| 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. |
