CMAKE_TLS_VERSIONΒΆ

New in version 3.30.

Specify the default value for the file(DOWNLOAD) and file(UPLOAD) commands' TLS_VERSION option. If this variable is not set, the commands check the CMAKE_TLS_VERSION environment variable.

The value may be one of:

  • 1.0

  • 1.1

  • 1.2

  • 1.3

This variable is also used by the ExternalProject and FetchContent modules for internal calls to file(DOWNLOAD) and git clone.
