Before this patch we enabled AUTOMOC, AUTORCC, AUTOUIC for all targets
that did not opt out.
Aside from being wasteful from a performance point of view,
this also caused issues when trying to build qtimageformats which
does not depend on Widgets which is the package that exposes uic.
To avoid this, enable only AUTOMOC for all targets by default, and
UIC and RCC can be opted in via the ENABLE_AUTOGEN_TOOLS option.
To facilitate this some refactoring had to be done, like moving some
common setup for all autogen tools into a separate call, and making
sure that extend_target understands the autogen options, because some
ui files are only added conditionally.
Also the conversion script has been adapted to output the
ENABLE_AUTOGEN_TOOLS option whenever a .pro file contains at least
one FORMS += foo assignment.
Note that we don't really use AUTORCC while building Qt, so nothing
opts into that at the moment.

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

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

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.

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.

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
