First question. Did you download the static libraries?
I can only offer an opinion on GNU/Linux boxes which states that static linking will skip dynamic linking and linking all functionality with object files (.o) or archive files (.a). I'm not sure what the Windows equivalent is to a archive file or static linking.
The first picture shows you have access to easy.h.
The last picture shows you've missed adding / linking easy.lib.
When you downloaded th original package, easy.lib should have been in the lib directory. Was it not there?
