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 main files,
<code class="docutils literal notranslate">CMakePresets.json</code> and <code class="docutils literal notranslate">CMakeUserPresets.json</code>, that allow users to
specify common configure options and share them with others. CMake also
supports files included with the <code class="docutils literal notranslate">include</code> field.
<code class="docutils literal notranslate">CMakePresets.json</code> and <code class="docutils literal notranslate">CMakeUserPresets.json</code> 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 <a class="reference internal" href="cmake.1.html#cmdoption-cmake-preset"><code class="xref std std-option docutils literal notranslate">--preset</code></a>
is specified). <code class="docutils literal notranslate">CMakePresets.json</code> is meant to specify project-wide build
details, while <code class="docutils literal notranslate">CMakeUserPresets.json</code> is meant for developers to specify
their own local build details.
<code class="docutils literal notranslate">CMakePresets.json</code> may be checked into a version control system, and
<code class="docutils literal notranslate">CMakeUserPresets.json</code> should NOT be checked in. For example, if a
project is using Git, <code class="docutils literal notranslate">CMakePresets.json</code> may be tracked, and
<code class="docutils literal notranslate">CMakeUserPresets.json</code> should be added to the <code class="docutils literal notranslate">.gitignore</code>.

<dt><code class="docutils literal notranslate">cmakeMinimumRequired</code></dt><dd>An optional object representing the minimum version of CMake needed to
build this project. This object consists of the following fields:
<dl class="simple">
<dt><code class="docutils literal notranslate">major</code></dt><dd>An optional integer representing the major version.
</dd>

</dd>
<dt><code class="docutils literal notranslate">include</code></dt><dd>An optional array of strings representing files to include. If the filenames
are not absolute, they are considered relative to the current file.
This is allowed in preset files specifying version <code class="docutils literal notranslate">4</code> or above.
See <a class="reference internal" href="#includes">Includes</a> for discussion of the constraints on included files.
</dd>
<dt><code class="docutils literal notranslate">vendor</code></dt><dd>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 <code class="docutils literal notranslate">/</code>-separated path. For example, the Example IDE 1.0 could
use <code class="docutils literal notranslate">example.com/ExampleIDE/1.0</code>. The value of each field can be anything
desired by the vendor, though will typically be a map.
</dd>
<dt><code class="docutils literal notranslate">configurePresets</code></dt><dd>An optional array of <a class="reference internal" href="#configure-preset">Configure Preset</a> objects.

<code class="docutils literal notranslate">CMakePresets.json</code> and <code class="docutils literal notranslate">CMakeUserPresets.json</code> can include other files
with the <code class="docutils literal notranslate">include</code> field in file version <code class="docutils literal notranslate">4</code> and later. Files included
by these files can also include other files. If <code class="docutils literal notranslate">CMakePresets.json</code> and
<code class="docutils literal notranslate">CMakeUserPresets.json</code> are both present, <code class="docutils literal notranslate">CMakeUserPresets.json</code>
implicitly includes <code class="docutils literal notranslate">CMakePresets.json</code>, even with no <code class="docutils literal notranslate">include</code> field,
in all versions of the format.
If a preset file contains presets that inherit from presets in another file,
the file must include the other file either directly or indirectly.
Include cycles are not allowed among files. If <code class="docutils literal notranslate">a.json</code> includes
<code class="docutils literal notranslate">b.json</code>, <code class="docutils literal notranslate">b.json</code> cannot include <code class="docutils literal notranslate">a.json</code>. However, a file may be
included multiple times from the same file or from different files.
Files directly or indirectly included from <code class="docutils literal notranslate">CMakePresets.json</code> should be
guaranteed to be provided by the project. <code class="docutils literal notranslate">CMakeUserPresets.json</code> may
include files from anywhere.

