Improve CMakeLists.txt

[codedwrench]

The CMakeLists has been hacked together by me in a single file.
It needs to be rewritten for a CMakelists file per folder.

The following features have to work:

• MingW64, MSYS, GCC and MSVC compiler support.

• The different libraries in this project: ncurses/pdcurses, libpcap/npcap, google test, google mock, boost_thread & boost program_options have to be imported properly and based on platform (only windows and linux officially supported)

• Source files need to be found in their subfolders instead of it being a long list of linker files like it is now

• Source files need to be automatically included for the unittest target

• Doxygen needs to be able to be generated

• Doxygen and Unittest building is optional

Bonus points if you add automatic file formatting through clang format.

Now added a cmake subfolder for finding modules, this improved the file a little bit already
