Моя версия Qt 5.12.2. Я добавил DEFINES + = QCUSTOMPLOT_USE_OPENGL в мой файл .pro. Мой .pro файл показан ниже:

# The following define makes your compiler emit warnings if you use
# any feature of Qt which has been marked as deprecated (the exact warnings
# depend on your compiler). Please consult the documentation of the
# deprecated API in order to know how to port your code away from it.
DEFINES += QT_DEPRECATED_WARNINGS
DEFINES += QCUSTOMPLOT_USE_OPENGL
# You can also make your code fail to compile if you use deprecated APIs.
# In order to do so, uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000 # disables all the APIs deprecated before Qt 6.0.0

но когда я использую setOpenGl (true) для включения OpenGL, он продолжает сообщать об ошибке:
void QCustomPlot::setOpenGl(bool, int) QCustomPlot can't use OpenGL because QCUSTOMPLOT_USE_OPENGL was not defined during compilation (add 'DEFINES += QCUSTOMPLOT_USE_OPENGL' to your qmake .pro file)
Так как включить ускорение OpenGL в QCustomPlot?
