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 main files,
|
|
``CMakePresets.json`` and ``CMakeUserPresets.json``, that allow users to
|
|
specify common configure options and share them with others. CMake also
|
|
supports files included with the ``include`` field.
|
|
|
|
``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 specify project-wide build details, while
|
|
``CMakeUserPresets.json`` is meant for developers to specify their own local
|
|
build details.
|
|
|
|
``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.
|
|
The supported versions are ``1``, ``2``, ``3``, and ``4``.
|
|
|
|
``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.
|
|
|
|
``include``
|
|
|
|
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 ``4`` or above.
|
|
See `Includes`_ for discussion of the constraints on included files.
|
|
|
|
``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.
|
|
This is allowed in preset files specifying version ``1`` or above.
|
|
|
|
``buildPresets``
|
|
|
|
An optional array of `Build Preset`_ objects.
|
|
This is allowed in preset files specifying version ``2`` or above.
|
|
|
|
``testPresets``
|
|
|
|
An optional array of `Test Preset`_ objects.
|
|
This is allowed in preset files specifying version ``2`` or above.
|
|
|
|
Includes
|
|
^^^^^^^^
|
|
|
|
``CMakePresets.json`` and ``CMakeUserPresets.json`` can include other files
|
|
with the ``include`` field in file version ``4`` and later. Files included
|
|
by these files can also include other files. If ``CMakePresets.json`` and
|
|
``CMakeUserPresets.json`` are both present, ``CMakeUserPresets.json``
|
|
implicitly includes ``CMakePresets.json``, even with no ``include`` 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 ``a.json`` includes
|
|
``b.json``, ``b.json`` cannot include ``a.json``. However, a file may be
|
|
included multiple times from the same file or from different files.
|
|
|
|
Files directly or indirectly included from ``CMakePresets.json`` should be
|
|
guaranteed to be provided by the project. ``CMakeUserPresets.json`` may
|
|
include files from anywhere.
|
|
|
|
Configure Preset
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
Each entry of the ``configurePresets`` array is a JSON object
|
|
that may contain the following fields:
|
|
|
|
``name``
|
|
|
|
A required string representing the machine-friendly name of the preset.
|
|
This identifier is used in the :ref:`cmake --preset <CMake Options>` option.
|
|
There must not be two configure presets in the union of ``CMakePresets.json``
|
|
and ``CMakeUserPresets.json`` in the same directory with the same name.
|
|
However, a configure preset may have the same name as a build or test preset.
|
|
|
|
``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. 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 ``inherits``
|
|
presets by default (except ``name``, ``hidden``, ``inherits``,
|
|
``description``, and ``displayName``), 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.
|
|
|
|
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 ``CMakePresets.json`` may not inherit from presets in
|
|
``CMakeUserPresets.json``.
|
|
|
|
``condition``
|
|
|
|
An optional `Condition`_ object. This is allowed in preset files specifying
|
|
version ``3`` or above.
|
|
|
|
``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``). In version ``3``
|
|
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 ``-G``
|
|
argument, you cannot include the platform name in the generator name. Use
|
|
the ``architecture`` field instead.
|
|
|
|
``architecture``, ``toolset``
|
|
|
|
Optional fields representing the platform and toolset, respectively, for
|
|
generators that support them. Each may be either a string or an object
|
|
with the following fields:
|
|
|
|
``value``
|
|
|
|
An optional string representing the value.
|
|
|
|
``strategy``
|
|
|
|
An optional string telling CMake how to handle the ``architecture`` or
|
|
``toolset`` field. Valid values are:
|
|
|
|
``"set"``
|
|
|
|
Set the respective value. This will result in an error for generators
|
|
that do not support the respective field.
|
|
|
|
``"external"``
|
|
|
|
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
|
|
``architecture`` and ``toolset`` fields. In that case, CMake will
|
|
ignore the field, but the IDE can use them to set up the environment
|
|
before invoking CMake.
|
|
|
|
``toolchainFile``
|
|
|
|
An optional string representing the path to the toolchain file.
|
|
This field supports `macro expansion`_. 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
