ML announcement: https://groups.google.com/g/bitcoindev/c/hgKkfQWzrTo As discussed during the recent CoreDev meetup in April, the switch from Autotools to CMake is intended to happen as soon as possible after branching 28.x off, which means that 29.0 will be built using CMake. This PR branch is essentially the [staging branch](https://github.com/hebasto/bitcoin/tree/cmake-staging), with every change reviewed and tested by a group of contributors, including (in alphabetical order): - [**achow101**](https://github.com/achow101) - [**fanquake**](https://github.com/fanquake) - [**maflcko**](https://github.com/maflcko) - [**m3dwards**](https://github.com/m3dwards) - [**pablomartin4btc**](https://github.com/pablomartin4btc) - [**real-or-random**](https://github.com/real-or-random) - [**ryanofsky**](https://github.com/ryanofsky) - [**sipsorcery**](https://github.com/sipsorcery) - [**TheCharlatan**](https://github.com/TheCharlatan) - [**theStack**](https://github.com/theStack) - [**theuni**](https://github.com/theuni) - [**vasild**](https://github.com/vasild) Reviewing in a separate staging repo was suggested in https://github.com/bitcoin/bitcoin/pull/27060#issuecomment-1431798320. The accompanying changes to the OSS-Fuzz project are available in https://github.com/hebasto/oss-fuzz/pull/8. Please refer to the [build options parity table](https://gist.github.com/hebasto/2ef97d3a726bfce08ded9df07f7dab5e). The "auto" value is no longer available; non-default values must be specified explicitly. Additionally, the new default values have been chosen to suit the everyday build experience for the majority of developers. System requirements for using the CMake-based build system: - CMake >= 3.22 (if not available in your system's repository, it can be downloaded from https://cmake.org/download/) - a build tool of your choice: - any Make (GNU Make is no longer a requirement); GNU Make is still required to build depends - Ninja (https://ninja-build.org/) - MSBuild - Xcode A note for Windows users: The default installation of the latest version of MSVC 17.10.4 includes both CMake 3.28.3 and the vcpkg package manager). --- We, the build system developers, kindly ask reviewers to refrain from making suggestions that are not directly related to the migration process or can be implemented separately. Bugs in the scripts and errors in the updated documentation should be the focus of this PR. Please be advised that comments not aligned with this PR's goal may be ignored. Thank you all for your understanding.

CI Scripts
This directory contains scripts for each build step in each build stage.
Running a Stage Locally
Be aware that the tests will be built and run in-place, so please run at your own risk. If the repository is not a fresh git clone, you might have to clean files from previous builds or test runs first.
The ci needs to perform various sysadmin tasks such as installing packages or writing to the user's home directory. While it should be fine to run the ci system locally on you development box, the ci scripts can generally be assumed to have received less review and testing compared to other parts of the codebase. If you want to keep the work tree clean, you might want to run the ci system in a virtual machine with a Linux operating system of your choice.
To allow for a wide range of tested environments, but also ensure reproducibility to some extent, the test stage
requires bash, docker, and python3 to be installed. To run on different architectures than the host qemu is also required. To install all requirements on Ubuntu, run
sudo apt install bash docker.io python3 qemu-user-static
It is recommended to run the ci system in a clean env. To run the test stage with a specific configuration,
env -i HOME="$HOME" PATH="$PATH" USER="$USER" bash -c 'FILE_ENV="./ci/test/00_setup_env_arm.sh" ./ci/test_run_all.sh'
Configurations
The test files (FILE_ENV) are constructed to test a wide range of
configurations, rather than a single pass/fail. This helps to catch build
failures and logic errors that present on platforms other than the ones the
author has tested.
Some builders use the dependency-generator in ./depends, rather than using
the system package manager to install build dependencies. This guarantees that
the tester is using the same versions as the release builds, which also use
./depends.
It is also possible to force a specific configuration without modifying the file. For example,
env -i HOME="$HOME" PATH="$PATH" USER="$USER" bash -c 'MAKEJOBS="-j1" FILE_ENV="./ci/test/00_setup_env_arm.sh" ./ci/test_run_all.sh'
The files starting with 0n (n greater than 0) are the scripts that are run
in order.
Cache
In order to avoid rebuilding all dependencies for each build, the binaries are cached and reused when possible. Changes in the dependency-generator will trigger cache-invalidation and rebuilds as necessary.
