Comment:
Just a small note. The `cdk` dependency from invisible-mirror.net fails sometimes with this message below:

```
=> textadept-11.2_1: fetching distfile 'cdk-5.0-20200923.tgz'...
https://invisible-mirror.net/archives/cdk/cdk-5.0-20200923.tgz: Operation timed out
=> ERROR: textadept-11.2_1: failed to fetch cdk-5.0-20200923.tgz.
Error: Process completed with exit code 1.
```

It used to go pretty well for the first few builds, but then [this used to happen](https://github.com/void-linux/void-packages/pull/29666#issuecomment-803646589). This is probably because the mirror site has some abuse detection in place and blocks later requests.

I've changed the dep url to be from `https://github.com/orbitalquark/textadept-build` so that this doesn't happen. The advice came from [the project itself](https://github.com/orbitalquark/textadept/discussions/78#discussioncomment-513052). The build doesn't fail now after this change.
