Examples are intended to show how to build against an installed Qt.
Building them as part of the main build means the way the Qt targets
are defined and created are not representative of an end user's build.
By building them as separate projects using ExternalProject, we can
more closely replicate the intended audience's environment. This
should allow us to catch more problems earlier.
Having examples built as part of the main build also creates problems
with some static builds where a tool built by the main build is needed
during configure time. This happens with other repos like qtdeclarative
but not (currently) with qtbase. Converting the examples in qtbase to
be built using ExternalProject is intended as a demonstrator for how
other repos can do similar. Until other repos are converted, they will
continue to work as they did before, with examples as part of the main
build for non-static builds only.
The new build-externally behavior is only supported for non-prefix
builds with this change. Prefix builds will continue to use the old
non-external method. Support for building examples externally in
prefix builds will be a separate change.

This gives some source incompatibilities, most of them can be
handled by using auto instead of QStringRef explicitly.
[ChangeLog][Important API changes] QXmlStream now uses QStringView
insteead of QStringRef in it's API. Using auto forvariables returning
a QStringRef in Qt 5 should lead to code that can be used against both

* Simplify add_qt_gui_executable() to not require WIN32/MACOSX_BUNDLE
but provide it implicitly. It's redundant :)
* When on Android, build a module (shared library), just like qmake.
This requires an additional library destination in the install() call,
but that's ignored on other platforms.
* Fix typos in the android deployment generation settings function
* Use the correct cache variable to determine whether we're inside a Qt
build or not. Right now this only works inside Qt builds anyway as
QtPlatformAndroid.cmake is not publically accessible.

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.

functions, prefer calling these functions over doing arithmetic with
M_PI (or approximations thereto) and 180 (give or take simple

name of the function used (and reveals at least one place where
variables were misnamed; the return from atan is in radians, *not*
