在Qt Creator中禁用项目范围的编译器警告（使用MSVC时）
问题描述：
我想停用特定的警告，例如 C ++警告C4018：'<'：signed / unsigned mismatch ，但是项目范围。
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?
答
将以下行添加到您的PRO文件中：
Add the following line to your PRO file:
QMAKE_CXXFLAGS += /wd4996
