[Rtk-users] Cannot download ExternalData during build (RTK 2.0)

[Andreas Andersen]

Then it must be the command CMake issues under the hood which doesn't
support the protocol.
>From the documentation of "file(DOWNLOAD ...)" (which is called by
ExternalData):
For https:// URLs CMake must be built with OpenSSL support. TLS/SSL
certificates
are not checked by default. Set TLS_VERIFY to ON to check certificates
and/or use EXPECTED_HASH to verify downloaded content. If neither TLSoption
is given CMake will check variables CMAKE_TLS_VERIFY and CMAKE_TLS_CAINFO,
respectively.

So if you compiled CMake yourself, make sure you enabled OpenSSL

Best regards
Andreas
