fatal error: VL6180X.h: No such file or directory compilation terminated.

It seems like you encountered a compilation error with the VL6180X.h file. This error message indicates that the compiler couldn't find the VL6180X.h header file in the specified directory.

To resolve this issue, you need to make sure that you have properly installed the VL6180X library and included the correct path to the header file in your code.

Here are a few steps you can follow to fix this error:

1. Check if you have installed the VL6180X library correctly. Make sure you have downloaded and installed all the necessary dependencies.

2. Verify the location of the VL6180X.h file. Double-check if the file exists in the specified directory. If not, you might need to download the library again or place the header file in the appropriate location.

3. Ensure that you have included the correct path to the header file in your code. Use angle brackets (<>) for system libraries or double quotes ("") for user-defined libraries. For example:

   #include <VL6180X.h>  // for system libraries
   
   // or
   
   #include "VL6180X.h"  // for user-defined libraries

4. If you have installed the library in a non-standard location, you might need to specify the include path explicitly in your compiler flags or settings.

By following these steps, you should be able to resolve the "No such file or directory" error related to VL6180X.h.