<section id="configure-preset">
<h3><a class="toc-backref" href="#id6" role="doc-backlink">Configure Preset</a><a class="headerlink" href="#configure-preset" title="Permalink to this heading">¶</a></h3>
Each entry of the <code class="docutils literal notranslate">configurePresets</code> array is a JSON object
that may contain the following fields:
<dl>
<dt><code class="docutils literal notranslate">name</code></dt><dd>A required string representing the machine-friendly name of the preset.
This identifier is used in the <a class="reference internal" href="cmake.1.html#cmake-options">cmake --preset</a> option.
There must not be two configure presets in the union of <code class="docutils literal notranslate">CMakePresets.json</code>
and <code class="docutils literal notranslate">CMakeUserPresets.json</code> in the same directory with the same name.
However, a configure preset may have the same name as a build, test,
package, or workflow preset.
</dd>
<dt><code class="docutils literal notranslate">hidden</code></dt><dd>An optional boolean specifying whether or not a preset should be hidden.
If a preset is hidden, it cannot be used in the <code class="docutils literal notranslate">--preset=</code> argument,
will not show up in the <a class="reference internal" href="cmake-gui.1.html#manual:cmake-gui(1)" title="cmake-gui(1)"><code class="xref cmake cmake-manual docutils literal notranslate">CMake GUI</code></a>, and does not
have to have a valid <code class="docutils literal notranslate">generator</code> or <code class="docutils literal notranslate">binaryDir</code>, even from
inheritance. <code class="docutils literal notranslate">hidden</code> presets are intended to be used as a base for
other presets to inherit via the <code class="docutils literal notranslate">inherits</code> field.
</dd>
<dt><code class="docutils literal notranslate">inherits</code></dt><dd>An optional array of strings representing the names of presets to inherit
from. This field can also be a string, which is equivalent to an array
containing one string.
The preset will inherit all of the fields from the <code class="docutils literal notranslate">inherits</code>
presets by default (except <code class="docutils literal notranslate">name</code>, <code class="docutils literal notranslate">hidden</code>, <code class="docutils literal notranslate">inherits</code>,
<code class="docutils literal notranslate">description</code>, and <code class="docutils literal notranslate">displayName</code>), but can override them as
desired. If multiple <code class="docutils literal notranslate">inherits</code> presets provide conflicting values for
the same field, the earlier preset in the <code class="docutils literal notranslate">inherits</code> array will be
preferred.
A preset can only inherit from another preset that is defined in the
same file or in one of the files it includes (directly or indirectly).
Presets in <code class="docutils literal notranslate">CMakePresets.json</code> may not inherit from presets in
<code class="docutils literal notranslate">CMakeUserPresets.json</code>.
</dd>
<dt><code class="docutils literal notranslate">condition</code></dt><dd>An optional <a class="reference internal" href="#condition">Condition</a> object. This is allowed in preset files specifying
version <code class="docutils literal notranslate">3</code> or above.
</dd>
<dt><code class="docutils literal notranslate">vendor</code></dt><dd>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 <code class="docutils literal notranslate">vendor</code> field. If vendors use their own per-preset
<code class="docutils literal notranslate">vendor</code> field, they should implement inheritance in a sensible manner
when appropriate.
</dd>
<dt><code class="docutils literal notranslate">displayName</code></dt><dd>An optional string with a human-friendly name of the preset.
</dd>
<dt><code class="docutils literal notranslate">description</code></dt><dd>An optional string with a human-friendly description of the preset.
</dd>
<dt><code class="docutils literal notranslate">generator</code></dt><dd>An optional string representing the generator to use for the preset. If
<code class="docutils literal notranslate">generator</code> is not specified, it must be inherited from the
<code class="docutils literal notranslate">inherits</code> preset (unless this preset is <code class="docutils literal notranslate">hidden</code>). In version <code class="docutils literal notranslate">3</code>
or above, this field may be omitted to fall back to regular generator
discovery procedure.
Note that for Visual Studio generators, unlike in the command line
<a class="reference internal" href="cmake.1.html#cmdoption-cmake-G"><code class="xref std std-option docutils literal notranslate">-G</code></a> argument, you cannot include the platform name
in the generator name. Use the <code class="docutils literal notranslate">architecture</code> field instead.
</dd>
<dt><code class="docutils literal notranslate">architecture</code>, <code class="docutils literal notranslate">toolset</code></dt><dd>Optional fields representing the platform and toolset, respectively, for
