+= Build Systems
+
+The build system is the primary way for both developers and system integrators
+to interact with the Git project. As such, being easy to use and extend for
+those who are not directly developing Git itself is just as important as other
+requirements we have on any potential build system.
+
+This document outlines the different requirements that we have for the build
+system and then compares available build systems using these criteria.
+
+== Requirements
+
+The following subsections present a list of requirements that we have for any
+potential build system. Sections are sorted by decreasing priority.
+
+=== Platform support
+
+The build system must have support for all of our platforms that we continually
+test against as outlined by our platform support policy. These platforms are:
+
+  - Linux
+  - Windows
+  - macOS
+
+Furthermore, the build system should have support for the following platforms
+that generally have somebody running test pipelines against regularly:
+
+  - AIX
+  - FreeBSD
+  - NetBSD
+  - NonStop
+  - OpenBSD
+
+The platforms which must be supported by the tool should be aligned with our
+[platform support policy](platform-support.txt).
+
+=== Auto-detection of supported features
+
+The build system must support auto-detection of features which are or aren't
+available on the current platform. Platform maintainers should not be required
+to manually configure the complete build.
+
+Auto-detection of the following items is considered to be important:
+
+  - Check for the existence of headers.
+  - Check for the existence of libraries.
+  - Check for the existence of exectuables.
+  - Check for the runtime behavior of specific functions.
+  - Check for specific link order requirements when multiple libraries are
+    involved.
+
+=== Ease of use
+
+The build system should be both easy to use and easy to extend. While this is
+naturally a subjective metric it is likely not controversial to say that some
+build systems are considerably harder to use than others.
+
+=== IDE support
+
+The build system should integrate with well-known IDEs. Well-known IDEs include:
+
+  - Microsoft Visual Studio
+  - Visual Studio Code
+  - Xcode
+
+There are four levels of support:
+
+  - Native integration into the IDE.
+  - Integration into the IDE via a plugin.
+  - Integration into the IDE via generating a project description with the build
+    system.
+  - No integration.
+
+Native integration is preferable, but integration via either a plugin or by
+generating a project description via the build system are considered feasible
+alternatives.
+
+Another important distinction is the level of integration. There are two
+features that one generally wants to have:
+
+  - Integration of build targets.
+  - Automatic setup of features like code completion with detected build
+    dependencies.
+
+The first bullet point is the bare minimum, but is not sufficient to be
+considered proper integration.
+
+=== Out-of-tree builds
+
+The build system should support out-of-tree builds. Out-of-tree builds allow a
+developer to configure multiple different build directories with different
+configuration, e.g. one "debug" build and one "release" build.
+
+=== Cross-platform builds
+
+The build system should support cross-platform builds, e.g. building for arm on
+an x86-64 host.
+
+=== Language support
+
+The following languages and toolchains are of relevance and should be supported
+by the build system:
+
+  - C: the primary compiled language used by Git, must be supported. Relevant
+    toolchains are GCC, Clang and MSVC.
+  - Rust: candidate as a second compiled lanugage, should be supported. Relevant
+    toolchains is the LLVM-based rustc.
+
+Built-in support for the respective languages is preferred over support that
+needs to be wired up manually to avoid unnecessary complexity. Native support
+includes the following features:
+
+  - Compiling objects.
+  - Dependency tracking.
+  - Detection of available features.
+  - Discovery of relevant toolchains.
+  - Linking libraries and executables.
+  - Templating placeholders in scripts.
+
+=== Test integration
+
+It should be possible to integrate tests into the build system such that it is
+possible to build and test Git within the build system. Features which are nice
+to have:
+
+  - Track build-time dependencies for respective tests. Unit tests have
+    different requirements than integration tests.
+  - Allow filtering of which tests to run.
+  - Allow running tests such that utilities like `test_pause` or `debug` work.
+
+== Comparison
+
+The following list of build systems are considered:
+
+- GNU Make
+- autoconf
+- CMake
+- Meson
+
+=== GNU Make
+
+- Platform support: ubitquitous on all platforms, but not well-integrated into Windows.
+- Auto-detection: no built-in support for auto-detection of features.
+- Ease of use: easy to use, but discovering available options is hard. Makefile
+  rules can quickly get out of hand once reaching a certain scope.
+- IDE support: execution of Makefile targets is supported by many IDEs
+- Out-of-tree builds: supported in theory, not wired up in practice.
+- Cross-platform builds: supported in theory, not wired up in practice.
+- Language support:
+  - C: Limited built-in support, many parts need to be wired up manually.
+  - Rust: No built-in support, needs to be wired up manually.
+- Test integration: partially supported, many parts need to be wired up
+  manually.
