Add license headers to cmake files CMakeLists.txt and .cmake files of significant size (more than 2 lines according to our check in tst_license.pl) now have the copyright and license header. Existing copyright statements remain intact Task-number: QTBUG-88621 Change-Id: I3b98cdc55ead806ec81ce09af9271f9b95af97fa Reviewed-by: Jörg Bornemann <joerg.bornemann@qt.io> 2022-07-05 11:26:52 +00:00			`# Copyright (C) 2022 The Qt Company Ltd.`

Check whether CMake was built with zstd support CMake 3.18 introduced the file(ARCHIVE_CREATE) API that we use with COMPRESSION Zstd for compressing corelib's mimedatabase. It's possible to build CMake without proper zstd support, and we have encountered such builds in the wild where the file(ARCHIVE_CREATE) call crashes. Add a configure test to determine whether CMake properly supports the Zstd compression method.
