1、有些設置 可能這里在設置了，到別的地方(例如換了一個機子) 又要設置，這樣的話 在不熟練的時候 手動敲進去會比較慢，這里 先記錄下來 以后要用 直接復制就行了
2、Qt5.9.8 vs2017 ：Tools > Options > C++ > Code Model > Clang Code Model > Manage
"Diagnostic Configuration" 默認選中的是 "Clang-only checks for almost everything [built-in]"，然后 我將它 "Copy..."一下，名字命名為"Clang-only checks for almost everything (CopyByZC)"
於是 它現在的內容為：
-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"中選擇 "Clang-only checks for almost everything (CopyByZC)"
3、后加的內容也記錄下來，方便以后直接復制（而不用一直重復的手動一一敲入）
