I'm pretty sure there is no way to specify per-architecture variants of
these things.  I believe this was discussed in bug 2492, which you may
want to read (its long).

I suggest filing a bug.  I also think this would be a good feature for
CMake to have, though personally I don't need it.

I think it comes down to CMake's lack of cross-compilation support.
