+Introduction
+============
+
+One problem that CMake users often face is sharing settings with other people
+for common ways to configure a project. This may be done to support CI builds,
+or for users who frequently use the same build. CMake supports two files,
+``CMakePresets.json`` and ``CMakeUserPresets.json``, that allow users to
+specify common configure options and share them with others.
+
+``CMakePresets.json`` and ``CMakeUserPresets.json`` live in the project's root
+directory. They both have exactly the same format, and both are optional
+(though at least one must be present if ``--preset`` is specified.)
+``CMakePresets.json`` is meant to save project-wide builds, while
+``CMakeUserPresets.json`` is meant for developers to save their own local
+builds. ``CMakePresets.json`` may be checked into a version control system, and
+``CMakeUserPresets.json`` should NOT be checked in. For example, if a project
+is using Git, ``CMakePresets.json`` may be tracked, and
+``CMakeUserPresets.json`` should be added to the ``.gitignore``.
+
+Format
+======
+
+ The files are a JSON document with an object as the root:
+
+ .. literalinclude:: presets/example.json
+ :language: json
+
+ The root object recognizes the following fields:
+
+ ``version``
+
+ A required integer representing the version of the JSON schema. Currently,
+ the only supported version is 1.
+
+ ``cmakeMinimumRequired``
+
+ An optional object representing the minimum version of CMake needed to
+ build this project. This object consists of the following fields:
+
+ ``major``
+
+ An optional integer representing the major version.
+
+ ``minor``
+
+ An optional integer representing the minor version.
+
+ ``patch``
+
+ An optional integer representing the patch version.
+
+ ``vendor``
+
+ An optional map containing vendor-specific information. CMake does not
+ interpret the contents of this field except to verify that it is a map if
+ it does exist. However, the keys should be a vendor-specific domain name
+ followed by a ``/``-separated path. For example, the Example IDE 1.0 could
+ use ``example.com/ExampleIDE/1.0``. The value of each field can be anything
+ desired by the vendor, though will typically be a map.
+
+ ``configurePresets``
+
+ An optional array of configure preset objects. Each preset may contain the
+ following fields:
+
+ ``name``
+
+ A required string representing the machine-friendly name of the preset.
+ This identifier is used in the ``--preset`` argument. There must not be
+ two presets in the union of ``CMakePresets.json`` and
+ ``CMakeUserPresets.json`` in the same directory with the same name.
+
+ ``hidden``
+
+ An optional boolean specifying whether or not a preset should be hidden.
+ If a preset is hidden, it cannot be used in the ``--preset=`` argument,
+ will not show up in the :manual:`CMake GUI <cmake-gui(1)>`, and does not
+ have to have a valid ``generator`` or ``binaryDir``, even from
+ inheritance. ``hidden`` presets are intended to be used as a base for
+ other presets to inherit via the ``inherits`` field.
+
+ ``inherits``
+
+ An optional array of strings representing the names of presets to inherit
+ from. The preset will inherit all of the fields from the ``inherits``
+ presets by default (except ``name``, ``hidden``, ``inherits``,
+ ``description``, and ``longDescription``), but can override them as
+ desired. If multiple ``inherits`` presets provide conflicting values for
+ the same field, the earlier preset in the ``inherits`` list will be
+ preferred. Presets in ``CMakePresets.json`` may not inherit from presets
+ in ``CMakeUserPresets.json``.
+
+ This field can also be a string, which is equivalent to an array
+ containing one string.
+
+ ``vendor``
+
+ An optional map containing vendor-specific information. CMake does not
+ interpret the contents of this field except to verify that it is a map
+ if it does exist. However, it should follow the same conventions as the
+ root-level ``vendor`` field. If vendors use their own per-preset
+ ``vendor`` field, they should implement inheritance in a sensible manner
+ when appropriate.
+
+ ``displayName``
+
+ An optional string with a human-friendly name of the preset.
+
+ ``description``
+
+ An optional string with a human-friendly description of the preset.
+
+ ``generator``
+
+ An optional string representing the generator to use for the preset. If
+ ``generator`` is not specified, it must be inherited from the
+ ``inherits`` preset (unless this preset is ``hidden``).
+
+ Note that for Visual Studio generators, unlike in the command line ``-G``
+ argument, you cannot include the platform name in the generator name. Use
+ the ``architecture`` field instead.
+
+ ``architecture``
+
+ An optional string representing the platform name to use for generators
+ that support platforms.
+
+ ``toolset``
+
+ An optional string representing the toolset name to use for generators
+ that support toolsets.
