Library not loaded: @rpath/libMatlabEngine.dylib

I'm pretty much a novice when it comes to coding. I'm trying to visualize a game in C++ using Matlab. The makefile was partially given as part of the exercise. I tried fixing the problem by using this: https://de.mathworks.com/help/matlab/matlab_external/custom-linking-to-required-api-libraries.html

The code works but when trying to implement the "GUI" this error comes up:
