Unable to run CPP unit tests

[sumau]

Initially raised in #438

I can't run the unit tests. I tested using this demo and that ran fine.

I followed these steps:

1. clone googletest in tick: git clone https://github.com/google/googletest.git (cd googletest && mkdir -p build && cd build && cmake .. && make && sudo make install) which succeeded after adding sudo to make install

2. python3 setup.py build_ext --inplace cpptest This builds the CPPtests but fails when trying to run the CPPtests with following error:
