we may want to do if DEFINED $CACHE{...} OR DEFINED $ENV{...} as both are valid ways for the user to express intent.

the non-cache CMAKE_OSX_DEPLOYMENT_TARGET can be defined too - we may want to ignore it, or raise a warning (since CMake documentation says that it may be overwritten completely during the call to project) - that could be an elseif()
