Как исправить ошибки QOpenGLShader: Unable to open file «shaders/vertexshader1.vsh» QOpenGLShader: Unable to open file «shaders/fragmentshader1.fsh»?

Всем доброго времени суток, скажите пожалуйста почему при запуске программы qt выдает что шейдеры(вершинный и фрагментный) не открываются и как это исправить?
вот мои исходники:
