| 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. Otherwise, the value defaults to empty, |
| so no explicit ``-isysroot`` flag is passed, and the compiler's default |
| sysroot is used. |
| |
| .. versionchanged:: 4.0 |
| The default is now empty. Previously a default was computed based on |
| the :variable:`CMAKE_OSX_DEPLOYMENT_TARGET` or the host platform. |
