<p>Specify the location or name of the macOS platform SDK to be used. | |
CMake uses this value to compute the value of the <code class="docutils literal notranslate"><span class="pre">-isysroot</span></code> flag | |
or equivalent and to help the <code class="docutils literal notranslate"><span class="pre">find_*</span></code> commands locate files in | |
the SDK.</p> | |
<p>If not set explicitly the value is initialized by the <code class="docutils literal notranslate"><span class="pre">SDKROOT</span></code> | |
environment variable, if set, and otherwise computed based on the | |
<span class="target" id="index-0-variable:CMAKE_OSX_DEPLOYMENT_TARGET"></span><a class="reference internal" href="CMAKE_OSX_DEPLOYMENT_TARGET.html#variable:CMAKE_OSX_DEPLOYMENT_TARGET" title="CMAKE_OSX_DEPLOYMENT_TARGET"><code class="xref cmake cmake-variable docutils literal notranslate"><span class="pre">CMAKE_OSX_DEPLOYMENT_TARGET</span></code></a> or the host platform.</p> | |

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> | |
