# This will also copy the kernel source file parallel.cl (created by you) to the build directory
# The copying command is unfortunately not perfect, as it doesn't redo the copy if you only edit
# the parallel.cl, but leave the parallel.c untouched.
# Because of this, you might need to force 'Rebuild All' to ensure kernel code updates propagate
# to the build directory. If you know enough CMake magic, feel free to fix this and let me know.
