cmake fails to build makefile because of missing source in sourcetree

[GoogleCodeExporter]

What steps will reproduce the problem?
1. checkout source code of v2.3.1 from svn
2. run "cmake ." in v2.3.1/Box2D
3. See it fail

What is the expected output? What do you see instead?

cmake should generate a functional makefile for make to build the project

What version of the product are you using? On what operating system?

v2.3.1 Fedora 20 x86_64, with glui-devel and freeglut-devel installed.

Please provide any additional information below.

The build fails because it depends on having source code in the source tree 
which isn't part of the project -- this includes freeglut, glui and 
Framework/Render.cpp (at least).

Running cmake on Box2D with no modifications provide the following output:

After having removed the add_subdiretory entries in CMakeLists.txt for glui and 
freeglut, running cmake on Box2D, it outputs the following:

I'm not supporting CMake anymore. Would you be willing to provide a patch?

I'm having the same trouble. Fresh svn checkout of 2.3.1, running cmake in the 
build directory:

If cmake isn't supported anymore, how are we supposed to build the files? 

I tried adding the box2d files to my project anyway and xcode errors out with 
dozens of language syntax errors:
