cannot find C preprocessor cl.exe

这个错误通常是因为缺少C/C++编译器或者编译器路径未设置导致的。如果你使用的是Microsoft Visual Studio，可以按照以下步骤解决这个问题：

1. 打开Visual Studio，创建或打开一个项目。

2. 在菜单栏上选择“项目”->“属性”。

3. 在弹出的对话框中，选择“配置属性”->“常规”。

4. 找到“平台工具集”，选择你所需的工具集版本（如v142）。

5. 确认更改后，重新编译你的项目。

如果你使用的是其他编译器，可以检查你的编译器是否已经正确安装并设置了环境变量。如果还是无法解决问题，可以尝试重新安装或更新编译器。

It seems that you are encountering some errors and warnings during the build process of your project. Here are some possible solutions to the errors and warnings you mentioned:

1. C4996, C4005 warning: These warnings indicate that some functions or variables you are using may be unsafe. You can consider using the safer versions of these functions or variables, such as "wesncpy_s" instead of "wesncpy". To disable these warnings, you can use the "_CRT_SECURE_NO_WARNINGS" preprocessor definition.

2. LNK1104 error: This error usually means that the linker cannot find a particular file that it needs to link your project. In this case, it cannot find the "CMNSHR32.dIl" file. You may need to check your project settings and make sure that the file is included in the correct path.

3. Other warnings: The other warnings you mentioned, such as the macro redefinition warnings, may be caused by conflicting header files or preprocessor definitions. You may need to check your project settings and make sure that there are no conflicting definitions or includes.

Overall, it's important to carefully review the error and warning messages and try to understand the root cause of the issue. You may also need to consult your project documentation or seek help from other developers to resolve the issue.
