| ------- |
| |
| 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. |
| |
| This policy was introduced in CMake version 3.0. |
| CMake version |release| warns when the policy is not set and uses |
| OLD behavior. Use the cmake_policy command to set it to OLD or |
| NEW explicitly. |
