| <p>The CUDA/C++ standard whose features are requested to build this target.</p> |
| <p>This property specifies the CUDA/C++ standard whose features are requested |
| to build this target. For some compilers, this results in adding a |
| flag such as <code class="docutils literal notranslate"><span class="pre">-std=gnu++11</span></code> to the compile line.</p> |
| <p>Supported values are:</p> |
| <dl> |
| <dt><code class="docutils literal notranslate"><span class="pre">98</span></code></dt><dd><p>CUDA C++98. Note that this maps to the same as <code class="docutils literal notranslate"><span class="pre">03</span></code> internally.</p> |
| </dd> |

| <p>If the value requested does not result in a compile flag being added for |

| </pre></div> |
| </div> |
| <p>with a compiler which does not support <code class="docutils literal notranslate"><span class="pre">-std=gnu++11</span></code> or an equivalent |
| flag will not result in an error or warning, but will instead add the |
| <code class="docutils literal notranslate"><span class="pre">-std=gnu++03</span></code> flag if supported. This "decay" behavior may be controlled |
| with the <span class="target" id="index-0-prop_tgt:CUDA_STANDARD_REQUIRED"></span><a class="reference internal" href="CUDA_STANDARD_REQUIRED.html#prop_tgt:CUDA_STANDARD_REQUIRED" title="CUDA_STANDARD_REQUIRED"><code class="xref cmake cmake-prop_tgt docutils literal notranslate"><span class="pre">CUDA_STANDARD_REQUIRED</span></code></a> target property. |
