Hello,

I think your problem is that you are using CMake built without SSL support. Therefore, it cannot download these archives over https. To verify that CMake is compiled with SSL support, you can type the following command in the terminal:  
`strings `which cmake` |grep OpenSSL`

If the output of this command is empty, that means that CMake wasn’t built with SSL support. You should recompile it.  
As a side note, it is always a good idea to build the latest ITK release which is now 4.12.2 .

Hope this helps.

Francois
