CMakeLists.txt

# This file specifies how the project should be built, using CMake.
# If you are unfamiliar with CMake, don't worry about all the details.
# The sections you might want to edit are marked as such, and 
# the comments should hopefully make most of it clear.
#
# For many purposes, you may not need to change anything about this file.