<a class="reference internal" href="cmake-generators.7.html#manual:cmake-generators(7)" title="cmake-generators(7)"><code class="xref cmake cmake-manual docutils literal notranslate">generators</code></a> that support them.
See <a class="reference internal" href="cmake.1.html#cmdoption-cmake-A"><code class="xref std std-option docutils literal notranslate">cmake -A</code></a> option for possible values for <code class="docutils literal notranslate">architecture</code>
and <a class="reference internal" href="cmake.1.html#cmdoption-cmake-T"><code class="xref std std-option docutils literal notranslate">cmake -T</code></a> for <code class="docutils literal notranslate">toolset</code>.
Each may be either a string or an object with the following fields:
<dl>
<dt><code class="docutils literal notranslate">value</code></dt><dd>An optional string representing the value.
</dd>
<dt><code class="docutils literal notranslate">strategy</code></dt><dd>An optional string telling CMake how to handle the <code class="docutils literal notranslate">architecture</code> or
<code class="docutils literal notranslate">toolset</code> field. Valid values are:
<dl class="simple">
<dt><code class="docutils literal notranslate">&quot;set&quot;</code></dt><dd>Set the respective value. This will result in an error for generators
that do not support the respective field.
</dd>
<dt><code class="docutils literal notranslate">&quot;external&quot;</code></dt><dd>Do not set the value, even if the generator supports it. 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
<code class="docutils literal notranslate">architecture</code> and <code class="docutils literal notranslate">toolset</code> fields. In that case, CMake will
ignore the field, but the IDE can use them to set up the environment
before invoking CMake.
</dd>
</dl>
If no <code class="docutils literal notranslate">strategy</code> field is given, or if the field uses the string form
rather than the object form, the behavior is the same as <code class="docutils literal notranslate">&quot;set&quot;</code>.
</dd>
</dl>
</dd>
<dt><code class="docutils literal notranslate">toolchainFile</code></dt><dd>An optional string representing the path to the toolchain file.
This field supports <a class="reference internal" href="#macro-expansion">macro expansion</a>. If a relative path is specified,
it is calculated relative to the build directory, and if not found,
relative to the source directory. This field takes precedence over any
<a class="reference internal" href="../variable/CMAKE_TOOLCHAIN_FILE.html#variable:CMAKE_TOOLCHAIN_FILE" title="CMAKE_TOOLCHAIN_FILE"><code class="xref cmake cmake-variable docutils literal notranslate">CMAKE_TOOLCHAIN_FILE</code></a> value. It is allowed in preset files
specifying version <code class="docutils literal notranslate">3</code> or above.
</dd>
<dt><code class="docutils literal notranslate">binaryDir</code></dt><dd>An optional string representing the path to the output binary directory.
This field supports <a class="reference internal" href="#macro-expansion">macro expansion</a>. If a relative path is specified,
it is calculated relative to the source directory. If <code class="docutils literal notranslate">binaryDir</code> is not
specified, it must be inherited from the <code class="docutils literal notranslate">inherits</code> preset (unless this
preset is <code class="docutils literal notranslate">hidden</code>). In version <code class="docutils literal notranslate">3</code> or above, this field may be
omitted.
</dd>
<dt><code class="docutils literal notranslate">installDir</code></dt><dd>An optional string representing the path to the installation directory.
This field supports <a class="reference internal" href="#macro-expansion">macro expansion</a>. If a relative path is specified,
it is calculated relative to the source directory. This is allowed in
preset files specifying version <code class="docutils literal notranslate">3</code> or above.
</dd>
<dt><code class="docutils literal notranslate">cmakeExecutable</code></dt><dd>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.
</dd>
<dt><code class="docutils literal notranslate">cacheVariables</code></dt><dd>An optional map of cache variables. The key is the variable name (which
may not be an empty string), and the value is either <code class="docutils literal notranslate">null</code>, a boolean
(which is equivalent to a value of <code class="docutils literal notranslate">&quot;TRUE&quot;</code> or <code class="docutils literal notranslate">&quot;FALSE&quot;</code> and a type
of <code class="docutils literal notranslate">BOOL</code>), a string representing the value of the variable (which
supports <a class="reference internal" href="#macro-expansion">macro expansion</a>), or an object with the following fields:
<dl class="simple">
<dt><code class="docutils literal notranslate">type</code></dt><dd>An optional string representing the type of the variable.

