Summary0014336: REGEX REPLACE does not give correct results for a left anchor (^) combined with careted brackets
Description# Test code to show the issue.
set(filename "whatever")
string(REGEX REPLACE "(^[e])" "/\\1" CATALOG_filename "${filename}")
message(STATUS "filename=${filename}")
message(STATUS "CATALOG_filename=${CATALOG_filename}")
string(REGEX REPLACE "(^[^e])" "/\\1" CATALOG_filename "${filename}")
message(STATUS "filename=${filename}")
message(STATUS "CATALOG_filename=${CATALOG_filename}")

The first REGEX REPLACE gives a correct result (no match because of the anchor
so no replacement is done) while the second REGEX REPLACE produces an incorrect result (anchor ignored until the "e" is hit in whatever).
Steps To ReproduceRun the above code using cmake -P. The results are

-- filename=whatever
-- CATALOG_filename=whatever
-- filename=whatever
-- CATALOG_filename=/w/h/a/tever

That last one should be

-- CATALOG_filename=/whatever

because the anchor should limit the match to just the first character (so long as that first character is not an "e" as in this case) so the "/" should be prepended only to the first character.
TagsNo tags attached.