+
+ ``cmakeGeneratorConfig``
+
+ An optional string telling CMake how to handle the ``architecture`` and
+ ``toolset`` fields. Valid values are:
+
+ ``"default"``
+
+ Set the platform and toolset using the ``architecture`` and ``toolset``
+ fields respectively. On non-Visual Studio generators, this will result
+ in an error if ``architecture`` or ``toolset`` are set.
+
+ ``"ignore"``
+
+ Do not set the platform or toolset at all, even on Visual Studio
+ generators. This is useful if, for example, a preset uses the Ninja
+ generator, and an IDE knows how to set up the Visual C++ environment
+ from the ``architecture`` and ``toolset`` fields. In that case, CMake
+ will ignore ``architecture`` and ``toolset``, but the IDE can use them
+ to set up the environment before invoking CMake.
+
+ ``binaryDir``
+
+ An optional string representing the path to the output binary directory.
+ This field supports macro expansion. If a relative path is specified, it
+ is calculated relative to the source directory. If ``binaryDir`` is not
+ specified, it must be inherited from the ``inherits`` preset (unless this
+ preset is ``hidden``).
+
+ ``cmakeExecutable``
+
+ An optional string representing the path to the CMake executable to use
+ for this preset. This is reserved for use by IDEs, and is not used by
+ CMake itself. IDEs that use this field should expand any macros in it.
+
+ ``cacheVariables``
+
+ An optional map of cache variables. The key is the variable name (which
+ may not be an empty string), and the value is either ``null``, a string
+ representing the value of the variable (which supports macro expansion),
+ or an object with the following fields:
+
+ ``type``
+
+ An optional string representing the type of the variable.
+
+ ``value``
+
+ A required string representing the value of the variable. This field
+ supports macro expansion.
+
+ Cache variables are inherited through the ``inherits`` field, and the
+ preset's variables will be the union of its own ``cacheVariables`` and
+ the ``cacheVariables`` from all its parents. If multiple presets in this
+ union define the same variable, the standard rules of ``inherits`` are
+ applied. Setting a variable to ``null`` causes it to not be set, even if
+ a value was inherited from another preset.
+
+ ``environment``
+
+ An optional map of environment variables. The key is the variable name
+ (which may not be an empty string), and the value is either ``null`` or
+ a string representing the value of the variable. Each variable is set
+ regardless of whether or not a value was given to it by the process's
+ environment. This field supports macro expansion, and environment
+ variables in this map may reference each other, and may be listed in any
+ order, as long as such references do not cause a cycle (for example,
+ if ``ENV_1`` is ``$env{ENV_2}``, ``ENV_2`` may not be ``$env{ENV_1}``.)
+
+ Environment variables are inherited through the ``inherits`` field, and
+ the preset's environment will be the union of its own ``environment`` and
+ the ``environment`` from all its parents. If multiple presets in this
+ union define the same variable, the standard rules of ``inherits`` are
+ applied. Setting a variable to ``null`` causes it to not be set, even if
+ a value was inherited from another preset.
+
+ ``warnings``
+
+ An optional object specifying the warnings to enable. The object may
+ contain the following fields:
+
+ ``dev``
+
+ An optional boolean. Equivalent to passing ``-Wdev`` or ``-Wno-dev``
+ on the command line. This may not be set to ``false`` if ``errors.dev``
+ is set to ``true``.
+
+ ``deprecated``
+
+ An optional boolean. Equivalent to passing ``-Wdeprecated`` or
+ ``-Wno-deprecated`` on the command line. This may not be set to
+ ``false`` if ``errors.deprecated`` is set to ``true``.
+
+ ``uninitialized``
+
+ An optional boolean. Setting this to ``true`` is equivalent to passing
+ ``--warn-uninitialized`` on the command line.
+
+ ``unusedCli``
+
+ An optional boolean. Setting this to ``false`` is equivalent to passing
+ ``--no-warn-unused-cli`` on the command line.
+
+ ``systemVars``
+
+ An optional boolean. Setting this to ``true`` is equivalent to passing
+ ``--check-system-vars`` on the command line.
+
+ ``errors``
+
+ An optional object specifying the errors to enable. The object may
+ contain the following fields:
+
+ ``dev``
+
+ An optional boolean. Equivalent to passing ``-Werror=dev`` or
+ ``-Wno-error=dev`` on the command line. This may not be set to ``true``
+ if ``warnings.dev`` is set to ``false``.
+
+ ``deprecated``
+
+ An optional boolean. Equivalent to passing ``-Werror=deprecated`` or
+ ``-Wno-error=deprecated`` on the command line. This may not be set to
+ ``true`` if ``warnings.deprecated`` is set to ``false``.
