It's right here:

        http://svn.boost.org/trac/boost/browser/sandbox-branches/boost-cmake/ 
boost_1_34_0/tools/wave/CMakeLists.txt

boost_add_executable is used in several places throughout the Boost  
CMake branch, including the regression testing.

It sounds like an error in the Boost CMake code. A few quick questions:
        - Are you using the latest from https://svn.boost.org/svn/boost/ 
sandbox-branches/boost-cmake/boost_1_34_0 ?
        - Which version of CMake are you using?
        - Do you recall which CMake options you changed?

The Boost CMake work is still in a rather preliminary state, but it  
typically builds Boost out of the box without this kind of problem.
