静态运行时：
/MT: Statically link the release C runtime.
/MTd: Statically link the debug C runtime

Set the Runtime Library:
For Release builds, change the Runtime Library setting to Multi-threaded (/MT). This uses libcmt.lib.
For Debug builds, change the Runtime Library setting to Multi-threaded Debug (/MTd). This uses libcmtd.lib.

动态运行时：
executable/DLL) in your solution that will be linked together. All components must use the same /MT or /MTd 

## Understanding C Runtime Libraries in MSVC
When you build a C++ project in Visual Studio, you choose a runtime library option that determines how the C/C++ runtime (CRT) functions are handled. The key options related to libcmt.lib and DLLs are: 

/MT (Multithreaded, Static Release): Links your code with libcmt.lib. The C runtime code is statically compiled into your DLL/EXE. There is no external runtime DLL dependency for the CRT itself.
/MD (Multithreaded, Dynamic Release): Links with msvcrt.lib (an import library) which uses the msvcrt*.dll series of DLLs (e.g., msvcr120.dll, vcruntime140.dll, etc.) at runtime. This is the option used when you want your application or DLL to use a shared, redistributable runtime DLL

Location: The library file is typically located within your Visual Studio installation directory, under the appropriate architecture-specific lib folder (e.g., ...VC\Tools\MSVC\[version]\lib\[architecture]).

D:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.44.35207\lib\x64\
