| <p>Specify the minimum version of the target platform (e.g. macOS or iOS) |
| on which the target binaries are to be deployed. CMake uses this |
| variable value for the <code class="docutils literal notranslate"><span class="pre">-mmacosx-version-min</span></code> flag or their respective |
| target platform equivalents. For older Xcode versions that shipped |
| multiple macOS SDKs this variable also helps to choose the SDK in case |

| <p>If not set explicitly the value is initialized by the |
| <code class="docutils literal notranslate"><span class="pre">MACOSX_DEPLOYMENT_TARGET</span></code> environment variable, if set, |
| and otherwise computed based on the host platform.</p> |
| <p>The value of this variable should be set prior to the first |

| because it may influence configuration of the toolchain and flags. |
| It is intended to be set locally by the user creating a build tree. |
| This variable should be set as a <code class="docutils literal notranslate"><span class="pre">CACHE</span></code> entry (or else CMake may |
| remove it while initializing a cache entry of the same name).</p> |
| <p>Despite the <code class="docutils literal notranslate"><span class="pre">OSX</span></code> part in the variable name(s) they apply also to |
| other SDKs than macOS like iOS, tvOS, or watchOS.</p> |
| <p>This variable is ignored on platforms other than Apple.</p> |
