Yes, and that's why a config file would be the answer for those.

It may be beneficial to have the CMake option for simple triples, for
now as an implementation example, but later override it with the
config file.

We could even keep the CMake options in conjunction with the config
file, but that'd have to be well documented so people understand what
overrides what.
