| CMAKE_TLS_VERSION |
| ----------------- |
| |
| .. versionadded:: 3.30 |
| |
| Specify the default value for the :command:`file(DOWNLOAD)` and |
| :command:`file(UPLOAD)` commands' ``TLS_VERSION`` option. |
| If this variable is not set, the commands check the |
| :envvar:`CMAKE_TLS_VERSION` environment variable. |
| If neither is set, the default is TLS 1.2. |
| |
| .. versionchanged:: 3.31 |
| The default is TLS 1.2. |
| Previously, no minimum version was enforced by default. |
| |
| The value may be one of: |
| |
| .. include:: include/CMAKE_TLS_VERSION-VALUES.rst |
| |
| This variable is also used by the :module:`ExternalProject` and |
| :module:`FetchContent` modules for internal calls to |
| :command:`file(DOWNLOAD)` and ``git clone``. |