For a CMake project using ExternalProject with a configuration preset

preset that inherits that configuration preset or the ExternalProject
will not have the environment variables set in the configuration preset.

preset environment variables <code class="docutils literal notranslate">CC</code> and <code class="docutils literal notranslate">CXX</code> and use a build preset

Package presets may be used in schema version <code class="docutils literal notranslate">6</code> or above. Each entry of

fields:
<dl>
<dt><code class="docutils literal notranslate">name</code></dt><dd>A required string representing the machine-friendly name of the preset.
This identifier is used in the <a class="reference internal" href="cpack.1.html#cmdoption-cpack-preset"><code class="xref std std-option docutils literal notranslate">cpack --preset</code></a> option.
There must not be two package presets in the union of <code class="docutils literal notranslate">CMakePresets.json</code>
and <code class="docutils literal notranslate">CMakeUserPresets.json</code> in the same directory with the same name.
However, a package preset may have the same name as a configure, build,
test, or workflow preset.
</dd>
<dt><code class="docutils literal notranslate">hidden</code></dt><dd>An optional boolean specifying whether or not a preset should be hidden.
If a preset is hidden, it cannot be used in the
<a class="reference internal" href="cpack.1.html#cmdoption-cpack-preset"><code class="xref std std-option docutils literal notranslate">--preset</code></a> argument
and does not have to have a valid <code class="docutils literal notranslate">configurePreset</code>, even from
inheritance. <code class="docutils literal notranslate">hidden</code> presets are intended to be used as a base for
other presets to inherit via the <code class="docutils literal notranslate">inherits</code> field.
</dd>
<dt><code class="docutils literal notranslate">inherits</code></dt><dd>An optional array of strings representing the names of presets to inherit
from. This field can also be a string, which is equivalent to an array
containing one string.
The preset will inherit all of the fields from the
<code class="docutils literal notranslate">inherits</code> presets by default (except <code class="docutils literal notranslate">name</code>, <code class="docutils literal notranslate">hidden</code>,
<code class="docutils literal notranslate">inherits</code>, <code class="docutils literal notranslate">description</code>, and <code class="docutils literal notranslate">displayName</code>), but can override
them as desired. If multiple <code class="docutils literal notranslate">inherits</code> presets provide conflicting
values for the same field, the earlier preset in the <code class="docutils literal notranslate">inherits</code> array
will be preferred.
A preset can only inherit from another preset that is defined in the
same file or in one of the files it includes (directly or indirectly).
Presets in <code class="docutils literal notranslate">CMakePresets.json</code> may not inherit from presets in
<code class="docutils literal notranslate">CMakeUserPresets.json</code>.

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 <code class="docutils literal notranslate">vendor</code> field. If vendors use their own per-preset
<code class="docutils literal notranslate">vendor</code> field, they should implement inheritance in a sensible manner
when appropriate.

</dd>
<dt><code class="docutils literal notranslate">environment</code></dt><dd>An optional map of environment variables. The key is the variable name
(which may not be an empty string), and the value is either <code class="docutils literal notranslate">null</code> 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
<code class="docutils literal notranslate">ENV_1</code> is <code class="docutils literal notranslate">$env{ENV_2}</code>, <code class="docutils literal notranslate">ENV_2</code> may not be <code class="docutils literal notranslate">$env{ENV_1}</code>.)
Environment variables are inherited through the <code class="docutils literal notranslate">inherits</code> field, and
the preset's environment will be the union of its own <code class="docutils literal notranslate">environment</code>
and the <code class="docutils literal notranslate">environment</code> from all its parents. If multiple presets in
this union define the same variable, the standard rules of <code class="docutils literal notranslate">inherits</code>
are applied. Setting a variable to <code class="docutils literal notranslate">null</code> causes it to not be set,
even if a value was inherited from another preset.
</dd>
<dt><code class="docutils literal notranslate">configurePreset</code></dt><dd>An optional string specifying the name of a configure preset to
associate with this package preset. If <code class="docutils literal notranslate">configurePreset</code> is not
specified, it must be inherited from the inherits preset (unless this
preset is hidden). The build directory is inferred from the configure
preset, so packaging will run in the same <code class="docutils literal notranslate">binaryDir</code> that the
configuration did and build did.
</dd>

variables from the associated configure preset are inherited after all
inherited package preset environments, but before environment variables
explicitly specified in this package preset.

<dl class="simple">
<dt><code class="docutils literal notranslate">debug</code></dt><dd>An optional boolean specifying whether or not to print debug information.
A value of <code class="docutils literal notranslate">true</code> is equivalent to passing

