| <p>The executable is run in the optionally specified directory. The |
| executable can include arguments if it is double quoted, but it is |
| better to use the optional <code class="docutils literal"><span class="pre">ARGS</span></code> argument to specify arguments to the |
| program. This is because cmake will then be able to escape spaces in |
| the executable path. An optional argument <code class="docutils literal"><span class="pre">OUTPUT_VARIABLE</span></code> specifies a |
| variable in which to store the output. To capture the return value of |
| the execution, provide a <code class="docutils literal"><span class="pre">RETURN_VALUE</span></code>. If <code class="docutils literal"><span class="pre">OUTPUT_VARIABLE</span></code> is |
| specified, then no output will go to the stdout/stderr of the console |
| running cmake.</p> |
