[CMake] add_subdiretory() help

[Ramazan Girgin]

I didn't understant your solution. Ex: Modul A built library liba
Modul B built library b and Modul C builds libc and depends liba and libb,
if i do this ;
target_link_libraries(libc liba libb)

if libb doesn't exist , libb will be built before libc??? I know cmake
doesn't do this .must I do another thing?
