| If a path starts with a generator expression, it is expected to |
| evaluate to an absolute path. Not doing so is considered undefined behavior.</p> |
| <p>Paths that are for files generated by the build will be treated |
| as relative to the build directory of the target, if the path is not |
| already specified as an absolute path. Note that whether a file is seen as |
| generated may be affected by policy <span class="target" id="index-0-policy:CMP0118"></span><a class="reference internal" href="../policy/CMP0118.html#policy:CMP0118" title="CMP0118"><code class="xref cmake cmake-policy docutils literal notranslate"><span class="pre">CMP0118</span></code></a>.</p> |
| <p>If a path does not start with a generator expression, is not an |
| absolute path and is not a generated file, it will be treated as relative to |
| the location selected by the first of the following that matches:</p> |
| <ul class="simple"> |
| <li><p>If a file by the specified path exists relative to the target's source |
| directory, use that file.</p></li> |
| <li><p>If policy <span class="target" id="index-0-policy:CMP0115"></span><a class="reference internal" href="../policy/CMP0115.html#policy:CMP0115" title="CMP0115"><code class="xref cmake cmake-policy docutils literal notranslate"><span class="pre">CMP0115</span></code></a> is not set to <code class="docutils literal notranslate"><span class="pre">NEW</span></code>, try appending each |
| known source file extension to the path and check if that exists |
| relative to the target's source directory.</p></li> |
| <li><p>Repeat the above two steps, this time relative to the target's binary |
| directory instead.</p></li> |
| </ul> |
| <p>Note that the above decisions are made at generation time, not build time.</p> |
