<br>
I used the path of least resistance because as far as I could tell
boost only let you build one or the other and in my case it was
the python3 boost api. In the end caffe was working and all the
python3 tests with the Movidius SDK pass (which use python3).<br>

Conditionally creating the link when building python3
support into<br>
boost is all that is needed.<br>
