# This is pretty ugly...details below
# The program depends on both C++ and CUDA Objects, but storing CUDA objects as .o files results in circular dependency
# warnings from Make. However, nvcc requires that object files for linking end in the .o extension, else it will throw
# an error saying that it doesn't know how to handle the file. Using a non .o rule for Make and then renaming the file
# to have the .o extension for nvcc won't suffice because the program will depend on the non .o file but the files in
# the directory after compilation will have a .o suffix. Thus, when one goes to recompile the code all files will be
# recompiled instead of just the ones that have been updated.
#
# The solution below solves these issues by silently converting the non .o suffix needed by make to the .o suffix
# required by nvcc, calling nvcc, and then converting back to the non .o suffix for future, dependency-based
# compilation.
