Are you using CMake?  I don't recognize the code you post - if you are 
looking for help specifically for a visual studio project, this is not 
the right forum for your question.  In CMake, you'd do it something like 
this:

add_library(libfoo libsource.cpp libsource.h libsource2.cpp)
add_executable(foo foo.cpp foo2.cpp)
target_link_libraries(foo libfoo)
