Summary: Regex does not match last parenthesis if parenthesis
is part of character set.
Description:
The aim is to extract the content between two parentheses.
Example:
from the string "FUNCTION(ARG1, ARG2, ARG3) //COMMENT",
I want to extract "ARG1, ARG2, ARG3".
The normal behavior of CMake is to return all the matched characters.
In the case of a paranthesis as matched character, it does not return the
closing parenthesis.
For reference, I have added the expected behavior by replacing all parentheses
with underscores.
Steps to Reproduce:
cmake_minimum_required(VERSION 3.3)
#Do the match with parentheses
string(REGEX MATCH "FUNCTION\(([^\)]+)\)" ARGUMENT "FUNCTION(ARG1, ARG2, ARG3)
//COMMENT")
message(STATUS "Result of regex match with parentheses: ${ARGUMENT}")
#Redo the match with the parentheses replaced with underscores
string(REGEX MATCH "FUNCTION_([^_]+)_" ARGUMENT "FUNCTION_ARG1, ARG2, ARG3_
//COMMENT")
message(STATUS "Result of regex match with underscores: ${ARGUMENT}")

The result of the regex match with parentheses should be
FUNCTION(ARG1, ARG2, ARG3)
