078cd61751 Fix CMake moc scanner to look for new macro Q_NAMESPACE_EXPORT
f66c1db16c in qtbase introduced a new
macro that the moc scanner has to look for.

Set an explicit list of macros to look for in the
CMAKE_AUTOMOC_MACRO_NAMES property of every target that has AUTOMOC
enabled, otherwise CMake AUTOMOC won't run moc on files that contain
the new macro.

a5b78a3660 cmake: implement default qpa plugin behavior for static builds
This is done by adding a DEFAULT_IF argument to add_qt_plugin, which accepts
if-evaluated expressions.

e.g.

    add_qt_plugin(myplugin
	DEFAULT_IF ${foo} STREQUAL ${bar}
        ...
    )

so that this mechanism can be reused later if necessary.

12b73cba89 Split module_config.yaml
There are things that could be shared around all Qt submodules. In particular
compiler specific configuration should not be repeated over and over.
The new file can be included directly from all modules that uses QtBase.

In longer term one would have a separate repository for such instructions as
most of them are not QtBase specific.

8c60782124 Fix XCB feature detection
The xcb feature controls whether to build the xcb platform plugin. The
feature depends among other things on

    qt_find_package(XCB 1.9 PROVIDED_TARGETS XCB::XCB)

to succeed. This means at the moment setting XCB_FOUND to true, that's
what the condition checks.

Later on, in configure.cmake, we also check for other components in the
XCB package, for example:

    qt_find_package(XCB COMPONENTS XINPUT PROVIDED_TARGETS XCB::XINPUT)

If this component is not available, the xcb platform plugin has perhaps
reduce functionality, but it should be built and the feature should be
abled. However it isn't, because when that find_package call fails,
XCB_FOUND will be set to false. And that in turn will disable the
feature as the condition fails.

Therefore this patch changes the condition to check for the presence of
the XCB::XCB target instead.

1c4510cfc4 Fix build with multi-config VS code generator
We want our libraries to end up in the same bin directory, not inside the
Debug\ or Release\ sub-directories. Their distinct names avoid a clash.

For our tools such as moc, uic, etc. we need to place the release build into
the bin directory explicitly, as by default multi-config generators place
binaries into the Debug\ or Release\ sub-directory.

This is also needed as cmake's automoc itself expects moc to be in the
bin directory.

One effect of this is that with a multi-config build, it is always necessary
to perform a release build first, otherwise the debug build won't find moc/uic.

Always install - not installing doesn't make much sense.
Add information about developer-build.

06a552eab0 Port ICC specific instructions
Coin implicitly was exporting some variables if ICC was used.

This patch is just a first step to enable ICC in CI. To make
it really working one would need to fix the QtBase code and
enable ICC in qt5 repository.

4de70ce952 Avoid hardcoding the underlying build tool
Since 3.15, not only --build can call the low-level build tool,
--install can also be used to run the installation. There's also an
environment variable that can be used to control the backend at cmake
time, but that may only be useful later.

fe3bd212fc Merge remote-tracking branch 'origin/wip/qt6' into wip/cmake
This changes many different CMake places to mention Qt6 instead of
Qt5.

Note that some old qt5 cmake config files in corelib are probably not
needed anymore, but I still renamed and kept them for now.
