| <p>The value is ignored on non-MSVC compilers but an unsupported value will |

| <p>The value may also be the empty string (<code class="docutils literal notranslate"><span class="pre">""</span></code>) in which case no runtime |
| library selection flag will be added explicitly by CMake. Note that with |
| <a class="reference internal" href="../manual/cmake-generators.7.html#visual-studio-generators"><span class="std std-ref">Visual Studio Generators</span></a> the native build system may choose to |

| <p>selects for the target <code class="docutils literal notranslate"><span class="pre">foo</span></code> a multi-threaded statically-linked runtime |

| <p>If this property is not set then CMake uses the default value |
