I have a package which indirectly calls qmake (from Qt5).  Is there a
way to inject the standard build flags using environment variables, or
do I have to patch the invocation of the qmake command itself to pass
the flags, similar to what %{qmake_qt5} does?

%{qmake_qt5} already does that in general.   it will use any existing
values for environment variables CFLAGS, CXXFLAGS, LDFLAGS.

In short, set CFLAGS, CXXFLAGS, and/or LDFLAGS prior to calling
%{qmake_qt5}

Oh, *indirectly* calls qmake, that may be trickier.  Which package?

I doubt that setting the QMAKE variable works; the required shell quoting would be pretty horrible (three or four levels).

I found some qt(4), examples of using a qmake wrapper, but the principle is
the same, one is:
https://marc.info/?l=fedora-extras-commits&m=145585036023552&w=2

I don't want to copy this solution in the dozen or so packages which need this (and I probably would have missed QMAKE_STRIP). Surely it would make sense to provide a generic solution?

Thanks,
Florian
