Hi Alex,

I have used this system_name because I found this file:

claus-kleins-macbook-pro:Platform clausklein$ grep -iw mingw *.cmake
Windows-gcc.cmake:SET(CMAKE_EXTRA_LINK_EXTENSIONS ".lib") # MinGW can  
also link to a MS .lib
Windows-gcc.cmake:IF(MSYS OR MINGW)
Windows-gcc.cmake:ENDIF(MSYS OR MINGW)
Windows-gcc.cmake:IF(MSYS OR MINGW)
Windows-gcc.cmake:ENDIF(MSYS OR MINGW)
WindowsPaths.cmake:  # MinGW (useful when cross compiling from linux  
WindowsPaths.cmake:# mingw can also link against dlls which can also  
be in /bin, so list this too
claus-kleins-macbook-pro:Platform clausklein$ ls -l $PWD/Windows-gcc*
-rw-r--r--  2 root  admin  4097 13 Nov 19:32 /opt/local/share/ 
claus-kleins-macbook-pro:Platform clausklein$

Note: I was crosscompiling for MinGW
