  I'm getting the same error on OSX 10.9.5:
  
  CMake Error at CMakeLists.txt:10 (eth_policy):
  Unknown CMake command "eth_policy".

  You need to clone the cpp-ethereum-cmake repository next to cpp-ethereum as mentioned in the build docs:
  
  git clone https://github.com/ethereum/cpp-ethereum-cmake
  
  https://github.com/ethereum/cpp-ethereum/wiki/Building-on-Ubuntu

  This worked for me. Thanks TheSquirrel!

  The process changed again, sorry for the inconvenience. The easiest way to build everything now is to do
  git clone --recursive https://github.com/ethereum/webthree-umbrella cd webthree-umbrella mkdir build cd build cmake .. make -j 8
  Or if you only want a specific binary, replace the last command by
  make -j 8 solc

  @chriseth my cmake command fails at
  
  # set cmake_policies
  include(EthPolicy)
  eth_policy()
  
  for the webthree-umbrella CMakelist.txt
  
  I have no problem compiling cpp-ethereum that CMakelist.txt contains the same include.
  
  Any ideas?

  I had the same problem. It seems ethPolicy, and all the other Eth files are in webthree-helpers. You need to git clone webthree-helpers.

  I am on Win 10 64Bit.
  I have followed the instruction on the WIKI and I also get the error:
  
  CMake Error at CMakeLists.txt:10 (eth_policy):
  Unknown CMake command "eth_policy".
  
  I see THREE different software repositories, one the cpp-ethereum-cmake is under username and password from github.
  
  Can some one Please, post the correct software repository, that cmake correctly functions in.
  it would be best to have some one update the WIKI and place all of the code under one github repository.
  
  
  Thank You

  same error for me
  i copied eth_policy.cmake from the cpp-ethereum-cmake DIR, and renamed it to eth_policy
  I did the same with the next files appearing in the CMakeLists.txt
  It worked till the end, but finally some other errors appeared

  I was finally able to get this to work.
  1. git clone https://github.com/ethereum/webthree-umbrella
  2. run getstuff.bat in webthree-umbrella\webthree-helpers\extdep directory
  3. create webthree-umbrella\build
  4. run "cmake .." from webthree-umbrella\build

  I downloaded the content of webthree-umbrella\webthree-helpers\extdep and:
  - the .bat file shows errors
  - the cdmake creates a further mess of recursive folders

  @segovro What kind of errors does the .bat file show?
  
  There are 2 ways to build our projects as of this moment. Check here for details.
  
  In Windows you do need to go inside the extdep directory and run the .bat file in order to obtain all of the dependencies.
  
  Please do not manually copy around stuff, it is not required (and will probably cause other issues which we will be unable to help you with)

  Ok the right answer was already given by CHRISETH
  you need git clone --recursive https://github.com/ethereum/webthree-umbrella
  
  The --recursive flags adds all the modules .Otherwise they will be EMPTY!
