| <p>In CMake 3.18 and lower a dependency on the evaluated target of the above |
| generator expressions would always be added. CMake 3.19 and above prefer |
| to not add this dependency. This policy provides compatibility for projects |
| that have not been updated to expect the new behavior. The policy setting |
| is recorded on each target when it is created, and decides whether generator |
| expressions referencing that target imply a dependency on it.</p> |
| <p>The <code class="docutils literal notranslate"><span class="pre">OLD</span></code> behavior for this policy is to add a dependency on the evaluated |
| target for the above generator expressions. The <code class="docutils literal notranslate"><span class="pre">NEW</span></code> behavior of |
| this policy is to not add a dependency on the evaluated target for the |
| above generator expressions.</p> |
| <p>This policy was introduced in CMake version 3.19. Unlike many policies, |
| CMake version 3.23.1 does <em>not</em> warn by default when this policy |
| is not set and simply uses <code class="docutils literal notranslate"><span class="pre">OLD</span></code> behavior. See documentation of the |
