Automatically add dependency during the build

[xxks-kkk]

Consider how we build LC138 binary in C++

add_executable(138
  leetcode/138-CopyListWithRandomPointer/copyListWithRandomPointer.cc
  include/cppinclude/linkedList_rand.cc
  include/cppinclude/cpputility.h
  include/jsoncpp/jsoncpp.cpp)

Is there a way to include jsoncpp.cpp automatically whenever we include the .cc that has dependency on it (e.g., linkedList_rand.cc has dependency on jsoncpp.cpp. Can we include jsoncpp.cpp whenever we use linkedList_rand.cc automatically?)
