sudo install ninja /usr/local/bin/

根据提供的引用内容，命令"sudo install ninja /usr/local/bin/"是错误的，正确的命令应该是"sudo cp ninja /usr/local/bin/"。这个命令的作用是将ninja可执行文件复制到/usr/local/bin/目录下，使得ninja可以在任何位置被调用执行。需要注意的是，如果/usr/local/bin/目录不存在，需要先创建该目录再执行复制命令。

这个错误表明CMake无法使用指定的C++编译器进行编译。出现这种情况可能有几种原因，我将提供一些可能的解决方案：

1. 确认C++编译器已正确安装：根据错误消息，您正在尝试使用`/usr/local/bin/g++-13`作为C++编译器。请确保您已经正确安装了该版本的GNU C++编译器。您可以在终端中运行以下命令来验证：

   g++-13 --version

如果没有安装或找不到该版本的g++，您可能需要安装它。

2. 更新Xcode Command Line Tools：错误消息中显示了`/Library/Developer/CommandLineTools/SDKs/MacOSX13.3.sdk`，这可能意味着您的Command Line Tools版本不兼容。您可以尝试更新Command Line Tools来解决此问题。在终端中运行以下命令：

   sudo rm -rf /Library/Developer/CommandLineTools
   sudo xcode-select --install

这将删除旧的Command Line Tools并安装最新版本。

3. 检查CMakeLists.txt文件：请确保您的CMakeLists.txt文件中的项目设置正确。特别是，请检查`project`命令是否正确设置了项目名称和所需的C++标准。

这些是常见的解决方案，您可以尝试进行修复。如果问题仍然存在，请提供更多的上下文信息，以便我能够更好地帮助您。

按照你说的做，为什么会报错如下：czj@czj-virtual-machine:~/build$ cmake .. -G Ninja CMake Warning (dev) in CMakeLists.txt: No project() command is present. The top-level CMakeLists.txt file must contain a literal, direct call to the project() command. Add a line of code such as project(ProjectName) near the top of the file, but after cmake_minimum_required(). CMake is pretending there is a "project(Project)" command on the first line.

根据你提供的信息，可能是因为在使用 Ninja 构建系统时，没有配置 install 目标。你可以检查一下 CMakeLists.txt 文件中是否添加了 install 目标。如果没有，你可以添加以下代码：

install(TARGETS <target_name>
        DESTINATION <destination_folder>)

其中，`<target_name>` 是要安装的目标名称，`<destination_folder>` 是安装目标的路径。例如：

install(TARGETS my_app
        DESTINATION bin)

表示将 `my_app` 应用程序安装到 `/usr/local/bin` 目录下。

如果你已经添加了 install 目标，那么可能是因为你没有使用 sudo 权限运行 `ninja install` 命令。你可以使用以下命令来运行：

sudo ninja install

这样就可以使用管理员权限安装目标了。
