Update included copy of rhash to version 1.4.4?
CMake provides a copy of rhash, it seems to be old (COPYING indicates 2005?) and reduced to the algorithms that are actually used by CMake. Upstream rhash released version 1.4.4 this summer. Would it be worth to synchronize CMake's copy with upstream?
If yes:
- Is it okay to upstream improvements made in CMake's copy to rhash? The licenses are not identical (0-clause BSD).
- Should the reduction of rhash inside CMake be preserved?
