[CMake] Debugging the ExternalProject_Add download step

[David Cole]

Yes, there's a problem with https. By default, ctest does not link to
a curl that has openssl enabled.

If you need to download from an https-only site, you'll need to build
your own ctest that does have openssl enabled.

Alternatively, find a place (or make your own) to get the download
from that is not behind https.


HTH,
David
