That's not installed anywhere else. But the thing is, i found this problem on xubuntu 18.04 at Qt 5.9. But i tried this on Ubuntu 18.04 at Qt 5.9 and it works without typing
-L/usr/lib
i think i have to use-L/usr/libfor me...
And i found my solution. Like
LIBS += -L/usr/lib -llibraryname
Thanks all of you...
