Enabling the OTB_USE_QWT option after adding libqwt-dev to the build
dependencies and dependencies of libotb-dev, the build fails in Debian
unstable because the Qwt version is not supported:

-- Found Qwt: /usr/lib/libqwt.so (found version "6.1.2")
CMake Error at Modules/ThirdParty/Qwt/otb-module-init.cmake:4 (message):
  Only Qwt 5 is supported.  Found version 6.1.2

Changing the dependency to libqwt5-qt4-dev resolves that, but won't be
very future proof.

Qwt 5 is likely to be removed from Debian and Ubuntu in the future, it's
maintainer doesn't have time for the Qwt packages any more, so the OTB
team should really start supporting Qwt 6 which QGIS uses too so only a
single version needs to be adopted by others in Debian. I talked about
this with the Qt/KDE maintainers before, and we'll likely move the Qwt 6
package to that team after the stretch release when the next release
critical bug affects the qwt package.

In the mean time I'm updating the otb package to also build the
monteverdi binary package, but it's going to need some work to get in shape.

Kind Regards,

Bas
