Configure Preset
|
||||
^^^^^^^^^^^^^^^^
|
||||
|
||||
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``
|
||||
``name``
|
||||
|
||||
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.
|

A required string representing the machine-friendly name of the preset.
|

``CMakeUserPresets.json`` in the same directory with the same name.
|
||||
|
||||
``inherits``
|
||||
``hidden``
|
||||
|
||||
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 ``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. Presets in ``CMakePresets.json`` may not inherit from presets
|
||||
in ``CMakeUserPresets.json``.

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.
|

containing one string.
|
||||
|

``generator``
|
||||
``description``
|
||||
|
||||
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``).
|
||||
An optional string with a human-friendly description of the preset.
|
||||
|
||||
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.
|

``generator``
|

``architecture``
|

``toolset``
|

|
||||
``value``
|
||||
``architecture``, ``toolset``
|
||||
|
||||
An optional string representing the value.
|
||||
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:
|
||||
|
||||
``strategy``
|
||||
``value``
|
||||
|
||||
An optional string telling CMake how to handle the ``architecture`` or
|
||||
``toolset`` field. Valid values are:
|
||||
An optional string representing the value.
|
||||
|
||||
``"set"``
|
||||
``strategy``
|
||||
|
||||
Set the respective value. This will result in an error for generators
|
||||
that do not support the respective field.
|
||||
An optional string telling CMake how to handle the ``architecture`` or
|
||||
``toolset`` field. Valid values are:
|
||||
|
||||
``"external"``
|
||||
``"set"``
|
||||
|
||||
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.
|

Set the respective value. This will result in an error for generators
|
||||
that do not support the respective field.
|
||||
|
||||
``binaryDir``
|
||||
``"external"``
|
||||
|
||||
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``
|
||||
``binaryDir``
|
||||
|
||||
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.
|
||||
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``).
|
||||
|
||||
``cacheVariables``
|
||||
``cmakeExecutable``
|
||||
|
||||
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
|

may not be an empty string), and the value is either ``null``, a boolean
|

``value``
|

``type``
|
||||
|

A required string or boolean representing the value of the variable.
|

A boolean is equivalent to ``"TRUE"`` or ``"FALSE"``. This field
|
||||
supports macro expansion.
|
||||
An optional string representing the type of the variable.
|
||||
|
||||
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.
|
||||
``value``
|
||||
|
||||
``environment``
|
||||
A required string or boolean representing the value of the variable.
|

A boolean is equivalent to ``"TRUE"`` or ``"FALSE"``. This field
|
||||
supports `macro expansion`_.
|
||||
|
||||
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}``.)

|
||||
|
||||
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``.
|
||||
``find``
|
||||
|
||||
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.
|

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 ``${presetName}``, and the
|
||||
``Derived`` preset inherits from ``Base``, ``PRESET_NAME`` will be set to
|
||||
``Derived``.
|
||||
|
||||
Path to the project source directory.
|
||||
It is an error to not put a closing brace at the end of a macro name. For
|
||||
example, ``${sourceDir`` is invalid. A dollar sign (``$``) followed by
|
||||
anything other than a left curly brace (``{``) with a possible namespace is
|
||||
interpreted as a literal dollar sign.
|
||||
|
||||
``${sourceParentDir}``
|
||||
Recognized macros include:
|
||||
|
||||
Path to the project source directory's parent directory.
|
||||
``${sourceDir}``
|
||||
|
||||
``${sourceDirName}``
|
||||
Path to the project source directory.
|
||||
|
||||
The last filename component of ``${sourceDir}``. For example, if
|
||||
``${sourceDir}`` is ``/path/to/source``, this would be ``source``.
|
||||
``${sourceParentDir}``
|
||||
|
||||
``${presetName}``
|
||||
Path to the project source directory's parent directory.
|
||||
|
||||
Name specified in the preset's ``name`` field.
|
||||
``${sourceDirName}``
|
||||
|
||||
``${generator}``
|
||||
The last filename component of ``${sourceDir}``. For example, if
|
||||
``${sourceDir}`` is ``/path/to/source``, this would be ``source``.
|
||||
|
||||
Generator specified in the preset's ``generator`` field.
|
||||
``${presetName}``
|
||||
|
||||
``${dollar}``
|
||||
Name specified in the preset's ``name`` field.
|
||||
|
||||
A literal dollar sign (``$``).
|
||||
``${generator}``
|
||||
|
||||
``$env{<variable-name>}``
|
||||
Generator specified in the preset's ``generator`` field.
|
||||
|
||||
Environment variable with name ``<variable-name>``. The variable name may
|
||||
not be an empty string. If the variable is defined in the ``environment``
|
||||
field, that value is used instead of the value from the parent environment.
|
||||
If the environment variable is not defined, this evaluates as an empty
|
||||
string.
|
||||
``${dollar}``
|
||||
|
||||
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.
|
||||
A literal dollar sign (``$``).
|
||||
|
||||
``$penv{<variable-name>}``
|
||||
``$env{<variable-name>}``
|
||||
|
||||
Similar to ``$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.
|
||||
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.
|
||||
|
||||
``$vendor{<macro-name>}``
|
||||
Note that while Windows environment variable names are case-insensitive,
|
||||
variable names within a preset are still case-sensitive. This may lead to
|
||||
unexpected results when using inconsistent casing. For best results, keep
|
||||
the casing of environment variable names consistent.
|
||||
|
||||
An extension point for vendors to insert their own macros. CMake will not
|
||||
be able to use presets which have a ``$vendor{<macro-name>}`` macro, and
|
||||
effectively ignores such presets. However, it will still be able to use
|
||||
other presets from the same file.
|
||||
``$penv{<variable-name>}``
|
||||
|
||||
CMake does not make any attempt to interpret ``$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}``.
