5.1 The easy way
For this version, you can use either the GNU style "configure;make"
style build process, or the old ACS style. If it works for you, use
the GNU style.
For the GNU style build, just type "./configure" then "make" from the
project's root directory. This will configure both the model compiler
and the simulator, and then build the model compiler first, then use
it to build the simulator. That should be all that is needed. You do
