CMake: Use FATAL_ERROR if user-supplied options aren't understood.

This way typos are caught quickly and compounding error messages
are avoided (a single typo could cause more than one error).

This keeps using SEND_ERROR when the system is lacking a feature
(like threading library or sandboxing method). This way the whole
configuration log will be generated in case someone wishes to
report a problem upstream.
