本文介绍如何在Xcode环境中使用CMake配置Qt项目。主要解决CMake启动后出现的Qt5_DIR-NOTFOUND错误。通过正确设置CMAKE_INSTALL_PREFIX为Qt安装目录，可以顺利进行配置和生成。

【Qt】【Xcode】【CMake】-Qt5_DIR-NOTFOUND的解决方法

希望用Xcode编译Qt的CMake项目。

【报错】：

CMake启动后，直接点击按钮：generate，会报错：

Qt5_DIR-NOTFOUND

【解决】：

1.在CMake中，设置如下：

CMAKE_INSTALL_PREFIX 设置为Mac上安装的Qt目录即可。

如：本人安装的Qt路径为：/Users/goodmao/Qt_all_version/Qt5.15.4/5.15.4

CMake启动后，设置如下图：

 2.点击configure，不再报错

3.点击generate，成功。

Add the installation prefix of “Qt5“ to CMAKE_PREFIX_PATH or set “Qt5_DIR“解决

编译VTK时Qt5_DIR-NOTFOUND的解决方法 在编译VTK时需要用到Qt，打开了Module_vtkGUISupportQt和Module_vtkViewsQt两个模块，用的是Qt5。CMake Configure的时候出现Qt5_DIR-NOTFOUND的错误。解决方法如下。 Qt5安装路径以我电脑的Qt5安装路径为例，在我电脑上Qt是安装在：E:\Toolkits\Qt\Qt5.

001. linux qt编译报错 清理项目，删掉debug文件夹，重新运行 查看*.pro文件是否正确 002. linux qt编写、使用动态库 使用时需要复制所有的.h文件 需要将动态库*.pro中包含的路径和lib添加至项目文件*.pro中 需要把所有用到的动态库放到/usr/lib中，或参考【007】手动配置动态库路径（推荐后者） 主程序*.pro文件需要添加所有动态库包含的 “QT += core gui” 003. linux tcp/ip监测连接状态 以心跳包、发送反馈等形式自主监测 0
【已解决】Cmake编译Qt项目出现Qt5_dir-NOTFOUND
OPM的博客

在使用Cmake导入项目源码后，点击configure的第一步配置阶段，会出现一些路径找不到的情况。这次的Qt项目就是这个问题。一般的第三方库找到源路径比较好找，Qt这里的子路径比较多。需要选择到安装目录下的如下子路径，例如我的版本是5.14.2，直接装在C盘，地址如下。这里主要参考了之前以为前辈的博客经验，第二种写入环境变量的处理办法还没有尝试。选择后再点击configure，Cmake已经找到了Qt相关内容。有兴趣的大佬可以看一下他的帖子。

在使用cmake构建工程时，找不到qt5。 方法一： 找到qt的安装目录然后选择，windows默认安装的路径一般为 C:\Qt\Qt5.5.1\5.5\msvc2012\lib\cmake\Qt5 msvc目录有可能也是gcc_64，视安装为准。 方法二： 编辑系统环境变量，新建一个名为Qt5_DIR环境变量，变量值为上述目录 C:\Qt\Qt5.5.1\5.5\msvc2012\lib\cmake\Qt5 ...
