optionΒΆ
Provide an option that the user can optionally select.
option(<variable> "<help_text>" [value])
Provides an option for the user to select as ON
or OFF
.
If no initial <value>
is provided, OFF
is used.
If <variable>
is already set as a normal or cache variable,
then the command does nothing (see policy CMP0077
).
If you have options that depend on the values of other options, see
the module help for CMakeDependentOption
.
