| <p>Defines a group into which sources will be placed in project files. |
| This is intended to set up file tabs in Visual Studio. |
| The options are:</p> |
| <dl class="docutils"> |
| <dt><code class="docutils literal"><span class="pre">TREE</span></code></dt> |
| <dd>CMake will automatically detect, from <code class="docutils literal"><span class="pre"><src></span></code> files paths, source groups |
| it needs to create, to keep structure of source groups analogically to the |
| actual files and directories structure in the project. Paths of <code class="docutils literal"><span class="pre"><src></span></code> |
| files will be cut to be relative to <code class="docutils literal"><span class="pre"><root></span></code>.</dd> |
| <dt><code class="docutils literal"><span class="pre">PREFIX</span></code></dt> |
| <dd>Source group and files located directly in <code class="docutils literal"><span class="pre"><root></span></code> path, will be placed |
| in <code class="docutils literal"><span class="pre"><prefix></span></code> source groups.</dd> |
| <dt><code class="docutils literal"><span class="pre">FILES</span></code></dt> |
| <dd>Any source file specified explicitly will be placed in group |
| <code class="docutils literal"><span class="pre"><name></span></code>. Relative paths are interpreted with respect to the |
| current source directory.</dd> |
| <dt><code class="docutils literal"><span class="pre">REGULAR_EXPRESSION</span></code></dt> |
| <dd>Any source file whose name matches the regular expression will |
| be placed in group <code class="docutils literal"><span class="pre"><name></span></code>.</dd> |
| </dl> |
| <p>If a source file matches multiple groups, the <em>last</em> group that |
| explicitly lists the file with <code class="docutils literal"><span class="pre">FILES</span></code> will be favored, if any. |
| If no group explicitly lists the file, the <em>last</em> group whose |
| regular expression matches the file will be favored.</p> |
| <p>The <code class="docutils literal"><span class="pre"><name></span></code> of the group and <code class="docutils literal"><span class="pre"><prefix></span></code> argument may contain backslashes |
| to specify subgroups:</p> |
| <div class="highlight-cmake"><div class="highlight"><pre><span></span><span class="nb">source_group</span><span class="p">(</span><span class="s">outer\\inner</span> <span class="s">...</span><span class="p">)</span> |

| <p>For backwards compatibility, the short-hand signature</p> |
| <div class="highlight-cmake"><div class="highlight"><pre><span></span><span class="nb">source_group</span><span class="p">(</span><span class="s"><name></span> <span class="s"><regex></span><span class="p">)</span> |
