MACOSX_DEPLOYMENT_TARGET is a CMake environment variable, so it isn’t possible for a CMake file to set the MACOSX_DEPLOYMENT_TARGET Xcode build setting directly. Instead, set the CMAKE_OSX_DEPLOYMENT_TARGET CMake variable, which ultimately sets the MACOSX_DEPLOYMENT_TARGET Xcode build setting.
Unlike in this Stack Overflow answer, I haven’t found it necessary to set it as a cached variable explicitly, so maybe that’s changed since 2015 or somehow works differently in the context of the mbgl build system.
