[Interest] How best to turn on "-std=gnu++11" when using qmake to build a project?

[Alexandre Pretyman]

Hi!

For each project you can check out out QMAKE_CXXFLAGS and QMAKE_LFLAGS
on http://qt-project.org/doc/qt-5.0/qtdoc/qmake-variable-reference.html

For global I guess you can edit the mkspecs for you compiler

Best regards,
