Disable a compiler-warning project-wide in Qt Creator (when using MSVC)

Question

I want to disable a particular warning, such as C++ warning C4018: '<' : signed/unsigned mismatch, but project-wide. What do I need to put in my .pro file to achieve that effect?

Add the following line to your PRO file:

QMAKE_CXXFLAGS += /wd4996
