CMAKE_TLS_VERIFYΒΆ
Specify the default value for the file(DOWNLOAD)
and
file(UPLOAD)
commands' TLS_VERIFY
options.
If this variable is not set, the commands check the
CMAKE_TLS_VERIFY
environment variable.
If neither is set, the default is off.
This variable is also used by the ExternalProject
and
FetchContent
modules for internal calls to 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.
