#### Testing the changes
- I tested the changes in this PR: **YES**

#### Local build testing
- I built this PR locally for my native architecture, x86_64-glibc
-  Cross build - aarch64

Disabling the tests for *-musl (https://github.com/AcademySoftwareFoundation/openexr/issues/1556)

Currently failing, because this templates are broken: 

- [x] hugin (fails because it needs vigra)
- [x] openimageio (checksum wrong, fixed)
- [x] vigra #46829
