Well, you can obviously only select targets that actually exist in a project. Thus, if you use your own project, you need to create those two targets. In the one that I posted, those targets exist already.
Go to "project options", and under the build targets tab, add three new targets (on the left side). You can choose whatever name you want. I recommend using the respective component's name for clarity, but it can really be anything.
For each of them, select "static library" on the right, and give it a meaningful output file name (the standard is libxxxxxxx.a, so you would for example want to use lib/libgoo.a. Although it does not really matter what names you choose, following the standard is good. It allows you to add the lib directory to linker options later and just use goo. The linker will then figure out that it has to be lib/libgoo.a, which is a good thing -- otherwise you would have to provide a full pathname). Also, by adhering to the standard, you are compatible with the rest of the world, so your projects will work with everybody else's.
Then, for each target, check the sources that have to go into that library (on the bottom of the dialog). If unsure, look in the build batch file. You can add headers, but you don't need to (adding headers will allow you to open them in the IDE if you want to edit them, but for the build, it does not matter).
Close "project options".
Finally, under "build options", in the linker tab, add the libraries that will be generated by above targets to "link libraries". If you have done everything "the standard way", you can just use the short names and add lib to linker search dirs. Otherwise, click on the "..." and find them with the file selector.
