Thanks Aurélien!

You're definitely more knowledgeable about the C++ landscape than I am.
What you're saying makes sense and sticking with gcc makes things easier
for sure.

After getting a couple of the other prereqs packaged and installed, I have
made some progress, but it has been slow.  There are lots and lots of
places in the cmake config that do checks like

if (LINUX)
 	... do a bunch of stuff
endif()

and I'm having to find all of those and either lie that OI is Linux or
attempt other adjustments.

Thanks again,

Tim
