fb656c036d Remove .qmake.conf from this repository
This file was necessary for the qmake build and the CI.  The qmake
build is history, and the CI does now read .cmake.conf (see
QTQAINFRA-4392).

In addition to being superfluous, the existence of .qmake.conf
triggers QTBUG-76140 when building Qt examples with qmake.  Removing
the file alleviates the symptoms of this bug.

"Interestingly", to make the qmake build of examples work in the CI, we
have to adjust the dbus examples to not use nmake inference rules.  The
absence of .qmake.conf results in a different order of inference rules
in the Makefile, and nmake/jom pick up generated source files from the
source dir.  These are incompatible with the correct generated source
files in the build dir.  See QTBUG-96513 for details.

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.

b71c04353d CMake: Work around building dbus 'controller' example with qmake
Similar to what has been done in 5138a970f3, we need to adjust the
remotecontrolledcar/controller dbus example to be built with qmake.

In the CI we first build the examples with CMake in the source
directory. That creates some generated source files in the dbus example
dir.

Then, the examples are (will be) built ouf of source with qmake, and
those generated source files will be placed in the build directory.

When building with MSVC, there's a peculiarity with nmake/jom's
inference rules that lead to picking up the generated car_interface.cpp
from the source directory, instead of the build directory.
See QTBUG-13496 for details.

car_interface.cpp, built with CMake is generated to include
car_interface.moc.
car_interface.cpp, built with qmake does not have this include, but the
build system calls moc on car_interface.h.

All this leads to duplication of the meta object for
OrgExampleExamplesCarInterfaceInterface, preventing successful linking.

Work around this issue by turning off the generation of nmake/jom
inference rules.

5138a970f3 CMake: Workaround building DBus 'car' example with qmake
While trying to implement instructions for building examples with
qmake in the CI, an issue has surfaced.

When building examples with CMake with -DBUILD_EXAMPLES=ON in the CI,
the examples are built in-source, aka source dir == build dir.
This means that the header files generated by qdbusxml2cpp will be
placed in the qtbase source dir.

The instructions that try to build examples with qmake build the
examples in a separate build dir after building the examples with CMake.

Unfortunately the qtbase/examples/dbus/remotecontrolledcar/car example
includes the generated DBus adaptor header via a statement like
  #include "car_adaptor.h"
and the compiler prefers to pick up the header file from the example
source dir (the one generated by CMake), rather than the one generated
by qmake in the example build dir.

Because CMake's DBus integration uses different flags than qmake's
DBus integration, the generated header file code is not compatible
with the qmake generated cpp file, and the example fails to link when
building with qmake, because it can't find an appropriate constructor
symbol.

In an ideal world, we wouldn't do in-source builds with the CMake
build, but that leads to other issues which I currently don't recall.

To circumvent the issue, adapt the CMake DBus qt6_add_dbus_adaptor
function to allow not passing the problematic '-l' flag by making it
optional. This shouldn't break existing code, but allows us to
generate a compatible header that will be used by qmake and succeed in
linking the example.

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.

99539a2894 Allow to build examples as standalone project
Create CMake config files which can be used from the very same CMake
project. These CMake config files simply do not create any targets,
controlled via the QT_NO_CREATE_TARGETS.

This patch also allows to build qtbase.git:examples as a standalone
project, against an already-built Qt.

Ran this:
  ag -s "QT " examples -l -0 | xargs -0 -n 1 .../util/cmake/pro2cmake.py --is-example
