Thank you Robert for a quick response.  I have indeed tried
different values for MACOSX_DEPLOYMENT_TARGET.  The serialization
library and the test program compiled and ran OK when deployment
target was set to 10.9, 10.10 and when left unset.  Presumably when
MACOSX_DEPLOYMENT_TARGET is not present xcode builds for the current
OS X version, which is 10.10 in my case.

The link step fails when MACOSX_DEPLOYMENT_TARGET is 10.7 or 10.8.

Would you have a pointer on how to build boost serialization with
CMake?  I was not able to quickly find such instructions at the
boost page or in serialization repository.  Perhaps CMake
has different rules than bjam on setting compiler options when
MACOSX_DEPLOYMENT_TARGET is in the environment.

Thank you,