|
|
:variable:`CMAKE_TOOLCHAIN_FILE` value. It is allowed in preset files
|
|
specifying version ``3`` or above.
|
|
|
|
``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``). In version ``3`` or above, this field may be
|
|
omitted.
|
|
|
|
``installDir``
|
|
|
|
An optional string representing the path to the installation directory.
|
|
This field supports `macro expansion`_. If a relative path is specified,
|
|
it is calculated relative to the source directory. This is allowed in
|
|
preset files specifying version ``3`` or above.
|
|
|
|
``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 boolean
|
|
(which is equivalent to a value of ``"TRUE"`` or ``"FALSE"`` and a type
|
|
of ``BOOL``), 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 or boolean representing the value of the variable.
|
|
A boolean is equivalent to ``"TRUE"`` or ``"FALSE"``. 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.
|
|
|
|
Build Preset
|
|
^^^^^^^^^^^^
|
|
|
|
Each entry of the ``buildPresets`` array is a JSON object
|
|
that may contain the following fields:
|
|
|
|
``name``
|
|
|
|
A required string representing the machine-friendly name of the preset.
|
|
This identifier is used in the
|
|
:ref:`cmake --build --preset <Build Tool Mode>` option.
|
|
There must not be two build presets in the union of ``CMakePresets.json``
|
|
and ``CMakeUserPresets.json`` in the same directory with the same name.
|
|
However, a build preset may have the same name as a configure or test preset.
|
|
|
|
``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
|
|
and does not have to have a valid ``configurePreset``, 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. 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
|
|
``inherits`` presets by default (except ``name``, ``hidden``,
|
|
``inherits``, ``description``, and ``displayName``), 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.
|
|
|
|
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 ``CMakePresets.json`` may not inherit from presets in
|
|
``CMakeUserPresets.json``.
|
|
|
|
``condition``
|
|
|
|
An optional `Condition`_ object. This is allowed in preset files specifying
|
|
version ``3`` or above.
|
|
|
|
``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.
|
|
|
|
``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.
|
|
|
|
.. note::
|
|
|
|
For a CMake project using ExternalProject with a configuration preset
|
|
having environment variables needed in the ExternalProject, use a build
|
|
preset that inherits that configuration preset or the ExternalProject
|
|
will not have the environment variables set in the configuration preset.
|
|
Example: suppose the host defaults to one compiler (say Clang)
|
|
and the user wishes to use another compiler (say GCC). Set configuration
|
|
preset environment variables ``CC`` and ``CXX`` and use a build preset
|
|
that inherits that configuration preset. Otherwise the ExternalProject
|
|
may use a different (system default) compiler than the top-level CMake
|
|
project.
|
|
|
|
``configurePreset``
|
|
|
|
An optional string specifying the name of a configure preset to
|
|
associate with this build preset. If ``configurePreset`` 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 the build will take place in the same ``binaryDir`` that the
|
|
configuration did.
|
|
|
|
``inheritConfigureEnvironment``
|
|
|
|
An optional boolean that defaults to true. If true, the environment
|
|
variables from the associated configure preset are inherited after all
|
|
inherited build preset environments, but before environment variables
|
|
explicitly specified in this build preset.
|
|
|
|
``jobs``
|
|
|
|
An optional integer. Equivalent to passing ``--parallel`` or ``-j`` on
|
|
the command line.
|
|
|
|
``targets``
|
|
|
|
An optional string or array of strings. Equivalent to passing
|
|
``--target`` or ``-t`` on the command line. Vendors may ignore the
|
|
targets property or hide build presets that explicitly specify targets.
|
|
This field supports macro expansion.
|
|
|
|
``configuration``
|
|
|
|
An optional string. Equivalent to passing ``--config`` on the command
|
|
line.
|
|
|
|
``cleanFirst``
|
|
|
|
An optional bool. If true, equivalent to passing ``--clean-first`` on
|
|
the command line.
|
|
|
|
``resolvePackageReferences``
|
|
|
|
An optional string that specifies the package resolve mode. This is
|
|
allowed in preset files specifying version ``4`` or above.
|
|
|
|
Package references are used to define dependencies to packages from
