option
|
|
------
|
|
|
|
Provide a boolean option that the user can optionally select.
|
|
|
|
.. code-block:: cmake
|
|
|
|
option(<variable> "<help_text>" [value])
|
|
|
|
If no initial ``<value>`` is provided, boolean ``OFF`` is the default value.
|
|
If ``<variable>`` is already set as a normal or cache variable,
|
|
then the command does nothing (see policy :policy:`CMP0077`).
|
|
|
|
For options that depend on the values of other options, see
|
|
the module help for :module:`CMakeDependentOption`.
|
|
|
|
In CMake project mode, a boolean cache variable is created with the option
|
|
value. In CMake script mode, a boolean variable is set with the option value.
