# Set up the Cppyy bindings generation. This is a customized version defined
# in boink's cmake/ dir; it uses genreflex rather than calling rootcling directly.
# I did this because I couldn't get rootcling to properly include/exclude classes
# via the LinkDef header, and I wanted to be able to use the better syntax in
# the genreflex selection XML anyhow. Also, I think this is now the recommended /
# more modern way anyhow? Code was modified from the versions cppyy distributes.
