CMAKE_TLS_VERSIONΒΆ
New in version 3.30.
This is a CMake Environment Variable. Its initial value is taken from the calling process environment.
Specify the default value for the file(DOWNLOAD) and
file(UPLOAD) commands' TLS_VERSION option.
This environment variable is used if the option is not given
and the CMAKE_TLS_VERSION cmake variable is not set.
See that variable for allowed values.
This variable is also used by the ExternalProject and
FetchContent modules for internal calls to
file(DOWNLOAD) and git clone.
