build error, you added X to INCLUDE path, you should use Y instead.

[nimafo]

Hi all,
I am using Cmake to build my solution on mac M1 with g++ compiler,
after make I get this error:

error: You have added .../path/to/CGAL-x.y/include/CGAL to the INCLUDE path. You should use .../path/to/CGAL-x.y/include instead.

What is the problem here? how can I resolve this?

[AgarwalSaurav]

In the header file of your program, you could have the following statement to add Arrangement_2.h from CGAL. Note that CGAL/ is prepended.

#include <CGAL/Arrangement_2.h>

Then in the Makefile you could do -I../path/to/CGAL-x.y/include/

[nimafo]

I tried this and did not work,
Maybe better to put the complete log:

Thanks @sloriot, but I still get the same error after running make.

Try removing CMakeCache.txt. Somebody/something added /opt/homebrew/Cellar/cgal/5.5.1/include/CGAL in include directories.
