# debug_which: (in)
# Is one of the following cases:
#
# Case debug_even:
# The files with an even (odd) index in source_list have debug (release) flags.
#
# Case debug_odd:
# The files with an odd (even) index in source_list have debug (release) flags.
#
# Case debug_all, debug_none, or empty string:
# The debug and release flags are not set by this routine.
#
# source_list: (in)
# is a list of source files that get set to have debug or release
# compile flags. The cppad_cxx_flags compile flags always get included.
