drogon_ctl create subdirectory <subdirectory_name>

I have an existing mac os x project that I want to add drogon to. I have some mac specific settings in the CMakeLists.txt file, and I would rather not swiss-army-knife the project. By swiss-army-knife, I mean add too many different functions to the same project. This creates ambiguity and risks in editing and maintaining the code. To resolve this problem, there can be a "drogon_ctl create subdirectory " command that creates a subdirectory with a library based CMakeLists.txt file that works with a parent cmake file that uses the add_subdirectory command. As of now, I tried creating a project and moving it into a subdirectory, but there were link errors. If you can help those of us who say "no" to swiss-army-knife coding, I would appreciate it! 😉✌🏻
