# This is basically the overall name of the project in Visual Studio this is the name of the Solution File
# For every executable you have with a main method you should have an add_executable line below.
# For every add executable line you should list every .cpp and .h file you have associated with that executable.
# You shouldn't have to modify anything below this line
