This is also being used in src:explosive-c4 now and the approach breaks
cross compilation. Please stop doing this, we'll have to touch all of
these.
Still the use case is real and we need a better way to build packages
with qmake6. I was talking with Sune and Lisandro on IRC and their
consensus seems to have been that qtchooser and QT_SELECT are dead and
should not be used for Qt6. They suggested that we add add a new
--buildsystem to debhelper. We already have qmake_qt4 and qmake, why not
have qmake6? While changing QT_SELECT from qt5 to qt6 would be
convenient, changing it to "dh $@ --buildsystem qmake6" is easy enough,
no? The qmake6 build system can reuse qmake just like qmake_qt4 and
doing it that way immediately makes cross compilation just work (since
we already have <triplet>-qmake6). Lisandro requested naming it qmake6
rather than qmake_qt6. Even though this breaks consistency with earlier
use in debhelper, the similarity to how upstream calls it more
important.
Salvo and Alexandre, do you second this?
Can I also get some ack from Qt maintainers such that we can move
forward in consensus?
