get_clang_version does not parse the version correctly

[NightEule5]

When building ogc-sys, Clang is unable to find system libraries like stdlib.h. I did some probing, and found that get_clang_version outputs 16.0.6 instead of the expected 16, leading to an invalid /usr/lib/clang/.../include path.

The problem is with the regex:

let regex = Regex::new(r"(?m)\d+(\.\d+)+").unwrap();
let result = regex.captures(first_line).unwrap().get(0);

Capture group 0 refers to the whole match, which includes the (\.\d+)+ part. Perhaps you meant:

let regex = Regex::new(r"(?m)(\d+)(\.\d+)+").unwrap();
let result = regex.captures(first_line).unwrap().get(1);

Or, using non-capturing groups:

let regex = Regex::new(r"(?m)\d+(?:\.\d+)+").unwrap();
let result = regex.captures(first_line).unwrap().get(0);
