Cygwin's mkisofs is really an alias, and this does a soft link. These do not work with the build.
Instead, downloan the .exe from http://svnpenn.blogspot.com/2011/06/mkisofs-for-windows_24.html
NB: Test your environment variables by opening a Cygwin shell and typing 'which mkisofs'. This should return the path to the mkisofs executable.
