[Enhancement]: G'MIC is not correctly included

[kenwenzel]

What changes would you like?

When checking the source code of this package it seems to be the case that G'MIC is included as a gimp plug-in but it is not available. I had to manually install the following G'MIC version: https://gmic.eu/files/linux/gmic_3.3.5_gimp2.10_ubuntu20-04_focal_amd64.zip

Versions for a newer Ubuntu variant depend on Qt 5.15 which is not available in this snap package.

Is it possible to directly include G'MIC or am I missing something?

Any extra information?
