GNU Scientific Library + QT 5.2 win7x64. What causes error 0xc0000135 on startup?

Question

Qt

There was a need to use GSL on qt under windows 7x64. GSL taken from here Gsl for Windows .
When running a simple debugging application, it crashes with error 0xc0000135.
Including libraries using QtCreator

win32: LIBS += -L$$PWD/lib/ -lgsl
INCLUDEPATH += $$PWD/gsl
DEPENDPATH += $$PWD/gsl
win32:!win32-g++ PRE_TARGETDEPS += $$PWD/lib/gsl.lib
else:win32-g++: PRE_TARGETDEPS += $$PWD/lib/libgsl.a

I'm trying to perform a simple one-dimensional wavelet transform

#include "mainwindow.h"
#include <QApplication>
#include <stdio.h>
#include <vector>
#include "gsl_wavelet.h"
int main(int argc, char *argv[]){
    QApplication a(argc, argv);
    MainWindow w;
    w.show();
    const int SIGNAL_LENGHT = 2650;
    double data[SIGNAL_LENGHT];

    freopen("inp.txt","r",stdin);
    for (int i=0;i<SIGNAL_LENGHT;i++){
        scanf("%d",data[i]);
    }

    gsl_wavelet *wavelet;
    gsl_wavelet_workspace *work;

    wavelet = gsl_wavelet_alloc(gsl_wavelet_daubechies,4);
    work = gsl_wavelet_workspace_alloc(SIGNAL_LENGHT);

    gsl_wavelet_transform_forward(wavelet, data, 1, SIGNAL_LENGHT, work);

    gsl_wavelet_free (wavelet);
    gsl_wavelet_workspace_free (work);
    return a.exec();
}

Part of the example is taken from here .
QtCreator says the application has crashed before entering main() with code 0xc0000135.

We look at the project's Path variable, most likely it does not see the GSL
UPD binary. By the way, fresh GSl for vin can be found here
