Fail to compile steem

Hi,

I'm trying to compile the latest version

following the building instraction for Ubuntu 14.04

https://github.com/steemit/steem/blob/master/doc/building.md

cmake -DCMAKE_BUILD_TYPE=Release ..

fail on:

 CMake Error at libraries/manifest/CMakeLists.txt:28 (message):

 Could not get plugin dependencies

  -- Configuring incomplete, errors occurred!

 See also "/home/steem/build/CMakeFiles/CMakeOutput.log".

Didn't find any clue in the log.

How to fix it?
