A project dependency does not add the library. All it does, is ensure 
that the project is built before your project.

Your static library project should have created a library called 
"libA.a". This will be in a directory called Debug or Release, relative 
to your project.

In you executable project you need to add a library path:
${workspace_loc:A}/Debug, or
${workspace_loc:A}/Release
depending on whether you want the debug or release build of the library

You also need to add it to the list of libraries to link wth. Add
A
to the list of libraries.
VERY IMPORTANT NOTE: DO NOT add "libA.a" or any combination. The GNU 
linker automatically adds a "lib" prefix and a ".a" suffix to whatever 
you specify. If you need more information on the GNU linker, RTM.
