    Add C++11 support checking and compiler switches when building with Qt >= 5.7
    
    Qt 5.7 is the first release of Qt which makes use of C++11 features within its own codebase, including interfaces in headers. When building something with Qt 5.7, it is required to switch the compiler to the C++11 mode
