[CMake] Regex changes between cmake 2.0.6 and 2.4.2 ??

[Kris Dekeyser]

Brad,

I grabbed the binaries from the download web page last friday.

When I run the simple test below, it's fine.

---- CMakeLists.txt ----

SET(WordList "D:\\\\Temp;c:/;/root;relpath;subdir\\\\one")

MACRO(PRINT_MESSAGE DebugLevel Message)
  MESSAGE(STATUS "${Message}")
ENDMACRO(PRINT_MESSAGE)    

SET(RegexAbsoluteDir "^([a-zA-Z][:])?[/\\\\]")

#--- Make directories absolute
SET(DirList)

MESSAGE(STATUS "${Message}")
PRINT_MESSAGE(9 "WordList ${WordList}")
FOREACH(word ${WordList})
  PRINT_MESSAGE(9 "word ${word}")
  IF(${word} MATCHES ${RegexAbsoluteDir})
    PRINT_MESSAGE(9 "word ${word} matches ${RegexAbsoluteDir}")
    SET(DirList ${DirList} ${word})
  ELSE(${word} MATCHES ${RegexAbsoluteDir})
    PRINT_MESSAGE(9 "word ${word} does not match ${RegexAbsoluteDir}")
    SET(DirList ${DirList} "/MYROOT/${word}")
  ENDIF(${word} MATCHES ${RegexAbsoluteDir})
  PRINT_MESSAGE(9 "DirList ${DirList}")
ENDFOREACH(word)

---- Output ----

--
-- WordList D:\Temp;c:/;/root;relpath;subdir\one
-- word D:\Temp
-- word D:\Temp matches ^([a-zA-Z][:])?[/\]
-- DirList D:\Temp
-- word c:/
-- word c:/ matches ^([a-zA-Z][:])?[/\]
-- DirList D:\Temp;c:/
-- word /root
-- word /root matches ^([a-zA-Z][:])?[/\]
-- DirList D:\Temp;c:/;/root
-- word relpath
-- word relpath does not match ^([a-zA-Z][:])?[/\]
-- DirList D:\Temp;c:/;/root;/MYROOT/relpath
-- word subdir\one
-- word subdir\one does not match ^([a-zA-Z][:])?[/\]
-- DirList D:\Temp;c:/;/root;/MYROOT/relpath;/MYROOT/subdir\one
-- Configuring done

The weird thing is, that it fails to do the right thing in my own files. The code is almost litteraly the same, though. I really don't get it. That's why it's probably just a small and stupid error ;-)). I just can't find it.
