Pull request description:

  The currently used Qt 5.15 is approaching [EOL](https://www.qt.io/blog/qt-5.15-extended-support-for-subscription-license-holders) and will reach it before the Bitcoin Core v30 release. 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
  ![image](https://github.com/user-attachments/assets/e06f8685-aa79-49e7-9e61-4d54563f6d04)
  which will be fixed in follow-ups.

  ### 3. macOS

  `bitcoin-qt` now uses the [Metal](https://developer.apple.com/metal/) backend.

  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)

Bitcoin Core

Setup

Bitcoin Core is the original Bitcoin client and it builds the backbone of the network. It downloads and, by default, stores the entire history of Bitcoin transactions, which requires several hundred gigabytes or more of disk space. Depending on the speed of your computer and network connection, the synchronization process can take anywhere from a few hours to several days or more.

To download Bitcoin Core, visit bitcoincore.org.

Running

The following are some helpful notes on how to run Bitcoin Core on your native platform.

Unix

Unpack the files into a directory and run:

  • bin/bitcoin-qt (GUI) or
  • bin/bitcoind (headless)

Windows

Unpack the files into a directory, and then run bitcoin-qt.exe.

macOS

Drag Bitcoin Core to your applications folder, and then run Bitcoin Core.
