MEX Error when complining SPAMS

I downloaded SPAMS 2.6 from the official website, and I ran compile.m, but I keep receiving this error:

Error using mex
MEX cannot find library 'gomp', specified with the -l option.
 MEX searched for a file with one of the following names:
 gomp.lib
 libgomp.lib
 Verify the library name is correct. If the library is not
 on the existing path, specify the path with the -L option.


Error in compile (line 447)
    mex(args{:});

Not sure how to approach it. I tried searching for any of the libraries mentioned in the error but didn't find them. I have Matlab 2018b.
