Hi Dennis --

This really doesn't have anything to do with KDevelop -- this is basic Linux library usage.  Anytime you use a library you have to configure the linker to use it as well.  I don't know how to do that in KDevelop (never used it, don't have it installed), but look for something where you can add options to the project's "linker flags" -- there you'll want to add "-ltag" (which tells the linker to link to TagLib).

Also note, for the future, questions like this should go to the development list:  taglib-devel at kde.org
