Trying to compile Qt program where Qt is build from source on 18.04

which libraries I need /this/ time. The C++ ABI has changed.
Looking to see if anyone else has done this recently? Which libraries
do I have to bring along? Yes, I know about ldd and readelf and have
spent days trying this in various VMs. The problem is once you start
bringing the C++ stuff over (because the ABI has changed yet again)
you get to a point where your VM won't reboot.
Please don't suggest snappy, flatpak or one of those other new
"container" solutions. Already wasted 3+ days on snappy. It's
architecture specific and only supports building on 14.04 when it
comes to Qt, at least the deployqt tool to make an AppImage does.
Did this years ago with this very program. Built a debian which would
install on both 64-bit and 32-bit for every version from 12.04 to
15.04 including the short lived .10 and odd year versions.
I tried compiling QT with C++11 standard, but, it will no longer
compile with that standard.
The incompatible ABI is the real killer.
It is more than one program so the hack of a shell script using
LD_LIBRARY_PATH would bring considerable difficulty.
Appreciate insights.
