1、有些设置 可能这里在设置了，到别的地方(例如换了一个机子) 又要设置，这样的话 在不熟练的时候 手动敲进去会比较慢，这里 先记录下来 以后要用 直接复制就行了
2、Qt5.9.8 vs2017 ：Tools > Options > C++ > Code Model > Clang Code Model > Manage
"Diagnostic Configuration" 默认选中的是 "Clang-only checks for almost everything [built-in]"，然后 我将它 "Copy..."一下，名字命名为"Clang-only checks for almost everything (CopyByZC)"
于是 它现在的内容为：
-Weverything -Wno-c++98-compat -Wno-c++98-compat-pedantic -Wno-unused-macros -Wno-newline-eof -Wno-exit-time-destructors -Wno-global-constructors -Wno-gnu-zero-variadic-macro-arguments -Wno-documentation -Wno-shadow -Wno-switch-enum -Wno-missing-prototypes -Wno-used-but-marked-unused
然后 再在 "Diagnostic Configuration"中选择 "Clang-only checks for almost everything (CopyByZC)"
3、后加的内容也记录下来，方便以后直接复制（而不用一直重复的手动一一敲入）
