How to add external lib (libstatgrab.so) to qtcreator?

[PawlosCK]

Hello

How can I add external lib (libstatgrab.so.10.0.0) to project?
I want to add libstatgrab (http://www.i-scream.org/libstatgrab) to my project, but I can't. I built lib from source code.

I tryed to add to ".pro" file this line
LIBS += -L/home/pawel/Moje_Dokumenty/Programowanie/BibliotekaQT/libstatgrab-test/libs/ -llibstatgrab
but doesn't work. I tryed to add this path to LD_LIBRARY_PATH, but it doesn't work too.
What I can do?

I create simply project to test it. I modified only one file

#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <statgrab.h>
#include <helpers.h>
MainWindow::MainWindow(QWidget parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
sg_init(1);
/ Drop setuid/setgid privileges. */
// if (sg_drop_privileges() != SG_ERROR_NONE)
// sg_die("Error. Failed to drop privileges", 1);
ui->setupUi(this);
}
MainWindow::~MainWindow()
{
delete ui;
}

Linker shows me
:-1: error: cannot find -llibstatgrab
:-1: error: collect2: error: ld returned 1 exit status

Replace -llibstatgrab with -lstatgrab in your .pro file (lib prefix is added automatically, so you should not use it)
