I compiled a table of configure feature test results for various
versions of Qt available on Debian and Ubuntu stable releases, and
included your 4.8.7 results. I hope this is useful:
https://gitlab.com/snippets/1834909
I didn't have a Qt 5.4 readily available, but you can see that 5.5 is
the first Qt version with QOpenGLWidget and QOpenGLContext for working
offscreen rendering. I expect the same results with 5.4.
If we drop checking for Qt 4 (only look for Qt5Core, not QtCore), and
drop checking for QGLWidget (only look for QOpenGLWidget and require
that for AMCOND_BUILD_QT_GRAPHICS), the table shows that would eliminate
the need for more than half of these feature tests.
If we come to a consensus on this I am happy to do the work and/or test
this big change, and I now have test environments set up for each of
these Qt versions.