+
+=== autoconf
+
+- Platform support: ubiquitous on all platforms, but not well-integrated into Windows.
+- Auto-detection: supported.
+- Ease of use: easy to use, discovering available options is comparatively
+  easy. The autoconf syntax is prohibitively hard to extend though due to its
+  complex set of interacting files and the hard-to-understand M4 language.
+- IDE support: no integration into IDEs at generation time. The generated
+  Makefiles have the same level of support as GNU Make.
+- Out-of-tree builds: supported in theory, not wired up in practice.
+- Cross-platform builds: supported.
+- Language support:
+  - C: Limited built-in support, many parts need to be wired up manually.
+  - Rust: No built-in support, needs to be wired up manually.
+- Test integration: partially supported, many parts need to be wired up
+  manually.
+
+=== CMake
+
+- Platform support: not as extensive as GNU Make or autoconf, but all major
+  platforms are supported.
+  - AIX
+  - Cygwin
+  - FreeBSD
+  - Linux
+  - OpenBSD
+  - Solaris
+  - Windows
+  - macOS
+- Ease of use: easy to use, discovering available options is not always
+  trivial. The scripting language used by CMake is somewhat cumbersome to use,
+  but extending CMake build instructions is doable.
+- IDE support: natively integrated into Microsoft Visual Studio. Can generate
+  project descriptions for Xcode. An extension is available for Visual Studio
+  Code. Many other IDEs have plugins for CMake.
+- Out-of-tree builds: supported.
+- Cross-platform builds: supported.
+- Language support:
+  - C: Supported for GCC, Clang, MSVC and other toolchains.
+  - Rust: No built-in support, needs to be wired up manually.
+- Test integration: supported, even though test dependencies are a bit
+  cumbersome to use via "test fixtures". Interactive test runs are not
+  supported.
+
+=== Meson
+
+- Platform: not as extensive as GNU Make or autoconf, but all major platforms
+  and some smaller ones are supported.
+  - AIX
+  - Cygwin
+  - DragonflyBSD
+  - FreeBSD
+  - Haiku
+  - Linux
+  - NetBSD
+  - OpenBSD
+  - Solaris
+  - Windows
+  - macOS
+- Ease of use: easy to use, discovering available options is easy. The
+  scripting language is straight-forward to use.
+- IDE support: Supports generating build instructions for Xcode and Microsoft
+  Visual Studio, a plugin exists for Visual Studio Code.
+- Out-of-tree builds: supported.
+- Cross-platform builds: supported.
+- Language support:
+  - C: Supported for GCC, Clang, MSVC and other toolchains.
+  - Rust: Supported for rustc.
+- Test integration: supported. Interactive tests are supported starting with
+  Meson 1.5.0 via the `--interactive` flag.

+# Meson build system
+# ==================
+#
+# The Meson build system is an alternative to our Makefile that you can use to
+# build, test and install Git. Using Meson results in a couple of benefits:
+#
+#  - Out-of-tree builds.
+#  - Better integration into IDEs.
+#  - Easy-to-use autoconfiguration of available features on your system.
+#
+# To use Meson from the command line you need to have both Meson and Ninja
+# installed. Alternatively, if you do not have Python available on your system,
+# you can also use Muon instead of Meson and Samurai instead of Ninja, both of
+# which are drop-ins replacement that only depend on C.
+#
+# Basic usage
+# ===========
+#
+# In the most trivial case, you can configure, build and install Git like this:
+#
+#  1. Set up the build directory. This only needs to happen once per build
+#     directory you want to have. You can also configure multiple different
+#     build directories with different configurations.
+#
+#      $ meson setup build/
+#
+#     The build directory gets ignored by Git automatically as Meson will write
+#     a ".gitignore" file into it. From hereon, we will assume that you execute
+#     commands inside this build directory.
+#
+# 2. Compile Git. You can either use Meson, Ninja or Samurai to do this, so all
+#    of the following invocations are equivalent:
+#
+#      $ meson compile
+#      $ ninja
+#      $ samu
+#
+#   The different invocations should ultimately not make much of a difference.
+#   Using Meson also works with other generators though, like when the build
+#   directory has been set up for use with Microsoft Visual Studio.
+#
+#   Ninja and Samurai use multiple jobs by default, scaling with the number of
+#   processor cores available. You can pass the `-jN` flag to change this.
+#
+#   Meson automatically picks up ccache and sccache when these are installed
+#   when setting up the build directory. You can override this behaviour when
+#   setting up the build directory by setting the `CC` environment variable to
+#   your desired compiler.
