Just for consistency and because there was a need to add a fix for the Neophyte theme, I created June AppImages with very little change.
I tried to update OpenEXR as provided by Manuel V and it worked just fine on a system that had cmake at 3.12 or greater but failed in Imath (as opposed to openexr) on systems with cmake lower than 3.12.  I was OK with doing a build on these older systems by using   --without-openexr   but the configure.ac script as modified with the openexr provided patch would correctly not build openexr but still built Imath.  Tried to fix this, however I do not understand much about how the configure.ac script works.  Also, because of this, Imath in the thirdparty/src directory did not get deleted when running "make clean" either.  In addition, although I got the attached script to work standalone, I could not get it stitched correctly into configure.ac as an alternative.  Will keep trying so openexr can be upgraded next month so packages are kept as up to date as possible.  (Plus still waiting for ffmpeg 5.1?)
