How do I match a literal '+' in a regular expression?
This matches in grep (because it doesn't treat '+' as a special
character), but CMake says it can't compile it (for good reason if '+'
is a special character).
"g++.*$"
I tried escaping the '+', but that didn't work either:
"g\+\+.*$"
syntax error, unexpected cal_ERROR, expecting $end (3), when parsing
string "g\+\+.*$"
I'm trying to match string g++, g++-4.0 etc.
Thanks,
James
