find_package will always fail to find clang-format because there is no cmake module for this.

It turns out that there is fairly simple way to find it though:

find_program(CLANG_FORMAT NAMES clang-format clang-format-3.6 clang-format-3.5 clang-format-3.4)

This picks the first match in the list of names, which is just what I need. It's not totally generic because,
when a new version of clang-format is released, the command needs updating. But that's
acceptable for me.
