  13 Controls if the project should be built in multi-threaded mode. This feature
  14 does not necessary change code generation in the compiler, but it causes the
  15 compiler to link to additional or different runtime libraries, and define
  16 additional preprocessor symbols (for example, `_MT` on Windows and `_REENTRANT`
  17 on Linux). How those symbols affect the compiled code depends on the code
  18 itself.
