[CMake] FIND sub-command to the STRING command

[Tim Hütz]

I don't think that the speed-factor was important in this case. A complete CMake run takes about 25 seconds to run (in my case) and I see no influence in the processing time with my suggested patch or the regular expression sample provided by Michael. I thought that my solution is a bit more intuitive, but I don't know if this is really important for CMake. If you use the provided patch, you can do something like

PROJECT( "STRING FIND command" )
SET( TESTSTRING "This is a test" )
STRING( FIND ${TESTSTRING} "a" APOSITION )
MESSAGE( STATUS "Position of character 'a' is ${APOSITION}" )

Regards,
Tim
