# This is what a project would use if it worked around the macro implementation by doubling its
# backslashes.
# The four backslashes below become two when cmake unescapes the quoted argument, and the macro's
# argument substitution consumes one more level, so the value reaches the command as a\b, which is
# what such a project intends.
# The function implementation does not consume one level, so
# the same source would arrive as a\\b.
# Projects in that situation set QTP0008 to OLD until they
# can drop the extra escaping.
