46cf1f11f0 Don't query MODULE_PLUGIN_TYPES property on interface libraries
The reason is that interface libraries have to have properties
prefixed with INTERFACE_ and more importantly we don't set the
property for interface libraries at the moment.

ffe0889413 Fix examples find_package calls to work in prefix builds
To build examples as part of a non-installed Qt prefix build,
not-yet-installed Config files need to be found by find_package()
calls inside example projects.

Facilitate that by propagating the CMAKE_PREFIX_PATH and
QT_EXAMPLES_CMAKE_PREFIX_PATH paths in all relevant find_package()
calls where NO_DEFAULT_PATH is used.

Also adjust the inclusion of the QtFeature.cmake file to be relative
to the qt6 directory, rather than the current list directory.
This is needed to successfully find the file when parsing a Config
file from a non-installed build directory.

1fc70ac0de Fix creation of generated plugin cpp files in static builds
When building qtdeclarative against a static iOS qtbase build,
QtNetwork is find_package'd twice, once in the top level
CMakeLists.txt file, and once by the qtuiotouchplugin which has
Network as a dependency.

This meant that the static plugins that Network exposes had
auto import cpp files generated twice, which failed the configuration
of qtdeclarative.

To fix this, don't generate the same file more than once.

To do that, protect the inclusion of the FooPlugins.cmake file, to
only be included once in every directory scope. That can be achieved
by setting a variable to TRUE when the target does not exist yet.

If the target exists in the same scope, that means that find_package()
was called a second time in the same scope, so there is no need
to include the Plugins file.

6732fa3a29 Fix linking of examples
Provide add_qt_gui_executable() as function in our public API that takes
care of automaticWinMain linkage. We can use this in the future to
encapsulate similarplatform-specific behavior and adjustments, such as
module generation onAndroid.

In order for the examples to see the function in Qt5CoreMacros, three more
additional fixes were required:

    * Do the build_repo_end() call _before_ attempting to build the
      examples, as we need the build_repo_end() to include QtPostProcess
      and complete the creation of all the target config files.
      Otherwise the find_package() calls in the examples see something
      incomplete.

    * Add more QT_NO_CREATE_TARGET guards

    * Always call find_dependency on the dependencies, regardless of the
      target creation mode. This way a find_package(Qt5 COMPONENTS
      Widgets) will still load Qt5CoreMacros.

e7d1ec61e3 Collect more known modules when considering private libraries in
extend_target.

In extend_target(Foo) we go over all the ModulePrivate dependencies
to assign them to FooPrivate. To do that we use the QT_KNOWN_MODULES
variable.
The problem is that the variable gets reset when we build a new
repository, so when we build qtdeclarative, QT_KNOWN_MODULES has no
entries for Core, Gui, etc, but only Qml, Quick, etc.
And yet QmlPrivate has to depend on CorePrivate.

Change the module Config.cmake files to append their target name
to a global variable called QT_ALL_MODULES_FOUND_VIA_FIND_PACKAGE.
The global variable gets populated every time find_package(QtFoo)
is called.

Use the union of QT_KNOWN_MODULES and
QT_ALL_MODULES_FOUND_VIA_FIND_PACKAGE when considering FooPrivate
libraries.

140b65e36f Propagate QT_CMAKE_EXPORT_NAMESPACE via QtCore package
QT_CMAKE_EXPORT_NAMESPACE is used by the Qt packages to make features
available to the consuming CMake project. The value was moved to the
BuildInternals Config file, but that's wrong because consuming
applications not including the BuildInternals component would fail
to use any other Qt package.

Move QT_CMAKE_EXPORT_NAMESPACE to be propagated with QtCore package
again.

9542e78525 Use the qt_build_repo() macros for building qtbase as well
To implement this, create a new Qt5BuildInternals package.

All child Qt modules like qtsvg should use
find_package(Qt5BuildInternals) or
find_package(Qt5 COMPONENTS BuildInternals) in the their
top level CMakeLists.txt.
This will make the qt_build_repo() macros available.

For qtbase we slightly cheat, and specify a CMAKE_PREFIX_PATH
pointing to the source folder that contains the BuildInternals
package.

For the other modules we actually use a configured and installed
package Config file.

This change moves variables that used to be written into the
QtCore Config file into the BuildInternals package. This way
things that are relevant only for building additional Qt modules
does not pollute the QtCore package.

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.

9b0b464e82 Write find_dependency() calls in Qt Module config files
This change introduces a new function called qt_find_package()
which can take an extra option called PROVIDED_TARGETS, which
associates targets with the package that defines those targets.
This is done by setting the INTERFACE_QT_PACKAGE_NAME and
INTERFACE_QT_PACKAGE_VERSION properties on the imported targets.

This information allows us to generate appropriate find_dependency()
calls in a module's Config file for third party libraries.

For example when an application links against QtCore, it should also
link against zlib and atomic libraries. In order to do that, the
library locations first have to be found by CMake. This is achieved by
embedding find_dependency(ZLIB) and find_dependency(Atomic) in
Qt5CoreDependencies.cmake which is included by Qt5CoreConfig.cmake.
The latter is picked up when an application project contains
find_package(Qt5Core), and thus all linking dependencies are resolved.

The information 'which package provides which targets' is contained
in the python json2cmake conversion script. The generated output of
the script contains qt_find_package() calls that represent that
information.

The Qt5CoreDependencies.cmake file and which which dependencies it
contains is generated at the QtPostProcess stop.

Note that for non-static Qt builds, we only need to propagate public
3rd party libraries. For static builds, we need all third party
libraries.

In order for the INTERFACE_QT_PACKAGE_NAME property to be read in any
scope, the targets on which the property is set, have to be GLOBAL.

Also for applications and other modules to find all required third
party libraries, we have to install all our custom Find modules, and
make sure they define INTERFACE IMPORTED libraries, and not just
IMPORTED libraries.
