cmake error when building Boost unit tests - c++

Question

I'm working through this tutorial, using VS2012 on a c++ project generated by cmake 3.0.2.
http://help.exercism.io/getting-started-with-cpp.html
I have a series of boost unit tests that check whether the correct message is returned when given an input. Most of the tests work, but strangely, some cause a build error.
Error 1 error MSB3073: The command "setlocal

if %errorlevel% neq 0 goto :cmEnd

It looks like boost tests are working like they should. I needed to check the output window rather than look at build errors.
