[Cmake] case sensitive string matching ?

[Bill Hoffman]

The MATCHES uses a regular expression, not a wild card.
Here are the meanings of the metacharacters in the cmake regular expression:


 *  ^        Matches at beginning of a line
 *
 *  $        Matches at end of a line
 *
 * .         Matches any single character
 *
 * [ ]       Matches any character(s) inside the brackets
 *
 * [^ ]      Matches any character(s) not inside the brackets
 *
 *  -        Matches any character in range on either side of a dash
 *
 *  *        Matches preceding pattern zero or more times
 *
 *  +        Matches preceding pattern one or more times
 *
 *  ?        Matches preceding pattern zero or once only
 *
 * ()        Saves a matched expression and uses it in a  later match
 

So "A*" means, match 0 or more times, and "ab" matches 0 times so, it is a match.

What you want is this:

IF("ab" MATCHES "a+")
 MESSAGE("++++   ab matches a* ")
ENDIF("ab" MATCHES "a+")


IF("ab" MATCHES "A+")
 MESSAGE("++++   ab matcheses A* ")
ENDIF("ab" MATCHES "A+")
