Yes, this will work. > Also, Kyle said linking against lib2 will link against both lib1 and > lib2. Is there a static way of checking the relation between lib1 and > lib2 ? Separately and after using INTERFACE option with lib1 and > lib2. Asking "does lib1 link against lib2" has long been a requested feature of CMake, but unfortunately, the existence of generator expressions precludes this hypothetical feature. Because target_link_libraries() supports generator expressions, which means the linking could change based on the configuration (Debug, Release, etc.), we don't actually know if lib1 links against lib2 until generate time, at which point it's too late to do anything in configure time.
