<div>Well spotted, thanks! I assume you're using Cyrus 2.5.x?<br></div>
<div> </div>
<div>configure is generated by autoconf from configure.ac, so the correct place to fix this is in configure.ac, at least on-going.<br></div>
<div> </div>
<div>It looks like the problem is due to the PKG_CHECK_MODULES macro first being invoked inside a bash conditional. The problem, and its fix, is discussed in section 3.4 here: <a href="https://autotools.io/pkgconfig/pkg_check_modules.html">https://autotools.io/pkgconfig/pkg_check_modules.html</a><br></div>
<div> </div>
<div>And, it looks like it's already fixed on master, so I'll backport the fix to the 2.5 branch, and it will be included in the next release.<br></div>

Does the event notification component make any sense under normal use conditions (IMAP with email clients like Thunderbird and Outlook)? If I understand it correctly, it's only needed for some special types of notifications like for xmpp clients, debugging and similar, not for something implemented in normal IMAP clients, so it makes sense to disable it for production use. Am I right?</span></span><br></div>

<div>I don't know much about it myself -- can someone else field this question please?<br></div>
<div> </div>
<div>Cheers,<br></div>
