[CMake] FIND sub-command to the STRING command

[Tim Hütz]

Hey,

mhh, yeah, thats a good idea. Ok, I'll use this for doing a "STRING( FIND ...)" :) It was just an idea to share this patch with you, but you're right. Its easier doing this with regular expressions.

Regards,
Tim

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. I don't know if this could be helpful for anymore else, hence I attached a patch with this extension to CMake. I'm happy for any comments.
