[CMake] Problem with string( FIND xxx ) in cygwin

[Renato Utsch]

I am using CMake 2.8.4 in cygwin (the version that comes with
setup.exe), but it doesn't recognize the string( FIND <...> ) command,
although it works in linux and windows very well.

Is there any library I need to install in cygwin to make this work or
the build from them is not working?
