使用C ++功能在系统路径中进行模式匹配

Question

I am working on Installation of particular Qt based Windows GUI application, which needs DLLs to be placed in the PATH system environment variable. For placing I could somehow manage to append Installation_path to PATH . But while uninstallation of my application I want to search for where my installation path is and then I've to remove those and put normal path as usually without modifying it. Is a regex my companion or any other way in doing this?

PS I cannot use boost lib.

You don't need a regex, all you need to do is locate a substring, case-insensitive. Since you have Qt, use indexOf
