CMake should be built with OpenSSL support

[jfpanisset]

Currently CMake is built without OpenSSL support, since an OpenSSL Conan dependency is "messy".

aswf-docker/packages/conan/recipes/cmake/conanfile.py

Line 37 in e5cec3e

"with_openssl": False, # ASWF: Avoid bringing in OpenSSL dependency

But this results in a version of CMake which cannot download from https URLs:

CMake Error at ilmbase-stamp/download-ilmbase.cmake:163 (message):
  Each download failed!
    error: downloading 'https://github.com/AcademySoftwareFoundation/openexr/archive/refs/tags/v2.5.7.zip' failed
          status_code: 1
          status_string: "Unsupported protocol"
          log:
          --- LOG BEGIN ---
          Protocol "https" not supported
  closing connection #-1
          --- LOG END --

We already have an OpenSSL wrapper Conan recipe, it needs to be moved into ci-common so CMake can be built against it.