|
|
external package managers. Currently only NuGet in combination with the
|
|
Visual Studio generator is supported. If there are no targets that define
|
|
package references, this option does nothing. Valid values are:
|
|
|
|
``on``
|
|
|
|
Causes package references to be resolved before attempting a build.
|
|
|
|
``off``
|
|
|
|
Package references will not be resolved. Note that this may cause
|
|
errors in some build environments, such as .NET SDK style projects.
|
|
|
|
``only``
|
|
|
|
Only resolve package references, but do not perform a build.
|
|
|
|
.. note::
|
|
|
|
The command line parameter ``--resolve-package-references`` will take
|
|
priority over this setting. If the command line parameter is not provided
|
|
and this setting is not specified, an environment-specific cache variable
|
|
will be evaluated to decide, if package restoration should be performed.
|
|
|
|
When using the Visual Studio generator, package references are defined
|
|
using the :prop_tgt:`VS_PACKAGE_REFERENCES` property. Package references
|
|
are restored using NuGet. It can be disabled by setting the
|
|
``CMAKE_VS_NUGET_PACKAGE_RESTORE`` variable to ``OFF``. This can also be
|
|
done from within a configure preset.
|
|
|
|
``verbose``
|
|
|
|
An optional bool. If true, equivalent to passing ``--verbose`` on the
|
|
command line.
|
|
|
|
``nativeToolOptions``
|
|
|
|
An optional array of strings. Equivalent to passing options after ``--``
|
|
on the command line. The array values support macro expansion.
|
|
|
|
Test Preset
|
|
^^^^^^^^^^^
|
|
|
|
Each entry of the ``testPresets`` array is a JSON object
|
|
that may contain the following fields:
|
|
|
|
``name``
|
|
|
|
A required string representing the machine-friendly name of the preset.
|
|
This identifier is used in the :ref:`ctest --preset <CTest Options>` option.
|
|
There must not be two test presets in the union of ``CMakePresets.json``
|
|
and ``CMakeUserPresets.json`` in the same directory with the same name.
|
|
However, a test preset may have the same name as a configure or build preset.
|
|
|
|
``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
|
|
and does not have to have a valid ``configurePreset``, 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. 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
|
|
``inherits`` presets by default (except ``name``, ``hidden``,
|
|
``inherits``, ``description``, and ``displayName``), 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.
|
|
|
|
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 ``CMakePresets.json`` may not inherit from presets in
|
|
``CMakeUserPresets.json``.
|
|
|
|
``condition``
|
|
|
|
An optional `Condition`_ object. This is allowed in preset files specifying
|
|
version ``3`` or above.
|
|
|
|
``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.
|
|
|
|
``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.
|
|
|
|
``configurePreset``
|
|
|
|
An optional string specifying the name of a configure preset to
|
|
associate with this test preset. If ``configurePreset`` 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 tests will run in the same ``binaryDir`` that the
|
|
configuration did and build did.
|
|
|
|
``inheritConfigureEnvironment``
|
|
|
|
An optional boolean that defaults to true. If true, the environment
|
|
variables from the associated configure preset are inherited after all
|
|
inherited test preset environments, but before environment variables
|
|
explicitly specified in this test preset.
|
|
|
|
``configuration``
|
|
|
|
An optional string. Equivalent to passing ``--build-config`` on the
|
|
command line.
|
|
|
|
``overwriteConfigurationFile``
|
|
|
|
An optional array of configuration options to overwrite options
|
|
specified in the CTest configuration file. Equivalent to passing
|
|
``--overwrite`` for each value in the array. The array values
|
|
support macro expansion.
|
|
|
|
``output``
|
|
|
|
An optional object specifying output options. The object may contain the
|
|
following fields.
|
|
|
|
``shortProgress``
|
|
|
|
An optional bool. If true, equivalent to passing ``--progress`` on the
|
|
command line.
|
|
|
|
``verbosity``
|
|
|
|
An optional string specifying verbosity level. Must be one of the
|
|
following:
|
|
|
|
``default``
|
|
|
|
Equivalent to passing no verbosity flags on the command line.
|
|
|
|
``verbose``
|
|
|
|
Equivalent to passing ``--verbose`` on the command line.
|
|
|
|
``extra``
|
|
|
|
Equivalent to passing ``--extra-verbose`` on the command line.
|
|
|

