| <p>CMake 3.10 and newer define that relative paths given to <code class="docutils literal notranslate"><span class="pre">INPUT</span></code> and |
| <code class="docutils literal notranslate"><span class="pre">OUTPUT</span></code> arguments of <code class="docutils literal notranslate"><span class="pre">file(GENERATE)</span></code> are interpreted relative to the |
| current source and binary directories, respectively. CMake 3.9 and lower did |
| not define any behavior for relative paths but did not diagnose them either |
| and accidentally treated them relative to the process working directory. |
| Policy <code class="docutils literal notranslate"><span class="pre">CMP0070</span></code> provides compatibility with projects that used the old |
| undefined behavior.</p> |
| <p>This policy affects behavior of relative paths given to <code class="docutils literal notranslate"><span class="pre">file(GENERATE)</span></code>. |
| The <code class="docutils literal notranslate"><span class="pre">OLD</span></code> behavior for this policy is to treat the paths relative to the |
| working directory of CMake. The <code class="docutils literal notranslate"><span class="pre">NEW</span></code> behavior for this policy is to |
| interpret relative paths with respect to the current source or binary |
| directory of the caller.</p> |
| <p>This policy was introduced in CMake version 3.10. 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. |
