cmake file EXISTS

CMake是一个跨平台的开源构建工具，用于管理软件构建过程。CMake使用CMakeLists.txt文件来描述项目的构建规则和依赖关系。CMakeLists.txt文件通常位于项目的根目录中。

要检查CMakeLists.txt文件是否存在，可以使用以下方法之一：
1. 手动查找：在项目的根目录中查找是否存在名为CMakeLists.txt的文件。
2. 命令行：在项目的根目录中运行命令`ls CMakeLists.txt`（Linux/Mac）或`dir CMakeLists.txt`（Windows），如果文件存在，则会显示文件信息。
3. 编程语言：使用编程语言（如Python）的文件操作函数来检查文件是否存在。

include could not find load file: my_custom_cmake_file.cmake

This error message is indicating that CMake is unable to locate the file "my_custom_cmake_file.cmake" which is being included in your CMakeLists.txt file.

There are a few possible reasons for this error:

1. The file "my_custom_cmake_file.cmake" does not exist in the directory you specified. Double-check the path to make sure it is correct and the file exists.

2. The file "my_custom_cmake_file.cmake" exists, but it is not in the same directory as your CMakeLists.txt file. In this case, you need to specify the full path to the file, or add the directory containing the file to the CMAKE_MODULE_PATH variable.

3. You have misspelled the name of the file or included the wrong file. Double-check the name and make sure you are including the correct file.

Once you have addressed the issue, the error message should disappear, and CMake should be able to find and include the specified file.

CMake Error at /opt/ros/melodic/share/catkin/cmake/atomic_configure_file.cmake:8 (file): error locking file

As an AI language model, I do not have access to the specific details of your system or project. However, this error message suggests that CMake encountered an issue while trying to lock a file during the configuration process. This might be due to a permissions issue, a conflict with another process accessing the file, or an issue with the file itself.

Here are some general troubleshooting steps that you can try:

- Check if the file that CMake is trying to lock actually exists on your system, and if you have the necessary permissions to access it.
- Make sure that no other process is currently using or modifying the file.
- Try deleting the file and re-running CMake to see if it can be recreated without any issues.
- If none of the above steps work, try updating CMake or any related dependencies to the latest version to see if the issue has been fixed.

If you continue to experience this error message, you may need to provide more specific details about your system and project so that others can better assist you.
