Major Description
The cmake_minimum_required setting for the C++ build is 2.6, but when I try to compile using cmake 2.8.2 I get an error because add_test doesn't understand the WORKING_DIRECTORY property. It turns out this was added in cmake 2.8.4. The CMakeLists.txt should either be updated to use some kind of workaround, or bump the minimum requirement to 2.8.4
