Thank you! 

Builds now, without further problems.
Excited to check it out!

Regarding Qt: 

Is that flag actually strictly necessary? 
I had thought the build process would discover 
that there are no Qt libs installed and skip 
the dependency...

Thanks for providing the list of required
libraries - that should help avoid much 
trial-n-error. Unfortunately, I can't seem 
to find them, or equivalent, for my own
system (Debian/Ubuntu/Mint based). I did 
not dig too deep, but I can't find any 
"lib64qt5..." libs, only "libqt5*", but
those don't have -dev or -devel variants.

Strange. Maybe I need to add a non-standard
repository. (No need to research that, but I
find it odd.)

But mostly: Thanks again.
Excited to check out gp6! ;-)

Best,
