Thanks, I'll change the script

I'll try lipo
I've been using "tool -fahv" to see that they are built X86_64 but not deployment target.

I understand that these variables exist, but you are correct that I didn't know how to properly use them.  Now I know how to use them with Xcode were is the documentation on these and the other specific Mac OS X variables that do exist in Cmake but are not documented anywhere I can find on their web site.
These variables:
CMAKE_OSX_DEPLOYMENT_TARGET
CMAKE_OSX_SYSROOT
CMAKE_OSX_ARCHITECTURES
and I am sure there are other OS X specific variables in Cmake that are not mentioned, or documented
