Is there a reason why you want to do that ?
You can also simply set some variables which will contain the lists of source files, and then combine these to libs and apps as you want:

set(foolibSrcs src1/foo.c src1/foo2.c)
 
set(barlibSrcs src2/bar.c src1/bar2.c)

add_library(foolib_static STATIC ${foolibSrcs})
add_library(foolib_dyn SHARED ${foolibSrcs})
add_library(barlib_dyn SHARED ${barlibSrcs})
add_library(all_in_one SHARED ${foolibSrcs} ${barlibSrcs})
add_executable(blub main.c ${foolibSrcs} ${barlibSrcs})

Bye