+#
+# 3. Execute tests. Again, you can either use Meson, Ninja or Samurai to do this:
+#
+#      $ meson test
+#      $ ninja test
+#      $ samu test
+#
+#   It is recommended to use Meson in this case though as it also provides you
+#   additional features that the other build systems don't have available.
+#   You can e.g. pass additional arguments to the test executables or run
+#   individual tests:
+#
+#      # Execute the t0000-basic integration test and t-reftable-stack unit test.
+#      $ meson test t0000-basic t-reftable-stack
+#
+#      # Execute all reftable unit tests.
+#      $ meson test t-reftable-*
+#
+#      # Execute all tests and stop with the first failure.
+#      $ meson test --maxfail 1
+#
+#      # Execute single test interactively such that features like `debug ()` work.
+#      $ meson test -i --test-args='-ix' t1400-update-ref
+#
+#   Test execution is parallelized by default and scales with the number of
+#   processor cores available. You can change the number of processes by passing
+#   the `-jN` flag to `meson test`.
+#
+# 4. Install the Git distribution. Again, this can be done via Meson, Ninja or
+#    Samurai:
+#
+#      $ meson install
+#      $ ninja install
+#      $ samu install
+#
+#    The prefix into which Git shall be installed is defined when setting up
+#    the build directory. More on that in the "Configuration" section.
+#
+# Meson supports multiple backends. The default backend generates Ninja build
+# instructions, but it also supports the generation of Microsoft Visual
+# Studio solutions as well as Xcode projects by passing the `--backend` option
+# to `meson setup`. IDEs like Eclipse and Visual Studio Code provide plugins to
+# import Meson files directly.
+#
+# Configuration
+# =============
+#
+# The exact configuration of Git is determined when setting up the build
+# directory via `meson setup`. Unless told otherwise, Meson will automatically
+# detect the availability of various bits and pieces. There are two different
+# kinds of options that can be used to further tweak the build:
+#
+#   - Built-in options provided by Meson.
+#
+#   - Options defined by the project in the "meson_options.txt" file.
+#
+# Both kinds of options can be inspected by running `meson configure` in the
+# build directory, which will give you a list of the current value for all
+# options.
+#
+# Options can be configured either when setting up the build directory or can
+# be changed in preexisting build directories:
+#
+#      # Set up a new build directory with optimized settings that will be
+#      # installed into an alternative prefix.
+#      $ meson setup --buildtype release --optimization 3 --strip --prefix=/home/$USER build
+#
+#      # Set up a new build directory with a higher warning level. Level 2 is
+#      # mostly equivalent to setting DEVELOPER=1, level 3 and "everything"
+#      # will enable even more warnings.
+#      $ meson setup -Dwarning_level=2 build
+#
+#      # Set up a new build directory with 'address' and 'undefined' sanitizers
+#      # using Clang.
+#      $ CC=clang meson setup -Db_sanitize=address,undefined build
+#
+#      # Disable tests in a preexisting build directory.
+#      $ meson configure -Dtests=false
+#
+#      # Disable features based on Python
+#      $ meson configure -Dpython=disabled
+#
+# Options have a type like booleans, choices, strings or features. Features are
+# somewhat special as they can have one of three values: enabled, disabled or
+# auto. While the first two values are self-explanatory, "auto" will enable or
+# disable the feature based on the availability of prerequisites to support it.
+# Python-based features for example will be enabled automatically when a Python
+# interpreter could be found. The default value of such features can be changed
+# via `meson setup --auto-features={enabled,disabled,auto}`, which will set the
+# value of all features with a value of "auto" to the provided one by default.
+#
+# It is also possible to store a set of configuration options in machine files.
+# This can be useful in case you regularly want to reuse the same set of options:
+#
+#   [binaries]
+#   c = ['clang']
+#   ar = ['ar']
+#
+#   [project options]
+#   gettext = 'disabled'
+#   default_editor = 'vim'
+#
+#   [built-in options]
+#   b_lto = true
+#   b_sanitize = 'address,undefined'
+#
+# These machine files can be passed to `meson setup` via the `--native-file`
+# option.
+#
+# Subproject wrappers
+# ===================
+#
+# Subproject wrappers are a feature provided by Meson that allows the automatic
+# fallback to a "wrapped" dependency in case the dependency is not provided by
+# the system. For example if the system is lacking curl, then Meson will use
+# "subprojects/curl.wrap" to set up curl as a subproject and compile and link
+# the dependency into Git itself. This is especially helpful on systems like
+# Windows, where you typically don't have such dependencies installed.
+#
+# The use of subproject wrappers can be disabled by executing `meson setup`
+# with the `--wrap-mode nofallback` option.
