Linking static lib causes Error

beginners
#1

I’m trying to link to a static rubberband-library https://breakfastquay.com/rubberband/ to my openframeworks project. Therefore i started a new project on Windows.

Under project properties->Linker->General->Additional Library Directories
I added the path to where the .lib file is located.

Under project properties->Linker->Input->Additional Dependencies
I added the .lib s name

Under project properties->C/C+±>General->Additional Include Directories
I added the path to where the .h file is located

This procedure worked with an empty C++ project but not with openFrameworks

My ofApp.h:
#pragma once

#include “ofMain.h”
#include “RubberBandStretcher.h”

class ofApp : public ofBaseApp{

public:
	void setup();
	void update();
	void draw();

	void keyPressed(int key);
	void keyReleased(int key);
	void mouseMoved(int x, int y );
	void mouseDragged(int x, int y, int button);
	void mousePressed(int x, int y, int button);
	void mouseReleased(int x, int y, int button);
	void mouseEntered(int x, int y);
	void mouseExited(int x, int y);
	void windowResized(int w, int h);
	void dragEvent(ofDragInfo dragInfo);
	void gotMessage(ofMessage msg);

	RubberBand::RubberBandStretcher st;

};

I have no syntax errors but if I’m trying to build the openFrameworks project, I’m getting this error:
Error C2280 ‘ofApp::ofApp(void)’: attempting to reference a deleted function

Is there a different way to link static libs in of?
Thanks for your help.

Ok, I tried a different declaration and now it is building.
“RubberBand::RubberBandStretcher *st”;

but I still dont understand what this error means
