Not a bug but it will maybe save some time to other c++ beginners one day!
In order to use Poco::Path on a default windows/codeblocks openframeworks project (emptyExample), I had to add ‘-liphlpapi’ in the “other linking options”.
that’s it ^^
Hey thanks - that did save some time!
First google result for “codeblocks poco linking order” 
We should get this in for the next release.
