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.

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

Apparently calling set_package_properties with TYPE REQUIRED and
then calling feature_summary with FATAL_ON_MISSING_REQUIRED_PACKAGES
and PACKAGES_NOT_FOUND is not enough to make CMake fail when not
finding a required package.
You have to explicitly set REQUIRED_PACKAGES_NOT_FOUND to force
feature_summary to fail when a package is not found.
Do this, and also explicitly add the rest of the NOT FOUND cases,
to get a slightly clearer overview what kind of packages were not
found.

We must instruct cmake that we're interested in providing input files
for the assembler directly and the file name needs to be correct, too :)

It appears that the latest cmake provides 3.14 as a proper version.

* Only import features once
* Move Core specific code into its CMakeLists.txt file
* More consistently use target names like "Core" to
refer to "Qt modules". We tend to require either "Core"
or "QtCore" in places, which I find confusing.
