Thank you. This probably means that you need to wait until you decide to support just CMake 2.8.10/2.8.11 or newer, judging from this: https://github.com/Kitware/CMake/commit/beb8a8309bc0ce08e4884a59329607ac09c322ac and the changelog mentioning "ExternalData: Add support for SHA 1 and 2 hash algorithms" in Release notes for 2.8.11?

Thank you for the answer.

Yes. I try to find the data (name, version, checksum), copy it and install it separately. In the way that MacPorts work that makes more sense and is easier to control.
