title: Apache Thrift errors with CMakeLists.txt
body: <p>I am trying to build the C++ library for Apache Thrift and I am getting a cmake error that I cannot quite decipher, this is the series of steps I followed to get the error</p>
  
  <pre><code>git clone https://git-wip-us.apache.org/repos/asf/thrift.git
  cd thrift/lib/cpp
  mkdir cmake-build
  cmake ..
  </code></pre>
  
  <p>And the error I get is </p>
  
  <pre><code>CMake Error at CMakeLists.txt:162 (include):
    include could not find load file:
  
      ThriftMacros
  
  CMake Error at CMakeLists.txt:164 (ADD_LIBRARY_THRIFT):
    Unknown CMake command "ADD_LIBRARY_THRIFT".
  </code></pre>
