Не компилируется проект с QCustomPlot

Здравствуйте.

У меня был рабочий проект с QCustomPlot. Я заархивировал и разархивировал проект. После этого при компиляции выдает ошибки:
Сообщение:
C:\Qt\project\build-MyCandleSrick-Desktop_Qt_5_9_2_MinGW_32bit-Debug\debug\qcustomplot.o:-1: In function `ZN19QCPPaintBufferGlFbo5clearERK6QColor':
Ошибки:
C:\Qt\project\MyCandleSrick\qcustomplot.cpp:909: ошибка: undefined reference to `_imp__glClearColor@16'
C:\Qt\project\MyCandleSrick\qcustomplot.cpp:910: ошибка: undefined reference to `_imp__glClear@4'
collect2.exe:-1: ошибка: error: ld returned 1 exit status
Скажите пожалуйста в чем причина и как исправить?

Ошибке в файле qcustomplot.cpp в функции

void QCPPaintBufferGlFbo::clear(const QColor &color)
{
  if (mGlContext.isNull())
  {
    qDebug() << Q_FUNC_INFO << "OpenGL context doesn't exist";
    return;
  }
  if (!mGlFrameBuffer)
  {
    qDebug() << Q_FUNC_INFO << "OpenGL frame buffer object doesn't exist, reallocateBuffer was not called?";
    return;
  }
  if (QOpenGLContext::currentContext() != mGlContext.data())
    mGlContext.data()->makeCurrent(mGlContext.data()->surface());
  mGlFrameBuffer->bind();
  glClearColor(color.redF(), color.greenF(), color.blueF(), color.alphaF());
  glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
  mGlFrameBuffer->release();
}

    Перенес код в другой проект и все заработало. Вы не знаете, в чем баг с архивацией?

      Скорее дело не в архивации, а в кривом проекте. Но причину в данном случае проблематично назвать.
