I can't comment on that unless / until I manage to actually build
something ;-)
I gave it another go overnight, again using /usr but without
qtchooser and without the addition of -qt5 to program names (no qt4
in that system). Did not help, I will have to try /opt again.
Meanwhile, from qt5 I acquired /usr/doc /usr/imports /usr/locale
/usr/mkspecs /usr/phrasebooks /usr/plugins /usr/qml and
/usr/translations.

How do they make the programs (e.g. qmake) available ? Are they
using qtchooser and adding -qt4 -qt5 to the program names ?

I'm starting to think that I must have changed something else in my
scripts which has somehow caused my problem. Will know for certain
after I change the scripts to use /opt/qt5. Unfortunately there
have been a lot of changes since then (my lxqt script originally did
not build qt5 because it was already installed) so I cannot just
revert one or two commits.

Yes. Without the packages labelled as required it will not proceed
(been there, done that - e.g. missing ECM, and a few weeks ago
missing the required version of ECM when I tried to put
kwindowsystem into /usr for lxqt).
I also have the optional X11, PkgConfig, XCB (of course).
