phpversion('imagick') is returning `@PACKAGE_VERSION@` instead of the actual version number

[erezhod]

I have been using FROM webdevops/php-apache-dev:7.4-alpine as my Docker entry for a year now and it contained Alpine v3.13. Lately I have reset my Docker images completely to start fresh and the php-apache-dev:7.4-alpine image is now using Alpine v3.14.

The problem with this version, is that I am using a library named TCPDF and it contains the following code:

public static function objclone($object) {
    if (($object instanceof Imagick) AND (version_compare(phpversion('imagick'), '3.0.1') !== 1)) {
        // on the versions after 3.0.1 the clone() method was deprecated in favour of clone keyword
        return @$object->clone();
    }
    return @clone($object);
}

It throws ERROR: Imagick::clone is DEPRECATED....

After a research, it appears the php method phpversion('imagick') is returning @PACKAGE_VERSION@ instead of the actual version number, therefore version_compare() always returns -1, meaning it will always use the deprecated Imagick::clone line of code no matter what.

I have tried using Imagick::getVersion() just for sports and it still returns the same weird @PACKAGE_VERSION@ string.

Can I downgrade to 3.13 somehow? If not, is there any fix I can apply to make the phpversion('imagick') return an actual version without forking the TCPDF repo and changing the code myself to not check for older version?

Thank you very much.
