WIN32_EXECUTABLE ---------------- Build an executable with a WinMain entry point on windows. When this property is set to true the executable when linked on Windows will be created with a WinMain() entry point instead of just main(). This makes it a GUI executable instead of a console application. See the :variable:`CMAKE_MFC_FLAG` variable documentation to configure use of the Microsoft Foundation Classes (MFC) for WinMain executables. This property is initialized by the value of the :variable:`CMAKE_WIN32_EXECUTABLE` variable if it is set when a target is created.
