| |
| .. include:: ENV_VAR.txt |
| |
| Specify the default value for the :command:`file(DOWNLOAD)` and |
| :command:`file(UPLOAD)` commands' ``TLS_VERSION`` option. |
| This environment variable is used if the option is not given |
| and the :variable:`CMAKE_TLS_VERSION` cmake variable is not set. |
| See that variable for allowed values. |
| |
| This variable is also used by the :module:`ExternalProject` and |
| :module:`FetchContent` modules for internal calls to |
| :command:`file(DOWNLOAD)` and ``git clone``. |
