I think that the qmake code could be adapted to issue such warnings.
I will have a look if nobody beats me to it.
To be frank, I'd love to be able to dispose of most of the stuff in
qt.m4 and rely on qmake only. I have to say though that the current
code is mysterious to me, for example when it come to percent
variables.
There is nothing special about naming percent a variable and that is
simply done because the fake custom target is named "%". See here:
https://doc.qt.io/qt-6/qmake-advanced-usage.html#adding-custom-targets
Without those "percent" variables, if you try to extract the qmake's
variable INCPATH you would obtain:
$ make -s -f Makefile INCPATH
make: *** No rule to make target 'INCPATH'. Stop.
Instead, with the "percent" variables the contents of the variable
INCPATH is echoed to screen.
