| CMAKE_TLS_VERIFY | |
| ---------------- | |
| Specify the default value for the :command:`file(DOWNLOAD)` and | |
| :command:`file(UPLOAD)` commands' ``TLS_VERIFY`` options. | |
| If not set, the default is *off*. | |
| This variable is also used by the :module:`ExternalProject` and | |
| :module:`FetchContent` modules for internal calls to :command:`file(DOWNLOAD)`. | |
| TLS verification can help provide confidence that one is connecting | |
| to the desired server. When downloading known content, one should | |
| also use file hashes to verify it. | |
