| <p>Adds definitions to the compiler command line for targets in the current |
| directory and below (whether added before or after this command is invoked). |
| This command can be used to add any flags, but it is intended to add |
| preprocessor definitions (see the <span class="target" id="index-0-command:add_compile_options"></span><a class="reference internal" href="add_compile_options.html#command:add_compile_options" title="add_compile_options"><code class="xref cmake cmake-command docutils literal"><span class="pre">add_compile_options()</span></code></a> command |

| backwards compatibility. See documentation of the |
