Incompatibility with openexr 3

[mulliganaceous]

Describe the bug
After running the cmake on Arch Linux, and installing the missing openexr dependency, I learned that FragM is incompatible with openexr 3. I have to manually build openexr 2.5.

Desktop (please complete the following information):

• OS: Arch Linux
• Gfx card: Nvidia 3050 mobile
• Driver version: 570.86.16

Additional context
For visualizing more hyperbolic honeycombs.

the win build will use OpenEXR 3 however the linux build uses 2.5 because that is what got installed on my dev system

if you are not comfortable with editing the cmakelists.tx file then installing oexr 2.5 should work.

I plan to move to Qt6 and OpenEXR3 soon.

That is good news! I am also having trouble running in KDE Plasma.

KDE Plasma has a number of issues. If your machine is left running 24/7 (like mine) then some of the plasma widgets/scripts will eventually go off the deep end and start consuming 100% CPU and due to mem leaks will also consume 100% ram. I really like KDE+plasma and it really bothers me that these bugs have been around for a LONG time, 0-day?

So far I have heard no complaints from users of other desktops so I blame plasma (for now).

Current dev box OS installs OpenEXR 2.2 and requires the Extra_CMake_Modules package and modules path to locate the FindOpenEXR.cmake file

if your OS installs this file in the appropriate place then the lines in cmakelists.txt for ECM can be safely removed.

will try making it "not required"...
