Can't use OSG with GDAL on Windows - c++

Question

I work on Windows 10 x64
IDE: QtCreator 4.8.0 Based on Qt 5.12.0 (MSVC 2015, 32 bit)
Content of my .pro file is at the very bottom if it's needed.
There is a minimal OSG sample (main.cpp):
#include <osgDB/ReadFile>
#include <osgViewer/Viewer>
#include <ogrsf_frmts.h>
int main(int argc, char *argv[]) {
// OGRPoint p; //breakpoint 1
osg::ref_ptr<osg::Node> root = osgDB::readNodeFile("../resourses/cessna.osg"); //breakpoint 2
osgViewer::Viewer viewer;
viewer.setSceneData(root.get());
return viewer.run();
}
In the code above you can see, where i set breakpoints.
So:
In case with commented OGRPoint p;:
It compiles, runs, stops on "breakpoint 2" and when i go forward it shows the airplane (model "cessna.osg"). This is correct behavior.
In case with uncommented OGRPoint p;:
It compiles, runs and ignore both breakpoints. It doesn't show anything. As if i had nothing in my main. If i do it on Linux, then it works fine. Why does it can happen?

Answer 1

Problem was that the library needed libgdal-20.dll to work. I didn't specify the path to the .dll. So i resolved this problem by copiyng the .dll file into folder with binaries. Now it works fine.
