[CMake] IF(... MATCHES WIN32) weird behavior

[Filipe Sousa]

Why this matches

SET(arg "WIN32")
IF("${arg}" MATCHES "WIN32")
  MESSAGE(STATUS ":)")
ELSE("${arg}" MATCHES "WIN32")
  MESSAGE(STATUS ":(")
ENDIF("${arg}" MATCHES "WIN32")

C:\_builds\testes>cmake -G"NMake Makefiles" c:\_projects\testes
-- :(
-- Configuring done
-- Generating done
-- Build files have been written to: C:/_builds/testes

and this fails?

SET(arg "WIN3")
IF("${arg}" MATCHES "WIN3")
  MESSAGE(STATUS ":)")
ELSE("${arg}" MATCHES "WIN3")
  MESSAGE(STATUS ":(")
ENDIF("${arg}" MATCHES "WIN3")
                                
C:\_builds\testes>cmake -G"NMake Makefiles" c:\_projects\testes
-- :)                           
-- Configuring done             
-- Generating done              
-- Build files have been written to: C:/_builds/testes

C:\_builds\testes>cmake --version
cmake version 2.1-20050531

I don't see the problem under linux
