Summary0014674: SSL support on OS X not working
DescriptionIt seems that CMAKE_USE_OPENSSL is not enabled in the Homebrew and Macports builds of cmake. Thus, the cmake that most Mac-based devs use is going to fail mysteriously (producing a 0-byte file) for URL downloads that use https.

While one could go the route of getting Homebrew, Macports, etc to change their build configs, there's also the issue that openssl is deprecated on OS X anyway, so perhaps OS X builds should default to using Apple's libcurl, which links against the Apple-blessed replacement to openssl.
Steps To ReproduceUse URL in ExternalProject_add with an https:// url.

CMake provides a CMAKE_USE_SYSTEM_CURL option to enable use of the system curl. We expect packagers to enable the use-system-libs options and provide all the dependencies through their packaging tools. If they provide openssl then they should enable CMAKE_USE_OPENSSL too.

However, your suggestion is valid. If CMAKE_USE_SYSTEM_CURL is enabled on OS X we could make that also enable SSL since it is known to work. IIRC the only reason CMAKE_USE_OPENSSL is optional is to avoid requiring users to have OpenSSL just to install CMake to build some code.
