CMAKE_OSX_SYSROOT ----------------- Specify the location or name of the macOS platform SDK to be used. CMake uses this value to compute the value of the ``-isysroot`` flag or equivalent and to help the ``find_*`` commands locate files in the SDK. If not set explicitly the value is initialized by the ``SDKROOT`` environment variable, if set, and otherwise computed based on the :variable:`CMAKE_OSX_DEPLOYMENT_TARGET` or the host platform. .. include:: CMAKE_OSX_VARIABLE.txt
