Okay, I misread the use case here.  The CMAKE_OSX_SYSROOT and
CMAKE_OSX_ARCHITECTURES were created to support builds of OS X
universal binaries where everything was still targeting the same
set of platforms (with a single -isysroot for everything).

CMake has no official support for mixed-platform builds so you will
either have to hack the build rules or help improve CMake to
support this.  There is already support for a per-binary list of
architectures:

Something similar could be created for the other settings.