<h3><a class="toc-backref" href="#id12" role="doc-backlink">Macro Expansion</a><a class="headerlink" href="#macro-expansion" title="Permalink to this heading">¶</a></h3>
As mentioned above, some fields support macro expansion. Macros are
recognized in the form <code class="docutils literal notranslate">$&lt;macro-namespace&gt;{&lt;macro-name&gt;}</code>. All macros are
evaluated in the context of the preset being used, even if the macro is in a
field that was inherited from another preset. For example, if the <code class="docutils literal notranslate">Base</code>
preset sets variable <code class="docutils literal notranslate">PRESET_NAME</code> to <code class="docutils literal notranslate">${presetName}</code>, and the
<code class="docutils literal notranslate">Derived</code> preset inherits from <code class="docutils literal notranslate">Base</code>, <code class="docutils literal notranslate">PRESET_NAME</code> will be set to
<code class="docutils literal notranslate">Derived</code>.
It is an error to not put a closing brace at the end of a macro name. For
example, <code class="docutils literal notranslate">${sourceDir</code> is invalid. A dollar sign (<code class="docutils literal notranslate">$</code>) followed by
anything other than a left curly brace (<code class="docutils literal notranslate">{</code>) with a possible namespace is
interpreted as a literal dollar sign.
Recognized macros include:
<dl>
<dt><code class="docutils literal notranslate">${sourceDir}</code></dt><dd>Path to the project source directory (i.e. the same as
<a class="reference internal" href="../variable/CMAKE_SOURCE_DIR.html#variable:CMAKE_SOURCE_DIR" title="CMAKE_SOURCE_DIR"><code class="xref cmake cmake-variable docutils literal notranslate">CMAKE_SOURCE_DIR</code></a>).
</dd>
<dt><code class="docutils literal notranslate">${sourceParentDir}</code></dt><dd>Path to the project source directory's parent directory.
</dd>
<dt><code class="docutils literal notranslate">${sourceDirName}</code></dt><dd>The last filename component of <code class="docutils literal notranslate">${sourceDir}</code>. For example, if
<code class="docutils literal notranslate">${sourceDir}</code> is <code class="docutils literal notranslate">/path/to/source</code>, this would be <code class="docutils literal notranslate">source</code>.
</dd>
<dt><code class="docutils literal notranslate">${presetName}</code></dt><dd>Name specified in the preset's <code class="docutils literal notranslate">name</code> field.
</dd>
<dt><code class="docutils literal notranslate">${generator}</code></dt><dd>Generator specified in the preset's <code class="docutils literal notranslate">generator</code> field. For build and

<dt><code class="docutils literal notranslate">${dollar}</code></dt><dd>A literal dollar sign (<code class="docutils literal notranslate">$</code>).
</dd>
<dt><code class="docutils literal notranslate">${pathListSep}</code></dt><dd>Native character for separating lists of paths, such as <code class="docutils literal notranslate">:</code> or <code class="docutils literal notranslate">;</code>.
For example, by setting <code class="docutils literal notranslate">PATH</code> to
<code class="docutils literal notranslate">/path/to/ninja/bin${pathListSep}$env{PATH}</code>, <code class="docutils literal notranslate">${pathListSep}</code> will
expand to the underlying operating system's character used for
concatenation in <code class="docutils literal notranslate">PATH</code>.
This is allowed in preset files specifying version <code class="docutils literal notranslate">5</code> or above.
</dd>
<dt><code class="docutils literal notranslate">$env{&lt;variable-name&gt;}</code></dt><dd>Environment variable with name <code class="docutils literal notranslate">&lt;variable-name&gt;</code>. The variable name may
not be an empty string. If the variable is defined in the <code class="docutils literal notranslate">environment</code>
field, that value is used instead of the value from the parent environment.
If the environment variable is not defined, this evaluates as an empty
string.
Note that while Windows environment variable names are case-insensitive,
variable names within a preset are still case-sensitive. This may lead to
unexpected results when using inconsistent casing. For best results, keep
the casing of environment variable names consistent.
</dd>
<dt><code class="docutils literal notranslate">$penv{&lt;variable-name&gt;}</code></dt><dd>Similar to <code class="docutils literal notranslate">$env{&lt;variable-name&gt;}</code>, except that the value only comes from
the parent environment, and never from the <code class="docutils literal notranslate">environment</code> field. This
allows you to prepend or append values to existing environment variables.
For example, setting <code class="docutils literal notranslate">PATH</code> to <code class="docutils literal notranslate">/path/to/ninja/bin:$penv{PATH}</code> will
prepend <code class="docutils literal notranslate">/path/to/ninja/bin</code> to the <code class="docutils literal notranslate">PATH</code> environment variable. This
is needed because <code class="docutils literal notranslate">$env{&lt;variable-name&gt;}</code> does not allow circular
references.
</dd>
<dt><code class="docutils literal notranslate">$vendor{&lt;macro-name&gt;}</code></dt><dd>An extension point for vendors to insert their own macros. CMake will not
be able to use presets which have a <code class="docutils literal notranslate">$vendor{&lt;macro-name&gt;}</code> macro, and
effectively ignores such presets. However, it will still be able to use
other presets from the same file.
CMake does not make any attempt to interpret <code class="docutils literal notranslate">$vendor{&lt;macro-name&gt;}</code>
macros. However, to avoid name collisions, IDE vendors should prefix
<code class="docutils literal notranslate">&lt;macro-name&gt;</code> with a very short (preferably &lt;= 4 characters) vendor
identifier prefix, followed by a <code class="docutils literal notranslate">.</code>, followed by the macro name. For
example, the Example IDE could have <code class="docutils literal notranslate">$vendor{xide.ideInstallDir}</code>.
