qmlinterfacegenerator does not find "license"

When Qt For MCUs offered Linux support, I decided to integrate Qul build to our main CI. But then things got interesting. On my local host (Fedora 34) build is performed smoothly without errors, but when it is built on CI node (Ubuntu 20.04) I get these license problems. It appears that they are coming from qmlinterfacegenerator binary tool.

I'm using custom board, not from the provided ones.

What dependencies could cause this behavior?

Update: I tried to remove whole QtForMCUs installation directory and leave the source only, thinking that it could contain some license files. Unfortunately local builds still complete.
