We have a winner!  Nice find Nick.  Someone can set up a build server an
set CMAKE_CXX_STANDARD accordingly without having to touch a single line
of KiCad source to at least see what happens.  Make sure you test with
older versions of Boost (1.54).  My guess is that is where the issues
will turn up.  Either Boost or wxWidgets.  Boost does provide tested
compiler builds on their website for each release so there may be some
useful information there as well.
