Enabling Checks for this warning class are disabled by default. To enable them, add the following WARNING_FILTER rule to the project configuration file. 
WARNING_FILTER += allow class="Use of system"

Resolution

int system(const char *command)
int _wsystem(const wchar_t *command)

When you are warned about a use of system() or _wsystem(), make sure that make sure that any executable in the command argument is specified with an absolute path name from a trusted source.

Once you are satisfied that these conditions hold, you can change the warning state to Suppressed.
