAMESPACE and
  QT_CMAKE_EXPORT_NAMESPACE inside QtSetup if they are set, because
  the tests project doesn't specify a major version, and if we
  override the values, the moc / uic targets don't get the correct
  major version prefix and configuration fails

02a015375a Implement developer / non-prefix builds
A non-prefix build is a build where you don't have to run
make install.

To do a non-prefix build, pass -DFEATURE_developer_build=ON when
invoking CMake on qtbase. Note that this of course also enables
developer build features (private tests, etc).

When doing a non-prefix build, the CMAKE_INSTALL_PREFIX cache variable
will point to the qtbase build directory.

Tests can be run without installing Qt (QPA plugins are picked up from
the build dir).

This patch stops installation of any files by forcing the
make "install" target be a no-op.

When invoking cmake on the qtsvg module (or any other module),
the CMAKE_INSTALL_PREFIX variable should be set to the qtbase build
directory.

The developer-build feature is propagated via the QtCore Config file,
so that when building other modules, you don't have to specify it
on the command line again.

As a result of the change, all libraries, plugins, tools, include dirs,
CMake Config files, CMake Targets files, Macro files, etc,
will be placed in the qtbase build directory, mimicking the file layout
of an installed Qt file layout.

Only examples and tests are kept in the separate module build
directories, which is equivalent to how qmake does it.

The following global variables contain paths for the
appropriate prefix or non prefix builds:
QT_BUILD_DIR, QT_INSTALL_DIR, QT_CONFIG_BUILD_DIR,
QT_CONFIG_INSTALL_DIR. These should be used by developers
when deciding where files should be placed.

All usages of install() are replaced by qt_install(), which has some
additional logic on how to handle associationg of CMake targets to
export names.

When installing files, some consideration should be taken if
qt_copy_or_install() needs to be used instead of qt_install(),
which takes care of copying files from the source dir to the build dir
when doing non-prefix builds.

Tested with qtbase and qtsvg, developer builds, non-developer builds
and static developer builds on Windows, Linux and macOS.

42d3b21c92 Export tool config and target files for each relevant module
CMake will now generate config and target files for each module that
provides tools. As a result, namespaced global targets such as
Qt5::moc or Qt5::rcc can be made available.

Third party projects that require just these tools, and not the Qt
modules themselves,  should specify CMAKE_PREFIX_PATH pointing to the
installed Qt location, and call find_package(Qt5CoreTools),
find_package(Qt5GuiTools), etc.

It is also possible to call
find_package(Qt5Tools REQUIRED Core Widgets) where the last option
is a list of modules whose tools should be imported.

Note that all the tools are in the Qt5::
namespace and not in the Qt5CoreTools:: or Qt5WidgetsTools::
namespace.

This commit also changes the behavior regarding when to build tools
while building Qt itself.

When cross compiling Qt (checked via CMAKE_CROSSCOMPILING) or when
-DQT_FORCE_FIND_TOOLS=TRUE is passed, tools added by add_qt_tool will
always be searched for and not built.
In this case the user has to specify the CMake variable QT_HOST_PATH
pointing to an installed host Qt location.

When not cross compiling, tools added by add_qt_tool are built from
source.

When building leaf modules (like qtsvg) that require some tool that was
built in qtbase (like moc), the module project should contain a
find_package(Qt5ToolsCore) call and specify an appropriate
CMAKE_PREFIX_PATH so that the tool package is found.

Note that because HOST_QT_TOOLS_DIRECTORY was replaced by QT_HOST_PATH,
the ensure syncqt code was changed to make it work properly with
both qtbase and qtsvg.

Here's a list of tools and their module associations:
qmake, moc, rcc, tracegen, qfloat16-tables, qlalr  -> CoreTools
qvkgen -> GuiTools
uic -> WidgetTools
dbus related tools -> DBusTools

a1752276e0 CMake: Do not link qmake against Qt (not even the bootstrap one)
Qmake should not rebuild all the code in QtCore, but currently it does.
When linking against QtCore, all the symbols get duplicated. A clever
linker will "deduplicate" the symbols again, so this actually works
with shared Qt builds, but it fails for static builds.

Do not rely on the linker being clever and just do not link Qt at all
for qmake.

- Fix vulkan headers to be found
- Fix freetype bzip and png unresolved symbols / linker issues
  when building minimal platform plugin (also need to make
  sure to use the vcpkg toolchain instead of CMAKE_PREFIX_PATH
  because then find_package is overridden, which does magic
  to properly propagate static library dependencies).
- Fix qfilesystementry test not to be built without private
  tests feature (it led to undefined symbols issues).
- Make sure to remove QT_NO_CAST_TO_ASCII define when building
  QtCore, so that the qstringbuilder3 test builds
  successfully.
