[CMake] target_link_libraries not working with add_library

[Felipe Ferreri Tonello]

Guys,

I'm doing this:
add_library(lib_base ${sources})
target_link_libraries(lib_base ${libs})

but look at the linker output:
/usr/bin/ar cr liblib_base.a  CMakeFiles/lib_base.dir/diskman.cpp.o 
CMakeFiles/lib_base.dir/netutils.cpp.o 
CMakeFiles/lib_base.dir/base.cpp.o 
CMakeFiles/lib_base.dir/datetime.cpp.o 
CMakeFiles/lib_base.dir/datasource.cpp.o 
CMakeFiles/lib_base.dir/tinifile.cpp.o 
CMakeFiles/lib_base.dir/list.cpp.o 
CMakeFiles/lib_base.dir/memstream.cpp.o 
CMakeFiles/lib_base.dir/misc.cpp.o CMakeFiles/lib_base.dir/stringz.cpp.o 
CMakeFiles/lib_base.dir/critsec.cpp.o 
CMakeFiles/lib_base.dir/threads.cpp.o 
CMakeFiles/lib_base.dir/sockets.cpp.o 
CMakeFiles/lib_base.dir/sockserver.cpp.o 
CMakeFiles/lib_base.dir/sockthread.cpp.o 
CMakeFiles/lib_base.dir/strfunc.cpp.o CMakeFiles/lib_base.dir/ssl.cpp.o 
CMakeFiles/lib_base.dir/rwlock.cpp.o CMakeFiles/lib_base.dir/ipc.cpp.o 
CMakeFiles/lib_base.dir/decContext.cpp.o 
CMakeFiles/lib_base.dir/decimal.cpp.o 
CMakeFiles/lib_base.dir/decimal32.cpp.o 
CMakeFiles/lib_base.dir/decimal64.cpp.o 
CMakeFiles/lib_base.dir/decimal128.cpp.o 
CMakeFiles/lib_base.dir/decNumber.cpp.o 
CMakeFiles/lib_base.dir/decPacked.cpp.o
/usr/bin/ranlib liblib_base.a

see? No linked libraries, only linked objects...

How to proceed?
