Cpp runtime does not build using CMake 3.2

[ryanbinns]

cmake complains with:

CMake Error at CMakeLists.txt:31 (CMAKE_POLICY):
  Policy "CMP0059" is not known to this version of CMake.

when using CMake 3.2. Policy CMP0059 was only introduced with CMake 3.3, although the README.md specifies a minimum CMake version of 2.8. This block of code is the issue:

if(CMAKE_VERSION VERSION_EQUAL "3.0.0" OR
   CMAKE_VERSION VERSION_GREATER "3.0.0")
  CMAKE_POLICY(SET CMP0026 OLD)
  CMAKE_POLICY(SET CMP0045 OLD)
  CMAKE_POLICY(SET CMP0042 OLD)
  CMAKE_POLICY(SET CMP0059 OLD)
endif()

I have changed it to the following and it compiled fine:

if(CMAKE_VERSION VERSION_EQUAL "3.0.0" OR
   CMAKE_VERSION VERSION_GREATER "3.0.0")
  CMAKE_POLICY(SET CMP0026 OLD)
  CMAKE_POLICY(SET CMP0045 OLD)
  CMAKE_POLICY(SET CMP0042 OLD)
endif()
if(CMAKE_VERSION VERSION_EQUAL "3.3.0" OR
   CMAKE_VERSION VERSION_GREATER "3.3.0")
  CMAKE_POLICY(SET CMP0059 OLD)
endif()