|
|
|
An optional bool. If true, equivalent to passing ``--quiet`` on the
|
|
command line.
|
|
|
|
``outputLogFile``
|
|
|
|
An optional string specifying a path to a log file. Equivalent to
|
|
passing ``--output-log`` on the command line. This field supports
|
|
macro expansion.

``labelSummary``
|
|
|
|
An optional bool. If false, equivalent to passing
|
|
``--no-label-summary`` on the command line.

An optional bool. If false, equivalent to passing
|
|
``--no-subproject-summary`` on the command line.
|
|
|
|
``maxPassedTestOutputSize``

|
An optional integer specifying the maximum output for passed tests in
|
|
bytes. Equivalent to passing ``--test-output-size-passed`` on the
|
|
command line.

|
|
|
|
An optional integer specifying the maximum output for failed tests in
|

An optional object specifying tests to include by test index. The
|
|
object may contain the following fields. Can also be an optional

supports macro expansion.
|
|

|
|
|
|
Condition
|
|
^^^^^^^^^
|
|
|
|
The ``condition`` field of a preset, allowed in preset files specifying version
|
|
``3`` or above, is used to determine whether or not the preset is enabled. For
|
|
example, this can be used to disable a preset on platforms other than Windows.
|
|
``condition`` may be either a boolean, ``null``, or an object. If it is a
|
|
boolean, the boolean indicates whether the preset is enabled or disabled. If it
|
|
is ``null``, the preset is enabled, but the ``null`` condition is not inherited
|
|
by any presets that may inherit from the preset. Sub-conditions (for example in
|
|
a ``not``, ``anyOf``, or ``allOf`` condition) may not be ``null``. If it is an
|
|
object, it has the following fields:
|
|
|
|
``type``
|
|
|
|
A required string with one of the following values:
|
|
|
|
``"const"``
|
|
|
|
Indicates that the condition is constant. This is equivalent to using a
|
|
boolean in place of the object. The condition object will have the
|
|
following additional fields:
|
|
|
|
``value``
|
|
|
|
A required boolean which provides a constant value for the condition's
|
|
evaluation.
|
|
|
|
``"equals"``
|
|
|
|
``"notEquals"``
|
|
|
|
Indicates that the condition compares two strings to see if they are equal
|
|
(or not equal). The condition object will have the following additional
|
|
fields:
|
|
|
|
``lhs``
|
|
|
|
First string to compare. This field supports macro expansion.
|
|
|
|
``rhs``
|
|
|
|
Second string to compare. This field supports macro expansion.
|
|
|
|
``"inList"``
|
|
|
|
``"notInList"``
|
|
|
|
Indicates that the condition searches for a string in a list of strings.
|
|
The condition object will have the following additional fields:
|
|
|
|
``string``
|
|
|
|
A required string to search for. This field supports macro expansion.
|
|
|
|
``list``
|
|
|
|
A required list of strings to search. This field supports macro
|
|
expansion, and uses short-circuit evaluation.
|
|
|
|
``"matches"``
|
|
|
|
``"notMatches"``
|
|
|
|
Indicates that the condition searches for a regular expression in a string.
|
|
The condition object will have the following additional fields:
|
|
|
|
``string``
|
|
|
|
A required string to search. This field supports macro expansion.
|
|
|
|
``regex``
|
|
|
|
A required regular expression to search for. This field supports macro
|
|
expansion.
|
|
|
|
``"anyOf"``
|
|
|
|
``"allOf"``
|
|
|
|
Indicates that the condition is an aggregation of zero or more nested
|
|
conditions. The condition object will have the following additional fields:
|
|
|
|
``conditions``
|
|
|
|
A required array of condition objects. These conditions use short-circuit
|
|
evaluation.
|
|
|
|
``"not"``
|
|
|
|
Indicates that the condition is an inversion of another condition. The
|
|
condition object will have the following additional fields:
|
|
|
|
``condition``
|
|
|
|
A required condition object.
|
|
|
|
Macro Expansion
|
|
^^^^^^^^^^^^^^^
|
|
|
|
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:
|
|
|
|
``${sourceDir}``
|
|
|
|
Path to the project source directory (i.e. the same as
|
|
:variable:`CMAKE_SOURCE_DIR`).
|
|
|
|
``${sourceParentDir}``
|
|
|
|
Path to the project source directory's parent directory.
|
|
|
|
``${sourceDirName}``
|
|
|
|
The last filename component of ``${sourceDir}``. For example, if
|
|
``${sourceDir}`` is ``/path/to/source``, this would be ``source``.
|
|
|
|
``${presetName}``
|
|
|
|
Name specified in the preset's ``name`` field.
|
|
|
|
``${generator}``
|
|
|
|
Generator specified in the preset's ``generator`` field. For build and
|
|
test presets, this will evaluate to the generator specified by
|
|
``configurePreset``.
|
|
|
|
``${hostSystemName}``
|
|
|
|
The name of the host operating system. Contains the same value as
|
|
:variable:`CMAKE_HOST_SYSTEM_NAME`. This is allowed in preset files
|
|
specifying version ``3`` or above.
|
|
|
|
``${fileDir}``
|
|
|
|
Path to the directory containing the preset file which contains the macro.
|
|
This is allowed in preset files specifying version ``4`` or above.
|
|
|
|
``${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}``.
|
