GPT4:
The error message “No such file or directory” typically means that the compiler can’t find the file you’re trying to include.

CGAL/disable_warnings.h is a header file from the Computational Geometry Algorithms Library (CGAL). If you’re getting this error, it probably means one of the following things:

CGAL is not correctly installed on your system. You can download it from https://www.cgal.org/download.html.

The include path for CGAL is not correctly set in your project settings or makefile. If CGAL is installed, but your compiler doesn’t know where to look for it, you’ll need to add the correct directory to your include path.

The file disable_warnings.h doesn’t exist, has been deleted, or has been moved to a different location. This seems unlikely because disable_warnings.h is a part of CGAL, and so should be included when you install the library.

To fix the error, you should double-check that CGAL is installed correctly and that your compiler knows where to find it. If you’re using a build system like cmake or a specific IDE, you might need to update some settings there.
