As said for the previous commit, this is also not good. At the end, you
should have:
depends on (BR2_PACKAGE_HAS_LIBGLES && BR2_PACKAGE_HAS_LIBEGL) || \
BR2_PACKAGE_QT5_GL_AVAILABLE
select BR2_PACKAGE_QT_OPENGL_ES if BR2_PACKAGE_QT
select BR2_PACKAGE_QT5BASE_OPENGL_LIB if BR2_PACKAGE_QT5

This comment should have been removed as part of the previous commit,
since in the previous commit, you changed the "depends on
BR2_PACKAGE_QT_GUI_MODULE" into a "select".

To be honest, I am not sure such a comment is needed. I believe it is
completely obvious for the user that a library like Qwt needs Qt.

In fact, now that I think of it, my suggestion in the previous patch to
add a dependency on libgles and libegl is wrong. This is not needed,
since qt/qt5 will already depend on them.
So, you should just have:
ifeq ($(BR2_PACKAGE_QT),y)
QWT_DEPENDENCIES += qt
QWT_QMAKE = $(QT_MAKE)
else ifeq ($(BR2_PACKAGE_QT5),y)
QWT_DEPENDENCIES += qt5
QWT_QMAKE = $(QT5_QMAKE)
endif
Thanks!
