While looking into the CI failure, I noticed that xlint flags qmake_default_version as a custom variable, even though this variable is already part of the qmake build-helper workflow.

qmake_default_version is referenced in:

• the qmake5.sh and qmake6.sh build-helpers
• the sourcepkg.sh environment setup script

However, it does not seem to be recognized by xlint’s variable whitelist, which results in a warning when it is set in the template.

What would be the preferred way forward here?

• Add qmake_default_version to xlint’s recognized variables
• Keep the template as-is, since this variable has historically been used this way
• Or adopt another approach that maintainers consider more appropriate

I’m happy to adjust the template or make a follow-up modification based on the preferred approach.

if it's used by a build style, it should be in xlint

Thanks for confirming. I’ll follow up with a PR to update xlint to recognize qmake_default_version.
