The recent migration of the build system to CMake makes it possible to switch to Qt 6. This PR updates the OS runtime compatibility requirements for the Bitcoin Core GUI as follows: ### 1. Linux Starting with Qt 6.5.0, the `libxcb-cursor0` package is required to be installed at runtime. ### 2. Windows Cross-compiling does not support LTO. We have to re-add it in a follow-up. A new style plugin causes minor visual glitches, such as  which will be fixed in follow-ups. ### 3. macOS `bitcoin-qt` now uses the [Metal](https://developer.apple.com/metal/) backend. --- **IMPORTANT.** Don't forget to install [Ninja](https://ninja-build.org/). --- For historical context, please refer to: - https://github.com/bitcoin/bitcoin/issues/20627 - https://github.com/bitcoin/bitcoin/pull/24798 --- UPD 2024-10-09. Qt 6.8 has been [released](https://www.qt.io/blog/qt-6.8-released), but it has some [drawbacks](https://github.com/bitcoin/bitcoin/pull/30997#issuecomment-2402990346) for us. As a result, this PR will stick to Qt 6.7. UPD 2025-03-18: [Standard support for Qt 5.15 will end after 26th of May 2025](https://www.qt.io/blog/extended-security-maintenance-for-qt-5.15-begins-may-2025) ACKs for top commit: laanwj: re-ACKf00345727bhodlinator: re-ACKf00345727bTree-SHA512: 367f722e6c3ea4700b5395871c40b6df8c8062fdc822107090449ea4ae4ad2db75cc53a982a678f4c48ce8f9b2d43ed10e6d23b06165ab78713f161db712d895

Additional tools, including the github-merge.py script, are available in the maintainer-tools repository.
Verify-Commits
Tool to verify that every merge commit was signed by a developer using the github-merge.py script.
Linearize
Construct a linear, no-fork, best version of the blockchain.
