I’m seeing a similar error when setting CMAKE_OSX_DEPLOYMENT_TARGET to 10.7 with XCode 8, and leaving CMAKE_OSX_SYSROOT unset. I’m couldn’t identify where (from Modules/Platform/Darwin.cmake) the detected value of _CMAKE_OSX_SYSROOT is computed. (I don’t wish to explicitly set it) Kind regards, James
