commit 73a70b33ae68d7b38d3c69cb198fb33e70a76b6b (HEAD -> get_cmake_from_github, github/get_cmake_from_github)
Author: Robert Maynard <[email protected]>

    Download CMake sources from the Github releases
    
    Now that CMake is providing CMake release artifacts on github,
    we should prefer those as they have better download speeds and
    uptime.
