Copied and pasted wrong one sorry.

RHEL7 comes with GCC 4.8, which isn't supporting using syntax, you can rewrite it

    case QEvent::LocaleChange: {
-       if (const QLocale locale = AppSettings().locale(); locale == AppSettings::defaultLocale())
+       const QLocale locale = AppSettings().locale();
+       if (locale == AppSettings::defaultLocale())
            AppSettings::applyLocale(locale);
        break;
    }

Thanks, that worked great. Now the only problem is I'm getting the following message:
Cannot launch daemon, file not found or permissions invalid
Thank You.

Saw the following in /var/log/messages
dbus[3219]: [system] Activated service 'dev.jonmagon.kdiskmark.helperinterface' failed: Cannot launch daemon, file not found or permissions invalid

[lphabc]

Found it. kdiskmark_helper was in /usr/libexec where the /usr/share/dbus-1/system-services/dev.jonmagon,kdiskmark.helperinterfaces.service was pointing to /usr/local/libexec/kdiskmark_helper

I made a link for /usr/libexec/kdiskmark_helper to /usr/local/libexec/kdiskmark_helper

Interesting. CMakeLists.txt has not been edited? It uses KDE_INSTALL_LIBEXECDIR for kdiskmark_helper installing and dev.jonmagon.kdiskmark.helperinterfaces.service configuring, should be the same.

[lphabc]

No hasn't been changed and has DESTINATION ${KDE_INSTALL_LIBEXECDIR}
