Usage cmake [options] <path-to-source> cmake [options] <path-to-existing-build> cmake [options] -S <path-to-source> -B <path-to-build> Specify a source directory to (re-)generate a build system for it in the current working directory. Specify an existing build directory to re-generate its build system. Run 'cmake --help' for more information.

这是CMake的使用说明，它包含三种使用方法：

1. 指定源代码路径生成构建系统：

cmake [options] <path-to-source>

在当前工作目录下生成一个构建系统，用于构建指定路径下的源代码。

2. 指定已有的构建目录重新生成构建系统：

cmake [options] <path-to-existing-build>

重新生成指定路径下的构建系统。

3. 指定源代码路径和构建目录生成构建系统：

cmake [options] -S <path-to-source> -B <path-to-build>

在指定的构建目录下生成一个构建系统，用于构建指定路径下的源代码。

其中，`[options]`是可选的CMake选项，用于指定生成构建系统的相关参数。例如，可以使用`-DCMAKE_BUILD_TYPE`选项指定编译类型。

更多使用方法和选项，请参考`cmake --help`命令。

It seems that there is an issue with the build process of your project. The error message indicates that the source directory specified does not exist.

There could be a few reasons for this error. Here are a few steps you can try to resolve the issue:

1. Make sure that the source directory path specified in your CMakeLists.txt file is correct. Double-check the path and ensure that it matches the actual location of your source code.

2. Verify that the necessary files and directories are present in the specified source directory. It's possible that the required files are missing or have been moved.

3. If you have recently renamed or moved your project files, try deleting the existing build directory and rebuilding the project from scratch. This will ensure that the build process starts fresh and picks up any changes made to the project structure.

4. If you are using an IDE like CLion, try using the built-in clean and rebuild options to clear any cached build artifacts and perform a clean build.

If these steps do not resolve the issue, please provide more information about your project structure, CMakeLists.txt file, and any relevant code snippets so that I can assist you further.

cmake项目怎么输出重定向

引用\[1\]:安装成功后应该能够在命令行中执行cmake命令： $ cmake Usage cmake \[options\] &lt;path-to-source&gt; cmake \[options\] &lt;path-to-existing-build&gt; cmake \[options\] -S &lt;path-to-source&gt; -B &lt;path-to-build&gt; Specify a source directory to (re-)generate a build system for it in the current working directory. Specify an existing build directory to re-generate its build system. Run 'cmake --help' for more information. 引用\[2\]:CMake脚本文件由CMake命令组成，后缀通常为.cmake（本质上和CMakeLists.txt没有区别）。用法： cmake \[-D &lt;var&gt;=&lt;value&gt;\]... -P &lt;cmake-script-file&gt; \[&lt;args&gt;...\] 引用\[3\]:完整的项目目录结构如下： cmake-demo/ CMakeLists.txt hello_world.cpp hello/ CMakeLists.txt hello.h hello.cpp cmake-build/ # CMake自动创建 ... hello_world # 可执行程序 hello/ ... libhello.a # hello库 引用\[4\]:CMake命令行工具 。

回答: 在CMake项目中，可以使用重定向来将输出结果保存到文件中。在命令行中，可以使用以下方式来实现输出重定向：
$ cmake \[options\] <path-to-source> > output.txt
这将把cmake命令的输出结果重定向到名为output.txt的文件中。你可以将output.txt替换为你想要保存输出结果的文件名。\[1\]

另外，在CMake脚本文件中，你也可以使用重定向来将输出结果保存到文件中。在CMake脚本文件中，可以使用以下方式来实现输出重定向：
execute_process(COMMAND cmake \[options\] <path-to-source> OUTPUT_FILE output.txt)
这将把cmake命令的输出结果重定向到名为output.txt的文件中。你可以将output.txt替换为你想要保存输出结果的文件名。\[2\]

总结起来，无论是在命令行中还是在CMake脚本文件中，你都可以使用重定向来将cmake命令的输出结果保存到文件中。这样可以方便地查看和分析cmake命令的输出信息。
