[noway]

Non-critical warnings, but probably worth fixing:

Hey @noway I can understand how annoying these warnings are, I have raised a PR to fixed the project attribute issue. But the cmake version issue in currently not fixable due to the leveldb dependency using an older version of it. https://github.com/google/leveldb/blob/6721eda0b46654d3531b4a0a00c90dc659b337d6/CMakeLists.txt#L5
