Summary:                    string(REGEX REPLACE) doesn't correctly anchor regex
with ^ for multiple matches
Description: 
string(REGEX REPLACE) doesn't seem to anchor multiple matches correctly with the
^ symbol - subsequent matches seem to be anchored at the start of the next
substring.

Steps to Reproduce: 
Run the following cmake script:

-----------
string(REGEX REPLACE "^([^-]*-)" "@\\1#" output "foo-1.2-3")
message(STATUS "\"${output}\"")
-----------

Output is

-- "@foo-#@1.2-http://www.cmake.org/Bug/view.php?id=3"

so the pattern has matched twice, whereas it should only match the input string
once at the start - the expected output is

-- "@foo-http://www.cmake.org/Bug/view.php?id=1.2-3"
