The way they have this setup with cmake is such that it seems to add
-msse on to the Fedora defaults. I think they are going to want that
to be the normal case when building for linux. Under those circumstances,
am I supposed to ask them to put in a test for Fedora in the cmake
build file or is there some standard way of adding -msse when options
aren't specified from rpm, but it is added when they are not?
I am not sure what I am supposed to recommend to upstream other than perhaps
something they aren't likely to do.

Changing the cmake specs in the spec file won't be hard.
