The build-dependency on libqwt-dev is currently unused — the qwt driver (i.e.
the code in src/terralib/drivers/qwt/) is not built at all.

There will be also no Qt4/Qt5 conflict as the resulting binaries do not link
against any Qt at all (Qt is still used during build because upstream build
system uses qmake with Qt config). I think the severity can be downgraded to
normal, but I'll leave such a decision to the maintainers.

I don't know whether it's related, but debian/rules contains a typo in CXXFLAGS:
-I/usr/incluce/qwt (should be include).
