[cmake-developers] [PATCH] fix #4168

[Alexander Neundorf]

Hi, 

the attached patch fixes bug 4168:
http://www.cmake.org/Bug/bug.php?op=show&bugid=4168

It adds the current regexps to the saved cache file and compares them when 
loading it again.
If the cache file doesn't contain this information, it is considered valid.

Plese apply.

Bye
Alex
