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 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
.
