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.

CMake: Fix build of Release user projects against RelWithDebInfo Qt Building a user project in Release configuration against a Qt built with CMAKE_CONFIGURATION_TYPES=RelWithDebInfo;Debug led to the user project 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.

"Simplify" versionless targets Versionless targets in Qt6 are interface libraries that link the versioned libraries using the INTERFACE link type. This makes the linking chain more complicated than it can be. Also we miss some significant interface properties in the versionless targets comparing to the versioned targets. The new approach manually generates the versionless targets, instead of using CMake exports. For CMake versions < 3.18 we now create a copy of the versioned targets. The copy includes all the relevant INTERFACE properties from the versioned targets and imported locations for all configs. For CMake versions >= 3.18 we now create the versionless target ALIASes which should behave give the transparent access to the versioned targets. Using the QT_USE_OLD_VERSION_LESS_TARGETS flag you may force the behavor of the CMake versions <= 3.18 The change is partial workaround for QTBUG-86533.
