I think you'll find I am the maintainer of Poco on Cygwin :-)

Whilst you're welcome to take Cygwin's Poco packages from any Sourceware 
mirror (e.g. [1]), this really isn't a good idea. Poco is dependent on 
enough other libraries that the Poco packages aren't useful or 
meaningful in isolation.

This is why Cygwin has a setup executable that manages these 
dependencies for you. If you choose to install 'libpoco-devel' (say), 
you get appropriate versions of other dependent packages installed at 
the same time. And if one of these dependencies updated introducing an 
API change, Poco would be rebuilt. A stand-alone package without this 
dependency resolution isn't a great deal of use.

Dave.
