How do you read iges files in matlab?

I tried it with the IGES toolbox: https://www.mathworks.com/matlabcentral/fileexchange/13253-iges-toolbox

close all;clear all; clc

% example.m plots an IGES CAD-object
% Compile the c-files
makeIGESmex;
% Load parameter data from IGES-file.
[ParameterData,EntityType,numEntityType,unknownEntityType,numunknownEntityType]=iges2matlab('IGESfiles/60.igs');
% Plot the IGES object
plotIGES(ParameterData,1);

I get the following error:

Undefined function or variable 'makeIGESmex'.

Error in iges2matlabexample (line 5)

makeIGESmex;

I saved the igesToolbox.mltbx file to the current directory, so that can't be the issue.

Whoops, forgot to install the toolbox.
