|
The :command:`project` command manages ``VERSION`` variables.
|
|
|
|
CMake version 3.0 introduced the ``VERSION`` option of the :command:`project`
|
|
command to specify a project version as well as the name. In order to keep
|
|
:variable:`PROJECT_VERSION` and related variables consistent with variable
|
|
:variable:`PROJECT_NAME` it is necessary to set the ``VERSION`` variables
|
|
to the empty string when no ``VERSION`` is given to :command:`project`.
|
|
However, this can change behavior for existing projects that set ``VERSION``
|
|
variables themselves since :command:`project` may now clear them.
|
|
This policy controls the behavior for compatibility with such projects.
|
|
|
|
The ``OLD`` behavior for this policy is to leave ``VERSION`` variables untouched.
|
|
The ``NEW`` behavior for this policy is to set ``VERSION`` as documented by the
|
|
:command:`project` command.
