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.
