Conan: Read status flag from .cmake.conf The status information (alpha1, beta2, rc3, ...) needs to be part of the Conan package reference. As Conan supports semantic versioning the best place to put the status is to append it to the version string: qtbase/6.2.0-alpha1@qt/everywhere qtbase/6.2.0-beta2@qt/everywhere qtbase/6.2.0-rc3@qt/everywhere qtbase/6.2.0@qt/everywhere Other Conan packages declaring a dependency can use e.g. syntax: # notice the asterix character after version self.requires(f"qtbase/[<=<version>, include_prerelease=True}]@..) This way the status information is not in the Conan channel part and downstream consumers of the Conan package does not need to update the dependency (Conan reference string) every time the version changes. Put the status information next to Qt version string in .cmake.cache.

CMake: Enable NEW policies by CMake version with a global default 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.

# Minimum requirement for building Qt
CMake: Enforce minimum CMake version in user projects This change introduces new behavior to error out when configuring user projects if the CMake version used is too old for Qt to work with. The main motivator is the requirement of new CMake features to ensure object libraries are placed in the proper place on the link line in static builds. The minimum CMake version is computed based on whether Qt was configured as shared or static libraries. At the moment the required versions for building and using Qt are the same. The minimum versions are defined in qtbase/.cmake.conf in the following variables QT_SUPPORTED_MIN_CMAKE_VERSION_FOR_BUILDING_QT_SHARED QT_SUPPORTED_MIN_CMAKE_VERSION_FOR_BUILDING_QT_STATIC QT_SUPPORTED_MIN_CMAKE_VERSION_FOR_USING_QT_SHARED QT_SUPPORTED_MIN_CMAKE_VERSION_FOR_USING_QT_STATIC Qt Packagers can disable the version check when configuring Qt by setting QT_FORCE_MIN_CMAKE_VERSION_FOR_BUILDING_QT and QT_FORCE_MIN_CMAKE_VERSION_FOR_USING_QT. In this case it is the packagers responsibility to ensure such a Qt works correctly with the specified CMake version. User projects can also set QT_FORCE_MIN_CMAKE_VERSION_FOR_USING_QT to disable the version check. Then it's the project's developer responsibility to ensure such a Qt works correctly. No official support is provided for these cases. Implementation notes. The versions required to build Qt are stored in QtBuildInternalsExtra.cmake whereas the versions required to use Qt are stored in a new QtConfigExtras.cmake. Also the policy range variables stored in QtBuildInternalsExtra.cmake are now regular variables instead of cache variables, to properly allow overrides per-repository. Some renaming of functions and variables was done for a bit more clarity and easier grep-ability.

# Policy settings for commands defined by qtbase. These will also be injected
# into the top level policy scope of each Qt module when building Qt so that
# modules have the same policy settings as qtbase by default. They can be
# overridden by individual Qt modules in their own .cmake.conf files if needed.
#
# NOTE: These two values are also hard-coded in QtBuildInternalsConfig.cmake
# because that file is used in-place by a superbuild, so there is no
# opportunity for substituting the values from here. Keep both locations
# in sync.
CMake: Bump min required CMake version for shared Qt builds to 3.16 Building a shared library Qt configuration already required a minimum CMake version of 3.16, because we depend on CMake's Autogen.json files which are used for metatype.json file generation. If a lower version was used, a FATAL_ERROR was issued in qt6_extract_metatypes. This change is essentially moving the check to happen earlier in the qtbase configure process. User projects will now /also/ officially require a minimum of 3.16 (up from 3.14). As a consequence, the min/max version policy range that is set in the public QtFooConfig.cmake files is changed from 3.14..3.19 to 3.16..3.20 The upper bound is raised because building and using Qt works fine with all CMake 3.20 policies set to NEW.
