cmake error on Ubuntu 13.10

[Patryk Laurent]

Hello,

When I try to use cmake on Ubuntu 13.10, as per http://wiki.gnustep.org/index.php/GNUstep_under_Ubuntu_Linux, I get the following error:

CMake Error at CMakeLists.txt:5 (add_llvm_tool_subdirectory):
  Unknown CMake command "add_llvm_tool_subdirectory”.

I’ve included the full output of the cmake command below.  The version of cmake installed with apt-get in Ubuntu 13.10 is 2.8.11.2.  Adding cmake_minimum_required(VERSION 2.8.8) to the top of CMakeLists.txt did not seem to help.

Any suggestions on how to get this working would be most welcome.

Thank you,

Patryk

The full output of the cmake command is:

patryk@paklbox:~/llvm/tools/build$ cmake --version
