Replacing file GLOB usage with explicit file mentions.

In a CMakeLists.txt (here) file we have used file(GLOB <Var> ./*.cpp) like functions which is not a good practice.

So, what i would like to have is CMakeLists.txt for each folders and add_subdirectory(<folders>) in the root CMAKE. Try to explicitly locate each source file and link it with target.
