Myself, I don't know.  Haven't learned everything about Cygwin, MinGW, 
and VC++ differences.

On MinGW / MSYS, this dies due to what I believe is overloading of the 
root word 'chicken'.  Both the library and the .exe are trying to use 
it, and CMake gets confused.  I've posted about this issue in general on 
the CMake list.  I don't know what the answer will be.
