This is an example of an external using the STK ("synthesis toolkit") library.
For STK see http://ccrma-www.stanford.edu/software/stk

STK needs C++ exceptions switched on.

The STK tutorial examples assume that a static stk library exists which contains all the
source files (except rt*.cpp) of the stk/src directory.
The library should be compiled multithreaded and with the appropriate compiler flags for 
the respective platform (e.g. __OS_WINDOWS__ and __LITTLE_ENDIAN__ for Windows)
