It is quite inexact because a target can store many information like include 
directories or preprocessor definitions for example (through properties like 
INCLUDE_DIRECTORIES or COMPILE_DEFINITIONS).

So it make sense to enable to specify link libraries to a static library using 
PRIVATE or PUBLIC to ensure various settings are propagated to the static 
library compilation step.
