Summary:                    Extending the STRING command with a FIND sub-command
Description: 
Recently I was searching for a CMake option to get the position of a single
character (first appearance) out of a string. As I found nothing which could
provide me an easy solution, I pulled the latest development version and added a
FIND sub-command to the STRING command.

The attached patch supports a forward search (finds the first occurrence of the
substring) and a reverse search (which finds the last occurrence of a
substring).

Here is a sample how the sub-commands works:

-----

project( "STRING FIND command" )
cmake_minimum_required(VERSION 2.8)

set( TESTSTRING "This is a test and here is another test." )
string( FIND ${TESTSTRING} "a" APOSITION )
string( FIND REVERSE ${TESTSTRING} "a" APOSITIONREV )
message( STATUS "Firt position of character 'a' (8) is ${APOSITION}" )
message( STATUS "Last position of character 'a' (27) is ${APOSITIONREV}" )

-----

I've already discussed this sub-command on the CMake mailing list
(http://www.cmake.org/pipermail/cmake/2011-February/042521.html).

Maybe, this would be a nice feature for one of the next CMake releases.

Best regards,
Tim
