ENH: Set minimum supported macOS deployment target directly in CMake configuration

hjmjohnson · hjmjohnson · commit f6784f8c851a · 2026-01-07T08:58:00.000-06:00
The value of 10.11 was hard-coded for the external project build, but was not exposed at
the SuperBuild level.  This change makes the setting
of the OSX_DEPLOYMENT_TARGET more transparent.
