[Cmake] Auto-generating exports for Windows DLLs

I talk about this in the cmake book on page 43.  I have a small
example that works with a perl script.   It only works with visual studio.
I have attached the example files.  What is really needed now is a non-perl
version of makedef that works with borland and visual studio.
