c4856a9075 Use QScopedPointer to manage memory
Although the QBackingStore constructor takes a QWindow* as a parameter,
it does not inherit QObject and doesn't become a QObject child of the
QWindow. Use QScopedPointer to avoid memory leaks.

d97fd7af2b Build examples in isolated sub-builds using ExternalProject
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.

efa9998521 Fix compiling of examples on Android
* 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.

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.

9c17b8adb9 Update rasterwindow example to not render in resizeEvent
The resize event should not be used to draw, as there will be a follow-up
exposeEvent delivered just after, and we don't want to draw twice.

This is how QRasterWindow operates too, except it defers the backingstore
resize to beginPaint() instead of resizing in the reizeEvent.

It's also how QOpenGLWindow operates, which also has a note for the
virtual resizeGL method saying: "Scheduling updates from here is not
necessary. The windowing systems will send expose events that trigger
an update automatically."

3b0c2b7c1b Examples: Add Q_DECL_OVERRIDE to overridden functions
Q_DECL_OVERRIDE (which expands to 'override' for supported compiler)
helps to declare the intent (that it is an overridden function) and
force compilation error when there is no such virtual function in the

The examples should show the best practice of having it, as it may save
the programmer quite some time in case of change of API or typo in the
function name or arguments.

This change was done automatically with
clang-modernize -add-override -override-macros
