To be able to link a Release user project against a RelWithDebInfo Qt we
set several IMPORTED_*_RELEASE properties in
the *AdditionalTargetInfo.cmake file of each Qt module.
The EntryPoint module however is a bit special as it is an
INTERFACE_LIBRARY linking publicly against a static
library (EntryPointimplementation). Its *AdditionalTargetInfo.cmake file
was almost empty, because qt_internal_export_additional_targets_file was
called before EntryPointImplementation was set up. Also,
qt_internal_add_module, which calls
qt_internal_export_additional_targets_file, does not know that we want
to export the EntryPointImplementation target.
We fix this by telling qt_internal_add_module(EntryPoint) to not
generate the *AdditionalTargetInfo.cmake file and call
qt_internal_export_additional_targets_file later to take the targets
EntryPoint and EntryPointImplementation into consideration.
qt_internal_add_module learned the option NO_ADDITIONAL_TARGET_INFO to
turn off the generation of *AdditionalTargetInfo.cmake files.

When a CMake release introduces a new policy that affects most Qt
modules, it may be appropriate to make each module aware of that newer
CMake version and use the NEW policy without raising the minimum CMake
version requirement. To reduce the churn associated with making that
change across all Qt modules individually, this change allows it to be
updated in a central place (qtbase), but in a way that allows a Qt
module to override it in its own .cmake.conf file if required (e.g. to
address the issues identified by policy warnings at a later time). The
policies are modified at the start of the call to
qt_build_repo_begin().
For commands defined by the qtbase module, qtbase needs to be in
control of the policy settings at the point where those commands are
defined. The above mechanism should not affect the policy settings for
these commands, so the various *Config.cmake.in files must not specify
policy ranges in a way that a Qt module's .cmake.conf file could
influence.
Starting with CMake 3.12, policies can be specified as a version range
with the cmake_minimum_required() and cmake_policy() commands. All
policies introduced in CMake versions up to the upper limit of that
range will be set to NEW. The actual version of CMake being used only
has to be at least the lower limit of the specified version range.
This change uses cmake_minimum_required() rather than cmake_policy()
due to the latter not halting further processing upon failure.

The QT.<module>.DEFINES assignment in pri files needs to take into
account the module name when computing the define name. This is the
MODULE value that qmake specifies.
In CMake that would be the value of CONFIG_MODULE_NAME.
Previously the value of the define was computed in
qt_internal_module_info() without taking into account the module name.
While qt_internal_module_info() ended being used also for plugins and
other target types, the defines computed by it were meant to be used
only for Qt modules.
Thus remove the <result>_define assignment from
qt_internal_module_info and move its computation directly into
qt_internal_add_module, taking into account the value of
CONFIG_MODULE_NAME.
The only other use of module_define was in qt_internal_add_plugin but
that was merely a long overdue copy-paste error, qmake doesn't
propagate QT_FOO_LIB defines for plugins.
As result, a define special case in testlib is not needed anymore,
because the define is now computed properly.
Finally, QT_FOO_LIB should not be used while building the Qt module
itself, so instead of using PUBLIC_DEFINES option of
qt_internal_extend_target, use target_compile_definitions(INTERFACE)
directly.

Building a user project in Release configuration against a Qt built with

being linked against the Debug Qt libraries. This is especially painful
with MSVC where debug and release runtimes are incompatible.
We now create *AdditionalTargetInfo.cmake files along the
exported *Targets.cmake files that set the IMPORT_*_<CONFIG> properties
to the values of the release config Qt was built with.
User projects built with an unknown
configuration (CMAKE_BUILD_TYPE=ArbitraryName) will link against a
release Qt. This can be controlled by setting the variable
QT_DEFAULT_IMPORT_CONFIGURATION to, for example, DEBUG in the user
project.

Configure Qt with -DQT_FEATURE_headersclean=ON to enable the

when the module is built for the first time.
There are notable differences to the qmake version:
- the build does not pick up anymore default defines or flags from
the module, or Qt. Instead options like -fPIC they have to be listed
explicitly. Also for this reason, we have to skip the vulkan-related
headers from the check, since vulkan/vulkan.h is not necessarily
in the compiler's default search path.
- some checks for nowadays unsupported compiler versions are
removed.
- -Wdouble-promotion -Wshorten-64-to-32 is not added for clang
builds; the qmake code path did never enforce that on CI
machines (it was non-Apple clang only), and the check currently
fails on these configurations.
