I'm having some trouble when trying to compile the source code using cmake. I'm on Unbuntu 22.04 amd64, and when it tries to link the libsfml-graphics.so I get this error message:

As you can see the other modules build fine.

How did you get freetype? It looks like a static library, did you build it yourself?

I've downloaded it at: https://www.sfml-dev.org/download/sfml/2.5.1/
This is the stable version, scroll down it says: All | source code
1. I create a folder in the root dir called: DEBUG
2. I enter that folder with the terminal.
3. Then call: cmake -DCMAKE_BUILD_TYPE=Debug ..
4. Then: make
Where I get those message errors when it tries to compile the sfml-graphics-d module. In the source code there is a folder called 'extlibs' but I think is for OS Windows, maybe somehow it compiles some static libraries from that? or uses it!? Because previously I've tried to build statically and it works, then I installed with 'make install'.

SFML doesn't ship binaries for Linux, as such you won't have gotten those file from SFML itself.
Either way, I recommend to just install libfreetype-dev or whatever the freetype development package is called in your distro's package manager, which should then install a system-compatible version.
Then clear the CMake cache a build SFML fresh and I guess make sure, CMake isn't picking up the rogue freetype library.

Solved.
I simply remove manually this 'libfreetype.a' file from '/usr/local/lib' and do this basic process of compiling with cmake as I've described above. My system already has the 'libfreetype-dev'.
I don't know how it appears but, that is it.
Thanks for your attention eXpl0it3r.
