Thanks.

Use of std::time_t and std::tm will not compile on all of CMake's platforms.
Other code already uses "#include <time.h>", "time_t", and "struct tm".

Also, IMO the result in the case of failure should be the empty string
rather than NOTFOUND.  The latter is a convention in the find_* commands
that should never have been used elsewhere.

Thanks,
