| <p>CMake >= 3.0 prefer that this command never be called. |
| The <code class="docutils literal notranslate"><span class="pre">OLD</span></code> behavior for this policy is to allow the command to be called. |
| The <code class="docutils literal notranslate"><span class="pre">NEW</span></code> behavior for this policy is to issue a <code class="docutils literal notranslate"><span class="pre">FATAL_ERROR</span></code> when the |
| command is called.</p> |
| <p>This policy was introduced in CMake version 3.0. |
| CMake version 3.23.1 warns when the policy is not set and uses |
| <code class="docutils literal notranslate"><span class="pre">OLD</span></code> behavior.
