<h1 id="Cmake-文件组织"><a href="#Cmake-文件组织" class="headerlink" title="Cmake 文件组织"></a>Cmake 文件组织</h1><p>在cmake中，添加源文件后，如果用vs编译，打开工程，文件会比较乱全都摆在一起，这是需要使用souce_group()将文件分组，下面是代码示例：</p>
<figure class="highlight cmake"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br><span class="line">9</span><br></pre></td><td class="code"><pre><span class="line"><span class="keyword">foreach</span>(<span class="keyword">FILE</span> <span class="variable">${all_files}</span>)</span><br><span class="line"> <span class="comment">#convert source file to absolute</span></span><br><span class="line"> <span class="keyword">get_filename_component</span>(ABSOLUTE_PATH <span class="string">"${FILE}"</span> ABSOLUTE)</span><br><span class="line"> <span class="comment"># Get the directory of the absolute source file</span></span><br><span class="line"> <span class="keyword">get_filename_component</span>(PARENT_DIR <span class="string">"${ABSOLUTE_PATH}"</span> DIRECTORY)</span><br><span class="line"> <span class="comment"># Remove common directory prefix to make the group</span></span><br><span class="line"> <span class="keyword">string</span>(REPLACE <span class="string">"${CMAKE_CURRENT_SOURCE_DIR}"</span> <span class="string">""</span> GROUP <span class="string">"${PARENT_DIR}"</span>)</span><br><span class="line"> <span class="keyword">source_group</span>(<span class="string">"${GROUP}"</span> FILES <span class="string">"${FILE}"</span>)</span><br><span class="line"><span class="keyword">endforeach</span>()</span><br></pre></td></tr></table></figure>
<p>这段代码将项目源码按照原有的文件夹分类，效果如下图所示<img src="images/xiangmuzuzhi.png" alt="文件组织图片"></p>
<p>此外还可以将cmake项目分组，如外部依赖分到“dependencies”下。<br>首先需要使用命令</p>
<figure class="highlight cmake"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line"><span class="keyword">set_property</span>(GLOBAL PROPERTY USE_FOLDERS <span class="keyword">ON</span>)</span><br></pre></td></tr></table></figure>
<p>开启folder功能，然后将特定子项目分组</p>
<figure class="highlight cmake"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br></pre></td><td class="code"><pre><span class="line"><span class="keyword">add_subdirectory</span>(<span class="variable">${CMAKE_CURRENT_SOURCE_DIR}</span>/MeshMatching/extern/ANN)</span><br><span class="line"><span class="keyword">set_property</span>(<span class="keyword">TARGET</span> ANN PROPERTY FOLDER <span class="string">"dependencies"</span>)</span><br><span class="line"><span class="keyword">add_subdirectory</span>(<span class="variable">${CMAKE_CURRENT_SOURCE_DIR}</span>/Simplification)</span><br><span class="line"><span class="keyword">set_property</span>(<span class="keyword">TARGET</span> complex_simplification PROPERTY FOLDER <span class="string">"dependencies"</span>)</span><br></pre></td></tr></table></figure>
<p>结果如下图所示：<br><img src="images/%E5%88%86%E7%BB%84.png" alt="文件组织图片"></p>

<h2 id="copy优化"><a href="#copy优化" class="headerlink" title="copy优化"></a>copy优化</h2><p>在c++中，有许多地方都会隐式的进行copy操作，对于一般的内置类型的变量，这种copy的开销可以忽略，但是挡在操作一些类对象或是结构体时，除非必要，不然应避免多余的copy操作，比较好的习惯是，在传参是使用<code>&</code>引用符号。这里记录一下关于操作vector时需要注意的细节。</p>
