Mex files not compiling

[RRiesgo]

Hello!

I've tried running the code, but it keeps giving an error message that it can't compile. I followed the instructions on the code itself, installed MinGW64 and did the mex setup. However when I try either running the code itself, or compiling the lib folder cpp files with mex, matlab says that I don't have the necessary GSL libraries. I downloaded GSL 2.7.1.1, copied the libraries on matlab execution path but no luck. I even tried getting into the MinGW64 installation path and copying the GSL libraries there, but still they aren't being detected. What step could I be missing? Is there a specific path where I need to put the libraries that I might have missed? Thank you very much beforehand for any advise you can give me.
