pro2cmake.py: Generate .cmake.conf files for versioning And create one for QtBase at the same time. Fixes: QTBUG-83835 Change-Id: Icc6b022165a57bd4e22c23bdb0016522b99a5b80 Reviewed-by: Alexandru Croitor <alexandru.croitor@qt.io> 2020-04-28 15:46:21 +00:00			`set(QT_REPO_MODULE_VERSION "6.0.0")`
CMake: Bump the minimum required CMake version to build Qt to 3.18 Add a new function that returns the minimum CMake version required to build Qt. Pass that value to cmake_minimum_required() when building qtbase and its standalone tests. The minimum supported CMake version is read from qtbase/.cmake.conf and its value should be updated when the need arises. It's the main source of truth for all repos. Provide a way to lower the minimum CMake version at configure time by passing a value via QT_FORCE_MIN_CMAKE_VERSION. This is not an officially supported way of building Qt. If the specified version is lower than Qt's supported minimum, show a warning. Nevertheless the option is useful for testing how Qt builds with a different minimum CMake version due to different policies being enabled by default. Issue warnings for CMake versions that are higher than the minimum version but are known to cause issues when building Qt. A counterpart change is needed in qt5 to ensure the minimum CMake version is set at the proper time for top-level builds. Ideally we would use the same 'check the CMake minimum version` code in all our repositories, but that will cause lots of duplication because we can't really find_package() the code and doing something like include(../qtbase/foo.cmake) hardcodes assumptions about repo locations. So for now we don't bump the minimum version in child repo cmake_minimum_required calls (qtsvg, qtdeclarative, etc). Instead we record both the minimum supported version and the computed minimum version (in case a different version was forced) in QtBuildInternalsExtra.cmake. Then we require qtbase's computed min version in qt_build_repo_begin(). This won't set policies as cmake_minimum_required would, but at least it propagates what minimum CMake version should be used for child repos. We might still have to bump the versions in child repos at some point.
