Can't find compiled binding library on MacOS

`libgodot-cpp.osx.debug.64.a` was compiled to `godot-cpp/bin`

However if I run:
```
clang -o bin/libtest.so -shared src/init.os -Lgodot-cpp/bin -llibgodot-cpp.osx.debug.64.a
```

I get this error:
```
ld: library not found for -llibgodot-cpp.osx.debug.64.a
clang: error: linker command failed with exit code 1 (use -v to see invocation)
```
