"grep -Rs QtXml Modules/"
grep only shows  Modules/ThirdParty/Qt4/otb-module-init.cmake
try deactivating it and see how the build goes tomorrow

Bug fixed. We might want to check the behavior of the nu classification as there is a lot of value that are not acceptable. Either it is the model then it's okay or it's a method that does a strange manipulation changing its value.

HasValue() in those cases is always true, because SetFromFileName always
succeeds now.

ENH: Check of c++11 support and module declaration of c++11 requirements are not needed anymore in otb configuration

ENH: try to compile mapla and monteverdi as shared libs (don't find the reason why its always build as static libs)

- update CMake minimum required version
- set the C++ standard
- set otb::Image constructor to =delete to test
