Switching from ubuntu to mac (X11), why aren't libraries being detected?

Question

macOS

So, there is some program that works in ubuntu like this and actually has such a file

This is actually here in order to understand that the program itself works correctly
I downloaded X11 on mac, installed xcode
I didn’t see X11
libraries with stackoverflow, I also tried to simply transfer all the libraries from the X11 folder to usr/include, also instead of a shortcut to X11 in the usr folder I put the folder itself, nothing helps
It's rather dreary to add libraries to the project, since they have other libraries inside, then which are also not located, etc.
There is nothing to say about more complex programs.
How to decide once and for all?