+
+ ``debug``
+
+ An optional object specifying debug options. The object may contain the
+ following fields:
+
+ ``output``
+
+ An optional boolean. Setting this to ``true`` is equivalent to passing
+ ``--debug-output`` on the command line.
+
+ ``tryCompile``
+
+ An optional boolean. Setting this to ``true`` is equivalent to passing
+ ``--debug-trycompile`` on the command line.
+
+ ``find``
+
+ An optional boolean. Setting this to ``true`` is equivalent to passing
+ ``--debug-find`` on the command line.
+
+ As mentioned above, some fields support macro expansion. Macros are
+ recognized in the form ``$<macro-namespace>{<macro-name>}``. All macros are
+ evaluated in the context of the preset being used, even if the macro is in a
+ field that was inherited from another preset. For example, if the ``Base``
+ preset sets variable ``PRESET_NAME`` to ``${presetName}``, and the
+ ``Derived`` preset inherits from ``Base``, ``PRESET_NAME`` will be set to
+ ``Derived``.
+
+ It is an error to not put a closing brace at the end of a macro name. For
+ example, ``${sourceDir`` is invalid. A dollar sign (``$``) followed by
+ anything other than a left curly brace (``{``) with a possible namespace is
+ interpreted as a literal dollar sign.
+
+ Recognized macros include:
+
+ ``${sourceDir}``
+
+ Path to the project source directory.
+
+ ``${sourceParentDir}``
+
+ Path to the project source directory's parent directory.
+
+ ``${presetName}``
+
+ Name specified in the preset's ``name`` field.
+
+ ``${generator}``
+
+ Generator specified in the preset's ``generator`` field.
+
+ ``${dollar}``
+
+ A literal dollar sign (``$``).
+
+ ``$env{<variable-name>}``
+
+ Environment variable with name ``<variable-name>``. The variable name may
+ not be an empty string. If the variable is defined in the ``environment``
+ field, that value is used instead of the value from the parent environment.
+ If the environment variable is not defined, this evaluates as an empty
+ string.
+
+ Note that while Windows environment variable names are case-insensitive,
+ variable names within a preset are still case-sensitive. This may lead to
+ unexpected results when using inconsistent casing. For best results, keep
+ the casing of environment variable names consistent.
+
+ ``$penv{<variable-name>}``
+
+ Similar to ``$env{<variable-name>}``, except that the value only comes from
+ the parent environment, and never from the ``environment`` field. This
+ allows you to prepend or append values to existing environment variables.
+ For example, setting ``PATH`` to ``/path/to/ninja/bin:$penv{PATH}`` will
+ prepend ``/path/to/ninja/bin`` to the ``PATH`` environment variable. This
+ is needed because ``$env{<variable-name>}`` does not allow circular
+ references.
+
+ ``$vendor{<macro-name>}``
+
+ An extension point for vendors to insert their own macros. CMake will not
+ be able to use presets which have a ``$vendor{<macro-name>}`` macro, and
+ effectively ignores such presets. However, it will still be able to use
+ other presets from the same file.
+
+ CMake does not make any attempt to interpret ``$vendor{<macro-name>}``
+ macros. However, to avoid name collisions, IDE vendors should prefix
+ ``<macro-name>`` with a very short (preferably <= 4 characters) vendor
+ identifier prefix, followed by a ``.``, followed by the macro name. For
+ example, the Example IDE could have ``$vendor{xide.ideInstallDir}``.

- the parent environment, and never from the ``environment`` field. This
- allows you to prepend or append values to existing environment variables.
- For example, setting ``PATH`` to ``/path/to/ninja/bin:$penv{PATH}`` will
- prepend ``/path/to/ninja/bin`` to the ``PATH`` environment variable. This
- is needed because ``$env{<variable-name>}`` does not allow circular
- references.
-
- ``$vendor{<macro-name>}``
-
- An extension point for vendors to insert their own macros. CMake will not
- be able to use presets which have a ``$vendor{<macro-name>}`` macro, and
- effectively ignores such presets. However, it will still be able to use
- other presets from the same file.
-
- CMake does not make any attempt to interpret ``$vendor{<macro-name>}``
- macros. However, to avoid name collisions, IDE vendors should prefix
- ``<macro-name>`` with a very short (preferably <= 4 characters) vendor
- identifier prefix, followed by a ``.``, followed by the macro name. For
- example, the Example IDE could have ``$vendor{xide.ideInstallDir}``.
-
In all cases the ``<options>`` may be zero or more of the `Options`_ below.
