Summary:                    Does not use EXE subsystem when building GUI
application with GCC for Windows
Description: 
When building with GCC for Windows, in makefiles generated by CMake, there is no
instruction to set a subsystem. The default subsystem is console, when building
a console application, it does not matter. But when I make a GUI program, it
becomes console, too, and shows a console window in background when running.

For example, if user configured to use Qt with QtGui module (FindQt*.cmake), the
module should add the following option to gcc command line
(CMAKE_EXE_LINKER_FLAGS): -Wl,-subsystem,windows.

Steps to Reproduce: 
FindQt(REQUIRED)

Use GCC to build an application for Win32.

Additional Information: 
Workaround:

IF( WIN32 )
  SET( CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -Wl,-subsystem,windows"
)
ENDIF()
